• Problem designing xsd schema - because of a variable element name

  - by ssaboum

  Hi everyone, i'm not the best at creating XSD schema as this is actually my first one, i would like to validate an xml that must look like this : <?xml version="1.0"?> <Data> <FIELD name='toto'> <META mono='false' dynamic='false'> <COLUMN1> <REFTABLE>table</REFTABLE> <REFCOLUMN>key_column</REFCOLUMN> <REFLABELCOLUMN>test_column</REFLABELCOLUMN> </COLUMN1> <COLUMN2> <REFTABLE>table</REFTABLE> <REFCOLUMN>key_column</REFCOLUMN> <REFLABELCOLUMN>test_column</REFLABELCOLUMN> </COLUMN2> </META> <VALUEs> <VALUE>...</VALUE> </VALUEs> </FIELD> My problem is that into the META block the tags "COLUMN1","COLUMN2" are always different, it may become COLUMNxxx. For now my schema is : <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:element name="Data"> <xsd:complexType> <xsd:sequence> <xsd:element name="FIELD" type="Field" /> </xsd:sequence> <xsd:attribute name="id" type="xsd:int" use="required" /> </xsd:complexType> </xsd:element> <xsd:complexType name="dataSourceDef"> <xsd:sequence> <xsd:element name="DSD_REFTABLE" type="xsd:string" /> <xsd:element name="DSD_REFCOLUMN" type="xsd:string" /> <xsd:element name="DSD_REFLABELCOLUMN" type="xsd:string" /> </xsd:sequence> </xsd:complexType> <xsd:complexType name="MetaTag"> <xsd:sequence> <xsd:any processContents="lax" /> </xsd:sequence> <xsd:attribute name="mono" type="xsd:string" use="required" /> <xsd:attribute name="dynamic" type="xsd:string" use="required"/> </xsd:complexType> <xsd:complexType name="Field"> <xsd:sequence> <xsd:element name="META" type="MetaTag" minOccurs="1" /> <xsd:element name="VALUEs"> <xsd:complexType> <xsd:sequence> <xsd:any processContents="lax" /> </xsd:sequence> </xsd:complexType> </xsd:element> </xsd:sequence> <xsd:attribute name="name" type="xsd:string" use="required"/> </xsd:complexType> </xsd:schema> And i just can't get it to work, i don't know how to handle the fact that a precise level of my nodes isn't clear, and the rest is. Would you help me please ? thx

• Jquery validation does not stop execution of "code behind" code of asp.net button

  - by shahk26

  Hi, I have a asp.net button which has click event which basically adds data into datbase. I also have a radiobuttonlist(i.e Approve / Decline) and a textbox. If user selects decline, the textbox becomes visible. I want to run validation that when user clicks on submit button, if the decline is selected then the textbox can not blank. I have used jquery validation for that. when I click button, the message apppears next to textbox that the field is required but it does not stop the execution of code behind. i.e.It adds data into database. Here is my code. <script type="text/javascript" language="javascript"> $(function() { $('#declinediv').hide(); //////// var $radBtn = $("table.rblist input:radio"); $radBtn.click(function() { var $radChecked = $(':radio:checked'); var value = $radChecked.val(); if (value == 'Decline' || value == 'Approve') { if (value == 'Decline') $('#declinediv').show(); else $('#declinediv').hide(); } else { $('#declinediv').hide(); } }); ////////////////////////// $("#aspnetForm").validate({ rules: { <%=txtdeclinereason.UniqueID %>: { minlength: 2, required: true } }, messages: { <%=txtdeclinereason.UniqueID %>:{ required: "* Required Field *", minlength: "* Please enter atleast 2 characters *" } }, onsubmit: true }); ////////////////////////////////// $('#btnsubmit').click(function(evt){ var isValid = $("#aspnetForm").valid(); if (!isValid) { evt.preventDefault(); } }); }); function myredirect(v, m, f) { window.location.href = v; } </script> <table style="border: 1px black solid; text-align: center; vertical-align: middle" width="100%"> <tr> <td> <asp:RadioButtonList ID="rbtnlstapprover" runat="server" RepeatDirection="Horizontal" CssClass="rblist" DataTextField="username" DataValueField="emailaddress"> <asp:ListItem Text="Approve" Value="Approve" /> <asp:ListItem Text="Decline" Value="Decline" /> </asp:RadioButtonList> <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="rbtnlstapprover" Text="*" ErrorMessage="Please select atleast one Approver" ValidationGroup="approvalgroup" Display="Dynamic" /> </td> </tr> <tr> <td> <div id="declinediv"> <asp:TextBox ID="txtdeclinereason" runat="server" TextMode="MultiLine" Columns="80" Rows="5" /> </div> </td> </tr> <tr> <td> <asp:Button ID="btnsubmit" runat="server" Text="Submit" CssClass="RegularButton" CausesValidation="true" ValidationGroup="approvalgroup" OnClick="btnsubmit_Click" /> </td> </tr> </table> How do I stop the execution of code behind? Thanks for your help.

• Drupal 7 Forms API Conditional Logic not working in IE

  - by Francis Yaconiello

  I have a drupal 7 form with a bunch of fields: $form['account_type'] = array( '#title' => t('Utility Account Type'), '#type' => 'select', '#options' => necp_enrollment_administration_portal_account_type_options(), '#required' => TRUE, '#default_value' => isset($form_state['values']['account_type']) ? $form_state['values']['account_type'] : '', ); // Should show if account_type = 1 $form['home_wrapper'] = array( '#type' => 'fieldset', '#states' => array( 'visible' => array( ':input[name="account_type"]' => array('value' => 1), ), ), ); $form['home_wrapper']['first_name_1'] = array( '#title' => t('Primary Account First Name'), '#type' => 'textfield', '#default_value' => isset($form_state['values']['first_name_1']) ? $form_state['values']['first_name_1'] : '', '#states' => array( 'required' => array( ':input[name="account_type"]' => array('value' => 1), ), ), ); $form['home_wrapper']['last_name_1'] = array( '#title' => t('Primary Account Last Name'), '#type' => 'textfield', '#default_value' => isset($form_state['values']['last_name_1']) ? $form_state['values']['last_name_1'] : '', '#states' => array( 'required' => array( ':input[name="account_type"]' => array('value' => 1), ), ), ); // Should show if account_type = 2 $form['business_wrapper'] = array( '#type' => 'fieldset', '#states' => array( 'visible' => array( ':input[name="account_type"]' => array('value' => 2), ), ), ); $form['business_wrapper']['company_name'] = array( '#title' => t('Company/Organization'), '#type' => 'textfield', '#default_value' => isset($form_state['values']['company_name']) ? $form_state['values']['company_name'] : '', '#states' => array( 'required' => array( ':input[name="account_type"]' => array('value' => 2), ), ), ); In Firefox/Chrome/Opera all versions this form behaves as it should. However in all versions of IE the form initializes with display:none; style on all of the conditional fields regardless of what the value in account_type is. Changing the selected option of account_type does not effect the hidden status. Any tips on debugging this form would be awesome. Notes: I am not much of a Drupal developer, I inherited this site. Just trying to iron out the last couple bugs so we can go live there are more fields than are listed above, I just gave you some of the applicable ones so that you could get the gist of how my forms were setup current url for the form in development: https://northeastcleanpower.com/enroll_new I'm using http://www.browserstack.com/ to debug IE 7 - 10pp4 (I think we only have to support 8 and up though) I've also tried: ':select[name="account_type"]' => array('value' => 1), '#edit-account-type' => array('value' => 1),

  - by MKS

  Hi Guys, I am using XSLT and XML. I have got below XML. <documentCountryInformation> <countryCode>US</countryCode> <countryName>United States</countryName> <sufficientDocumentation>Conditional</sufficientDocumentation> <sectionInformation> <sectionName>Health</sectionName> <documentParagraph paragraphId="23628"> <paragraphType>Requirement</paragraphType> <paragraphText> <p> Vaccination for <strong>yellow fever</strong> Persons without valid yellow fever certification, if required, are subject to quarantine for a period up to 6 days. </p> </paragraphText> </documentParagraph> </sectionInformation> </documentCountryInformation> <documentCountryInformation> <countryCode>IN</countryCode> <countryName>India</countryName> <sufficientDocumentation>Conditional</sufficientDocumentation> <sectionInformation> <sectionName>Health</sectionName> <documentParagraph paragraphId="23648"> <paragraphType>Requirement</paragraphType> <paragraphText> <p> Vaccination for <strong>Dengue fever</strong> Persons without valid yellow fever certification, if required, are subject to quarantine for a period up to 3 days. </p> </paragraphText> </documentParagraph> </sectionInformation> </documentCountryInformation> Above is the part of full xml and you can see there are two records of same type, now I have got the <countryName> in parameters of XSLT in above example my countryName parameter will contain this type of data "United States,India", Now I want to split the parameter data and further it will check the XML having same country name and display the data according, I mean there will be loop on country name and below is desired HTML. <div class="resultsContainer" id="divTransit"> <h3>Transit - United States (US)</h3> <p> Vaccination for <strong>yellow fever</strong> Persons without valid yellow fever certification, if required, are subject to quarantine for a period up to 6 days. </p> <h3>Transit - India (IN)</h3> <p> Vaccination for <strong>Dengue fever</strong> Persons without valid yellow fever certification, if required, are subject to quarantine for a period up to 3 days. </p> </div>

• asp.net mvc xval validation

  - by mctayl

  Hi there I am using xval for the first time, it seems to work fine for required fields, However I am having some issues first of all it does not seem to validate booleans and also client validation is not working for me, this is not a major issue for me, the one that I really need to work is the stringlength property. It seems to do something because the form is not posted when the string length is exceeded, however no error message is displayed to the user which is obviously not what I want, has anyone been able to do this successfully? My model goes like this using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel.DataAnnotations; namespace PitchPortal.Core { public class DocumentMetadata { //[Required] // public bool visibility { get; set; } [Required,StringLength(10, ErrorMessage = "title is too long")] public string title { get; set; } [Required, StringLength(10, ErrorMessage = "description is too long")] public string description { get; set; } [Required, StringLength(10, ErrorMessage = "summary is too long")] public string summary { get; set; } } } the html goes like this <div id="results" title="Upload results"/> <form id="myForm" action="<%=Url.Action("New") %>" method="post" enctype="multipart/form-data"> <% Html.EnableClientValidation(); %> <%= Html.ValidationSummary() %> <table> <tr> <td> <%=Html.Label("File")%></td> <td> <input type="file" id="file1" name="fileUpload" /> <br /> <%=Html.SubmitButton<DocumentController>(x => x.Upload(), "GetImage", "")%> </td> <td> <%=Html.ValidationMessage("file1")%> </td> </tr> <tr> <td> <%=Html.Label("Visible")%></td> <td> <%= Html.RadioButton( "visibility",true,true) %>true <%= Html.RadioButton("visibility", false)%>false </td> <td> <%= Html.ValidationMessage("visibility")%> </td> </tr> <tr> <td> <%=Html.Label("Title")%></td> <td> <%=Html.TextBox("doc.title")%></td> <td> <%= Html.ValidationMessage("doc.title")%></td> </tr> <tr> <td> <%=Html.Label("Description")%></td> <td><%= Html.TextArea("doc.description")%></td> <td><%= Html.ValidationMessage("doc.description")%></td> </tr> <tr> <td> <%=Html.Label("Summary")%></td> <td> <%= Html.TextArea("doc.summary")%></td> <td> <%= Html.ValidationMessage("doc.summary")%></td> </tr> <tr> <td> <%=Html.Label("Filetype")%></td> <td> <%= Html.DropDownList("Filetype_id", (IEnumerable<SelectListItem>)ViewData.Model.AllFiletypesList)%> </td> <td> <%= Html.ValidationMessage("doc.Filetype_id")%> </td> </tr> <tr> <td> <%=Html.Label("Category")%></td> <td><%= Html.DropDownList("cat.parent_id", (IEnumerable<SelectListItem>)ViewData.Model.AllCategoriesList, "-please select item-", new { className = "unselected" })%> </td> <td><%= Html.ValidationMessage("cat.parent_id")%> </td> </tr> <% if (Session["TempFolder"] == null) { for (int i = 1; i < 6; i++) { %> <tr> <td> <%=Html.Label("Shot "+i.ToString()) %> </td> <td><input type="file" id="image_<%= i.ToString() %>" name="image_<%= i.ToString() %>" /></td> </tr> <% } }%> <tr> <td><input type="submit" value="save"/></td> </tr> </table> </form> </div>

• php validation code format

  - by user2970887

  Okay I have this MySQL database form and am trying to add validation to it. After 2 days of fighting with it, I thought I would get some advice. Would like that the selected item from dropdown and Firstname, Phone, Email, are all required. Then I want to verify that the data in the Firstname, Lastname, Phone (doesn't have to be any special format), Email and Comments are all acceptable formats before putting in database. Here is what I have so far: <?php include('inc_header.php'); if(isset($_POST['add'])) { require('dbcon.php'); if(! get_magic_quotes_gpc() ) { $Id = addslashes ($_POST['Id']); $List = addslashes ($_POST['List']); $Firstname = addslashes ($_POST['Firstname']); $Lastname = addslashes ($_POST['Lastname']); $Phone = addslashes ($_POST['Phone']); $Email= addslashes ($_POST['Email']); $Calltime = addslashes ($_POST['Calltime']); $Comment = addslashes ($_POST['Comment']); } else { $Id = $_POST['Id']; $Date = $_POST['Date']; $List = $_POST['List']; $Firstname = $_POST['Firstname']; $Lastname = $_POST['Lastname']; $Phone = $_POST['Phone']; $Email = $_POST['Email']; $Calltime = $_POST['Calltime']; $Comment = $_POST['Comment']; } $error = ''; //put chosen function here function validate_Firstname($input, $pattern = "/([A-Za-z0-9])") { return !preg_match($pattern, $input); } function validate_Phone($input, $pattern = "/([A-Za-z0-9])") { return !preg_match($pattern, $input); } function isValidEmail( $Email ){ return filter_var( $Email, FILTER_VALIDATE_EMAIL ); } //get values and validate each one as required $List = mysql_real_escape_string($_POST['List']); if(!$List){ $error .= "Please choose one<br />"; } $Firstname = mysql_real_escape_string($_POST['Firstname']); if(!$Firstname){ $error .= "First name is required<br />"; } //get values and validate each one as required $Lastname = mysql_real_escape_string($_POST['Lastname']); if(!$Lastname){ $error .= "Last name is required<br />"; } //repeat for each field $Email = mysql_real_escape_string($_POST['Email']); if(!isValidEmail($Email)){ $error .= "The email entered is invalid<br />"; } //and so on... if(!$error){ //add insert into database code here $sql = "INSERT INTO contacts ".

• rake migration aborted: could not find table 'roles'

  - by user464180

  I just inherited code that I'm attempting to run the migrations for but I keep getting a rake aborted error. I've come across others that have what appears to be similar issues, but most involved Heroku and I'm trying to run this locally (to start.) I've tried troubleshooting using both PostgreSQL and SQLite, and both produce the same issue. The table "roles" referenced is the second migration called, so I'm having a hard time figuring out what is causing it to not get built. Any and all assistance is greatly appreciated. Thanks in advance. Here's the roles migration: class CreateRoles < ActiveRecord::Migration def change create_table :roles do |t| t.string :name t.timestamps end end end Here is the trace for SQLite: ** Invoke db:migrate (first_time) ** Invoke environment (first_time) ** Execute environment rake aborted!

• 11415 compile errors FTW?!

  - by Koning Baard

  Hello. This is something I've really never seen but, I downloaded the source code of the sine wave example at http://www.audiosynth.com/sinewavedemo.html . It is in an old Project Builder Project format, and I want to compile it with Xcode (GCC). However, Xcode gives me 11415 compile errors.

• Framework 4 Features: Summary of Security enhancements

  - by Anthony Shorten

  In the last log entry I mentioned one of the new security features in Oracle Utilities Application Framework 4.0.1. Security is one of the major "tent poles" (to borrow a phrase from Steve Jobs) in this release of the framework. There are a number of security related enhancements requested by customers and as a result of internal reviews that we have introduced. Here is a summary of some of the security enchancements we have added in this release: Security Cache Changes - Security authorization information is automatically cached on the server for performance reasons (security is checked for every single call the product makes for all modes of access). Prior to this release the cache auto-refreshed every 30 minutes (or so). This has beem made more nimble by supporting a cache refresh every minute (or so). This means authorization changes are reflected quicker than before. Business Level security - Business Services are configurable services that are based upon Application Services. Typically, the business service inherited its security profile from its parent service. Whilst this is sufficient for most needs, it is now required to further specify security on the Business Service definition itself. This will allow granular security and allow the same application service to be exposed as different Business Services with their own security. This is particularly useful when you base a Business Service on a query zone. User Propogation - As with other client server applications, the database connections are pooled and shared as needed. This means that a common database user is used to access the database from the pool to allow sharing. Unfortunently, this means that tracability at the database level is that much harder. In Oracle Utilities Application Framework V4 the end userid is now propogated to the database using the CLIENT_IDENTIFIER as part of the Oracle JDBC connection API. This not only means that the common database userid is still used but the end user is indentifiable for the duration of the database call. This can be used for monitoring or to hook into Oracle's database security products. This enhancement is only available to Oracle Database customers. Enhanced Security Definitions - Security Administrators use the product browser front end to control access rights of defined users. While this is sufficient for most sites, a new security portal has been introduced to speed up the maintenance of security information. Oracle Identity Manager Integration - With the popularity of Oracle's Identity Management Suite, the Framework now provides an integration adapter and Identity Manager Generic Transport Connector (GTC) to allow users and group membership to be provisioned to any Oracle Utilities Application Framework based product from Oracle's Identity Manager. This is also available for Oracle Utilties Application Framework V2.2 customers. Refer to My Oracle Support KBid 970785.1 - Oracle Identity Manager Integration Overview. Audit On Inquiry - Typically the configurable audit facility in the Oracle Utilities Application Framework is used to audit changes to records. In Oracle Utilities Application Framework the Business Services and Service Scripts could be configured to audit inquiries as well. Now it is possible to attach auditing capabilities to zones on the product (including base package ones). Time Zone Support - In some of the Oracle Utilities Application Framework based products, the timezone of the end user is a factor in the processing. The user object has been extended to allow the recording of time zone information for use in product functionality. JAAS Suport - Internally the Oracle Utilities Application Framework uses a number of techniques to validate and transmit security information across the architecture. These various methods have been reconciled into using Java Authentication and Authorization Services for standardized security. This is strictly an internal change with no direct on how security operates externally. JMX Based Cache Management - In the last bullet point, I mentioned extra security applied to cache management from the browser. Alternatively a JMX based interface is now provided to allow IT operations to control the cache without the browser interface. This JMX capability can be initiated from a JSR120 compliant JMX console or JMX browser. I will be writing another more detailed blog entry on the JMX enhancements as it is quite a change and an exciting direction for the product line. Data Patch Permissions - The database installer provided with the product required lower levels of security for some operations. At some sites they wanted the ability for non-DBA's to execute the utilities in a controlled fashion. The framework now allows feature configuration to allow delegation for patch execution. User Enable Support - At some sites, the use of temporary staff such as contractors is commonplace. In this scenario, temporary security setups were required and used. A potential issue has arisen when the contractor left the company. Typically the IT group would remove the contractor from the security repository to prevent login using that contractors userid but the userid could NOT be removed from the authorization model becuase of audit requirements (if any user in the product updates financials or key data their userid is recorded for audit purposes). It is now possible to effectively diable the user from the security model to prevent any use of the useridwhilst retaining audit information. These are a subset of the security changes in Oracle Utilities Application Framework. More details about the security capabilities of the product is contained in My Oracle Support KB Id 773473.1 - Oracle Utilities Application Framework Security Overview.

• What&rsquo;s New in ASP.NET 4.0 Part Two: WebForms and Visual Studio Enhancements

  - by Rick Strahl

  In the last installment I talked about the core changes in the ASP.NET runtime that I’ve been taking advantage of. In this column, I’ll cover the changes to the Web Forms engine and some of the cool improvements in Visual Studio that make Web and general development easier. WebForms The WebForms engine is the area that has received most significant changes in ASP.NET 4.0. Probably the most widely anticipated features are related to managing page client ids and of ViewState on WebForm pages. Take Control of Your ClientIDs Unique ClientID generation in ASP.NET has been one of the most complained about “features” in ASP.NET. Although there’s a very good technical reason for these unique generated ids - they guarantee unique ids for each and every server control on a page - these unique and generated ids often get in the way of client-side JavaScript development and CSS styling as it’s often inconvenient and fragile to work with the long, generated ClientIDs. In ASP.NET 4.0 you can now specify an explicit client id mode on each control or each naming container parent control to control how client ids are generated. By default, ASP.NET generates mangled client ids for any control contained in a naming container (like a Master Page, or a User Control for example). The key to ClientID management in ASP.NET 4.0 are the new ClientIDMode and ClientIDRowSuffix properties. ClientIDMode supports four different ClientID generation settings shown below. For the following examples, imagine that you have a Textbox control named txtName inside of a master page control container on a WebForms page. <%@Page Language="C#"      MasterPageFile="~/Site.Master"     CodeBehind="WebForm2.aspx.cs"     Inherits="WebApplication1.WebForm2"  %> <asp:Content ID="content"  ContentPlaceHolderID="content"               runat="server"               ClientIDMode="Static" >       <asp:TextBox runat="server" ID="txtName" /> </asp:Content> The four available ClientIDMode values are: AutoID This is the existing behavior in ASP.NET 1.x-3.x where full naming container munging takes place. <input name="ctl00$content$txtName" type="text"        id="ctl00_content_txtName" /> This should be familiar to any ASP.NET developer and results in fairly unpredictable client ids that can easily change if the containership hierarchy changes. For example, removing the master page changes the name in this case, so if you were to move a block of script code that works against the control to a non-Master page, the script code immediately breaks. Static This option is the most deterministic setting that forces the control’s ClientID to use its ID value directly. No naming container naming at all is applied and you end up with clean client ids: <input name="ctl00$content$txtName"         type="text" id="txtName" /> Note that the name property which is used for postback variables to the server still is munged, but the ClientID property is displayed simply as the ID value that you have assigned to the control. This option is what most of us want to use, but you have to be clear on that because it can potentially cause conflicts with other controls on the page. If there are several instances of the same naming container (several instances of the same user control for example) there can easily be a client id naming conflict. Note that if you assign Static to a data-bound control, like a list child control in templates, you do not get unique ids either, so for list controls where you rely on unique id for child controls, you’ll probably want to use Predictable rather than Static. I’ll write more on this a little later when I discuss ClientIDRowSuffix. Predictable The previous two values are pretty self-explanatory. Predictable however, requires some explanation. To me at least it’s not in the least bit predictable. MSDN defines this value as follows: This algorithm is used for controls that are in data-bound controls. The ClientID value is generated by concatenating the ClientID value of the parent naming container with the ID value of the control. If the control is a data-bound control that generates multiple rows, the value of the data field specified in the ClientIDRowSuffix property is added at the end. For the GridView control, multiple data fields can be specified. If the ClientIDRowSuffix property is blank, a sequential number is added at the end instead of a data-field value. Each segment is separated by an underscore character (_). The key that makes this value a bit confusing is that it relies on the parent NamingContainer’s ClientID to build its own ClientID value. This effectively means that the value is not predictable at all but rather very tightly coupled to the parent naming container’s ClientIDMode setting. For my simple textbox example, if the ClientIDMode property of the parent naming container (Page in this case) is set to “Predictable” you’ll get this: <input name="ctl00$content$txtName" type="text"         id="content_txtName" /> which gives an id that based on walking up to the currently active naming container (the MasterPage content container) and starting the id formatting from there downward. Think of this as a semi unique name that’s guaranteed unique only for the naming container. If, on the other hand, the Page is set to “AutoID” you get the following with Predictable on txtName: <input name="ctl00$content$txtName" type="text"         id="ctl00_content_txtName" /> The latter is effectively the same as if you specified AutoID because it inherits the AutoID naming from the Page and Content Master Page control of the page. But again - predictable behavior always depends on the parent naming container and how it generates its id, so the id may not always be exactly the same as the AutoID generated value because somewhere in the NamingContainer chain the ClientIDMode setting may be set to a different value. For example, if you had another naming container in the middle that was set to Static you’d end up effectively with an id that starts with the NamingContainers id rather than the whole ctl000_content munging. The most common use for Predictable is likely to be for data-bound controls, which results in each data bound item getting a unique ClientID. Unfortunately, even here the behavior can be very unpredictable depending on which data-bound control you use - I found significant differences in how template controls in a GridView behave from those that are used in a ListView control. For example, GridView creates clean child ClientIDs, while ListView still has a naming container in the ClientID, presumably because of the template container on which you can’t set ClientIDMode. Predictable is useful, but only if all naming containers down the chain use this setting. Otherwise you’re right back to the munged ids that are pretty unpredictable. Another property, ClientIDRowSuffix, can be used in combination with ClientIDMode of Predictable to force a suffix onto list client controls. For example: <asp:GridView runat="server" ID="gvItems"              AutoGenerateColumns="false"             ClientIDMode="Static"              ClientIDRowSuffix="Id">     <Columns>     <asp:TemplateField>         <ItemTemplate>             <asp:Label runat="server" id="txtName"                        Text='<%# Eval("Name") %>'                   ClientIDMode="Predictable"/>         </ItemTemplate>     </asp:TemplateField>     <asp:TemplateField>         <ItemTemplate>         <asp:Label runat="server" id="txtId"                     Text='<%# Eval("Id") %>'                     ClientIDMode="Predictable" />         </ItemTemplate>     </asp:TemplateField>     </Columns>  </asp:GridView> generates client Ids inside of a column in the master page described earlier: <td>     <span id="txtName_0">Rick</span> </td> where the value after the underscore is the ClientIDRowSuffix field - in this case “Id” of the item data bound to the control. Note that all of the child controls require ClientIDMode=”Predictable” in order for the ClientIDRowSuffix to be applied, and the parent GridView controls need to be set to Static either explicitly or via Naming Container inheritance to give these simple names. It’s a bummer that ClientIDRowSuffix doesn’t work with Static to produce this automatically. Another real problem is that other controls process the ClientIDMode differently. For example, a ListView control processes the Predictable ClientIDMode differently and produces the following with the Static ListView and Predictable child controls: <span id="ctrl0_txtName_0">Rick</span> I couldn’t even figure out a way using ClientIDMode to get a simple ID that also uses a suffix short of falling back to manually generated ids using <%= %> expressions instead. Given the inconsistencies inside of list controls using <%= %>, ids for the ListView might not be a bad idea anyway. Inherit The final setting is Inherit, which is the default for all controls except Page. This means that controls by default inherit the parent naming container’s ClientIDMode setting. For more detailed information on ClientID behavior and different scenarios you can check out a blog post of mine on this subject: http://www.west-wind.com/weblog/posts/54760.aspx. ClientID Enhancements Summary The ClientIDMode property is a welcome addition to ASP.NET 4.0. To me this is probably the most useful WebForms feature as it allows me to generate clean IDs simply by setting ClientIDMode="Static" on either the page or inside of Web.config (in the Pages section) which applies the setting down to the entire page which is my 95% scenario. For the few cases when it matters - for list controls and inside of multi-use user controls or custom server controls) - I can use Predictable or even AutoID to force controls to unique names. For application-level page development, this is easy to accomplish and provides maximum usability for working with client script code against page controls. ViewStateMode Another area of large criticism for WebForms is ViewState. ViewState is used internally by ASP.NET to persist page-level changes to non-postback properties on controls as pages post back to the server. It’s a useful mechanism that works great for the overall mechanics of WebForms, but it can also cause all sorts of overhead for page operation as ViewState can very quickly get out of control and consume huge amounts of bandwidth in your page content. ViewState can also wreak havoc with client-side scripting applications that modify control properties that are tracked by ViewState, which can produce very unpredictable results on a Postback after client-side updates. Over the years in my own development, I’ve often turned off ViewState on pages to reduce overhead. Yes, you lose some functionality, but you can easily implement most of the common functionality in non-ViewState workarounds. Relying less on heavy ViewState controls and sticking with simpler controls or raw HTML constructs avoids getting around ViewState problems. In ASP.NET 3.x and prior, it wasn’t easy to control ViewState - you could turn it on or off and if you turned it off at the page or web.config level, you couldn’t turn it back on for specific controls. In short, it was an all or nothing approach. With ASP.NET 4.0, the new ViewStateMode property gives you more control. It allows you to disable ViewState globally either on the page or web.config level and then turn it back on for specific controls that might need it. ViewStateMode only works when EnableViewState="true" on the page or web.config level (which is the default). You can then use ViewStateMode of Disabled, Enabled or Inherit to control the ViewState settings on the page. If you’re shooting for minimal ViewState usage, the ideal situation is to set ViewStateMode to disabled on the Page or web.config level and only turn it back on particular controls: <%@Page Language="C#"      CodeBehind="WebForm2.aspx.cs"     Inherits="Westwind.WebStore.WebForm2"        ClientIDMode="Static"                ViewStateMode="Disabled"     EnableViewState="true"  %> <!-- this control has viewstate  --> <asp:TextBox runat="server" ID="txtName"  ViewStateMode="Enabled" />       <!-- this control has no viewstate - it inherits  from parent container --> <asp:TextBox runat="server" ID="txtAddress" /> Note that the EnableViewState="true" at the Page level isn’t required since it’s the default, but it’s important that the value is true. ViewStateMode has no effect if EnableViewState="false" at the page level. The main benefit of ViewStateMode is that it allows you to more easily turn off ViewState for most of the page and enable only a few key controls that might need it. For me personally, this is a perfect combination as most of my WebForm apps can get away without any ViewState at all. But some controls - especially third party controls - often don’t work well without ViewState enabled, and now it’s much easier to selectively enable controls rather than the old way, which required you to pretty much turn off ViewState for all controls that you didn’t want ViewState on. Inline HTML Encoding HTML encoding is an important feature to prevent cross-site scripting attacks in data entered by users on your site. In order to make it easier to create HTML encoded content, ASP.NET 4.0 introduces a new Expression syntax using <%: %> to encode string values. The encoding expression syntax looks like this: <%: "<script type='text/javascript'>" +     "alert('Really?');</script>" %> which produces properly encoded HTML: &lt;script type=&#39;text/javascript&#39; &gt;alert(&#39;Really?&#39;);&lt;/script&gt; Effectively this is a shortcut to: <%= HttpUtility.HtmlEncode( "<script type='text/javascript'>" + "alert('Really?');</script>") %> Of course the <%: %> syntax can also evaluate expressions just like <%= %> so the more common scenario applies this expression syntax against data your application is displaying. Here’s an example displaying some data model values: <%: Model.Address.Street %> This snippet shows displaying data from your application’s data store or more importantly, from data entered by users. Anything that makes it easier and less verbose to HtmlEncode text is a welcome addition to avoid potential cross-site scripting attacks. Although I listed Inline HTML Encoding here under WebForms, anything that uses the WebForms rendering engine including ASP.NET MVC, benefits from this feature. ScriptManager Enhancements The ASP.NET ScriptManager control in the past has introduced some nice ways to take programmatic and markup control over script loading, but there were a number of shortcomings in this control. The ASP.NET 4.0 ScriptManager has a number of improvements that make it easier to control script loading and addresses a few of the shortcomings that have often kept me from using the control in favor of manual script loading. The first is the AjaxFrameworkMode property which finally lets you suppress loading the ASP.NET AJAX runtime. Disabled doesn’t load any ASP.NET AJAX libraries, but there’s also an Explicit mode that lets you pick and choose the library pieces individually and reduce the footprint of ASP.NET AJAX script included if you are using the library. There’s also a new EnableCdn property that forces any script that has a new WebResource attribute CdnPath property set to a CDN supplied URL. If the script has this Attribute property set to a non-null/empty value and EnableCdn is enabled on the ScriptManager, that script will be served from the specified CdnPath. [assembly: WebResource(    "Westwind.Web.Resources.ww.jquery.js",    "application/x-javascript",    CdnPath =  "http://mysite.com/scripts/ww.jquery.min.js")] Cool, but a little too static for my taste since this value can’t be changed at runtime to point at a debug script as needed, for example. Assembly names for loading scripts from resources can now be simple names rather than fully qualified assembly names, which make it less verbose to reference scripts from assemblies loaded from your bin folder or the assembly reference area in web.config: <asp:ScriptManager runat="server" id="Id"          EnableCdn="true"         AjaxFrameworkMode="disabled">     <Scripts>         <asp:ScriptReference          Name="Westwind.Web.Resources.ww.jquery.js"         Assembly="Westwind.Web" />     </Scripts>        </asp:ScriptManager> The ScriptManager in 4.0 also supports script combining via the CompositeScript tag, which allows you to very easily combine scripts into a single script resource served via ASP.NET. Even nicer: You can specify the URL that the combined script is served with. Check out the following script manager markup that combines several static file scripts and a script resource into a single ASP.NET served resource from a static URL (allscripts.js): <asp:ScriptManager runat="server" id="Id"          EnableCdn="true"         AjaxFrameworkMode="disabled">     <CompositeScript          Path="~/scripts/allscripts.js">         <Scripts>             <asp:ScriptReference                    Path="~/scripts/jquery.js" />             <asp:ScriptReference                    Path="~/scripts/ww.jquery.js" />             <asp:ScriptReference            Name="Westwind.Web.Resources.editors.js"                 Assembly="Westwind.Web" />         </Scripts>     </CompositeScript> </asp:ScriptManager> When you render this into HTML, you’ll see a single script reference in the page: <script src="scripts/allscripts.debug.js"          type="text/javascript"></script> All you need to do to make this work is ensure that allscripts.js and allscripts.debug.js exist in the scripts folder of your application - they can be empty but the file has to be there. This is pretty cool, but you want to be real careful that you use unique URLs for each combination of scripts you combine or else browser and server caching will easily screw you up royally. The script manager also allows you to override native ASP.NET AJAX scripts now as any script references defined in the Scripts section of the ScriptManager trump internal references. So if you want custom behavior or you want to fix a possible bug in the core libraries that normally are loaded from resources, you can now do this simply by referencing the script resource name in the Name property and pointing at System.Web for the assembly. Not a common scenario, but when you need it, it can come in real handy. Still, there are a number of shortcomings in this control. For one, the ScriptManager and ClientScript APIs still have no common entry point so control developers are still faced with having to check and support both APIs to load scripts so that controls can work on pages that do or don’t have a ScriptManager on the page. The CdnUrl is static and compiled in, which is very restrictive. And finally, there’s still no control over where scripts get loaded on the page - ScriptManager still injects scripts into the middle of the HTML markup rather than in the header or optionally the footer. This, in turn, means there is little control over script loading order, which can be problematic for control developers. MetaDescription, MetaKeywords Page Properties There are also a number of additional Page properties that correspond to some of the other features discussed in this column: ClientIDMode, ClientTarget and ViewStateMode. Another minor but useful feature is that you can now directly access the MetaDescription and MetaKeywords properties on the Page object to set the corresponding meta tags programmatically. Updating these values programmatically previously required either <%= %> expressions in the page markup or dynamic insertion of literal controls into the page. You can now just set these properties programmatically on the Page object in any Control derived class on the page or the Page itself: Page.MetaKeywords = "ASP.NET,4.0,New Features"; Page.MetaDescription = "This article discusses the new features in ASP.NET 4.0"; Note, that there’s no corresponding ASP.NET tag for the HTML Meta element, so the only way to specify these values in markup and access them is via the @Page tag: <%@Page Language="C#"      CodeBehind="WebForm2.aspx.cs"     Inherits="Westwind.WebStore.WebForm2"      ClientIDMode="Static"                MetaDescription="Article that discusses what's                      new in ASP.NET 4.0"     MetaKeywords="ASP.NET,4.0,New Features" %> Nothing earth shattering but quite convenient. Visual Studio 2010 Enhancements for Web Development For Web development there are also a host of editor enhancements in Visual Studio 2010. Some of these are not Web specific but they are useful for Web developers in general. Text Editors Throughout Visual Studio 2010, the text editors have all been updated to a new core engine based on WPF which provides some interesting new features for various code editors including the nice ability to zoom in and out with Ctrl-MouseWheel to quickly change the size of text. There are many more API options to control the editor and although Visual Studio 2010 doesn’t yet use many of these features, we can look forward to enhancements in add-ins and future editor updates from the various language teams that take advantage of the visual richness that WPF provides to editing. On the negative side, I’ve noticed that occasionally the code editor and especially the HTML and JavaScript editors will lose the ability to use various navigation keys like arrows, back and delete keys, which requires closing and reopening the documents at times. This issue seems to be well documented so I suspect this will be addressed soon with a hotfix or within the first service pack. Overall though, the code editors work very well, especially given that they were re-written completely using WPF, which was one of my big worries when I first heard about the complete redesign of the editors. Multi-Targeting Visual Studio now targets all versions of the .NET framework from 2.0 forward. You can use Visual Studio 2010 to work on your ASP.NET 2, 3.0 and 3.5 applications which is a nice way to get your feet wet with the new development environment without having to make changes to existing applications. It’s nice to have one tool to work in for all the different versions. Multi-Monitor Support One cool feature of Visual Studio 2010 is the ability to drag windows out of the Visual Studio environment and out onto the desktop including onto another monitor easily. Since Web development often involves working with a host of designers at the same time - visual designer, HTML markup window, code behind and JavaScript editor - it’s really nice to be able to have a little more screen real estate to work on each of these editors. Microsoft made a welcome change in the environment. IntelliSense Snippets for HTML and JavaScript Editors The HTML and JavaScript editors now finally support IntelliSense scripts to create macro-based template expansions that have been in the core C# and Visual Basic code editors since Visual Studio 2005. Snippets allow you to create short XML-based template definitions that can act as static macros or real templates that can have replaceable values that can be embedded into the expanded text. The XML syntax for these snippets is straight forward and it’s pretty easy to create custom snippets manually. You can easily create snippets using XML and store them in your custom snippets folder (C:\Users\rstrahl\Documents\Visual Studio 2010\Code Snippets\Visual Web Developer\My HTML Snippets and My JScript Snippets), but it helps to use one of the third-party tools that exist to simplify the process for you. I use SnippetEditor, by Bill McCarthy, which makes short work of creating snippets interactively (http://snippeteditor.codeplex.com/). Note: You may have to manually add the Visual Studio 2010 User specific Snippet folders to this tool to see existing ones you’ve created. Code snippets are some of the biggest time savers and HTML editing more than anything deals with lots of repetitive tasks that lend themselves to text expansion. Visual Studio 2010 includes a slew of built-in snippets (that you can also customize!) and you can create your own very easily. If you haven’t done so already, I encourage you to spend a little time examining your coding patterns and find the repetitive code that you write and convert it into snippets. I’ve been using CodeRush for this for years, but now you can do much of the basic expansion natively for HTML and JavaScript snippets. jQuery Integration Is Now Native jQuery is a popular JavaScript library and recently Microsoft has recently stated that it will become the primary client-side scripting technology to drive higher level script functionality in various ASP.NET Web projects that Microsoft provides. In Visual Studio 2010, the default full project template includes jQuery as part of a new project including the support files that provide IntelliSense (-vsdoc files). IntelliSense support for jQuery is now also baked into Visual Studio 2010, so unlike Visual Studio 2008 which required a separate download, no further installs are required for a rich IntelliSense experience with jQuery. Summary ASP.NET 4.0 brings many useful improvements to the platform, but thankfully most of the changes are incremental changes that don’t compromise backwards compatibility and they allow developers to ease into the new features one feature at a time. None of the changes in ASP.NET 4.0 or Visual Studio 2010 are monumental or game changers. The bigger features are language and .NET Framework changes that are also optional. This ASP.NET and tools release feels more like fine tuning and getting some long-standing kinks worked out of the platform. It shows that the ASP.NET team is dedicated to paying attention to community feedback and responding with changes to the platform and development environment based on this feedback. If you haven’t gotten your feet wet with ASP.NET 4.0 and Visual Studio 2010, there’s no reason not to give it a shot now - the ASP.NET 4.0 platform is solid and Visual Studio 2010 works very well for a brand new release. Check it out. © Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET

• Oracle Enterprise Data Quality: Ever Integration-ready

  - by Mala Narasimharajan

  It is closing in on a year now since Oracle’s acquisition of Datanomic, and the addition of Oracle Enterprise Data Quality (EDQ) to the Oracle software family. The big move has caused some big shifts in emphasis and some very encouraging excitement from the field.  To give an illustration, combined with a shameless promotion of how EDQ can help to give quick insights into your data, I did a quick Phrase Profile of the subject field of emails to the Global EDQ mailing list since it was set up last September. The results revealed a very clear theme:   Integration, Integration, Integration! As well as the important Siebel and Oracle Data Integrator (ODI) integrations, we have been asked about integration with a huge variety of Oracle applications, including EBS, Peoplesoft, CRM on Demand, Fusion, DRM, Endeca, RightNow, and more - and we have not stood still! While it would not have been possible to develop specific pre-integrations with all of the above within a year, we have developed a package of feature-rich out-of-the-box web services and batch processes that can be plugged into any application or middleware technology with ease. And with Siebel, they work out of the box. Oracle Enterprise Data Quality version 9.0.4 includes the Customer Data Services (CDS) pack – a ready set of standard processes with standard interfaces, to provide integrated: Address verification and cleansing  Individual matching Organization matching The services can are suitable for either Batch or Real-Time processing, and are enabled for international data, with simple configuration options driving the set of locale-specific dictionaries that are used. For example, large dictionaries are provided to support international name transcription and variant matching, including highly specialized handling for Arabic, Japanese, Chinese and Korean data. In total across all locales, CDS includes well over a million dictionary entries.   Excerpt from EDQ’s CDS Individual Name Standardization Dictionary CDS has been developed to replace the OEM of Informatica Identity Resolution (IIR) for attached Data Quality on the Oracle price list, but does this in a way that creates a ‘best of both worlds’ situation for customers, who can harness not only the out-of-the-box functionality of pre-packaged matching and standardization services, but also the flexibility of OEDQ if they want to customize the interfaces or the process logic, without having to learn more than one product. From a competitive point of view, we believe this stands us in good stead against our key competitors, including Informatica, who have separate ‘Identity Resolution’ and general DQ products, and IBM, who provide limited out-of-the-box capabilities (with a steep learning curve) in both their QualityStage data quality and Initiate matching products. Here is a brief guide to the main services provided in the pack: Address Verification and Standardization EDQ’s CDS Address Cleaning Process The Address Verification and Standardization service uses EDQ Address Verification (an OEM of Loqate software) to verify and clean addresses in either real-time or batch. The Address Verification processor is wrapped in an EDQ process – this adds significant capabilities over calling the underlying Address Verification API directly, specifically: Country-specific thresholds to determine when to accept the verification result (and therefore to change the input address) based on the confidence level of the API Optimization of address verification by pre-standardizing data where required Formatting of output addresses into the input address fields normally used by applications Adding descriptions of the address verification and geocoding return codes The process can then be used to provide real-time and batch address cleansing in any application; such as a simple web page calling address cleaning and geocoding as part of a check on individual data.     Duplicate Prevention Unlike Informatica Identity Resolution (IIR), EDQ uses stateless services for duplicate prevention to avoid issues caused by complex replication and synchronization of large volume customer data. When a record is added or updated in an application, the EDQ Cluster Key Generation service is called, and returns a number of key values. These are used to select other records (‘candidates’) that may match in the application data (which has been pre-seeded with keys using the same service). The ‘driving record’ (the new or updated record) is then presented along with all selected candidates to the EDQ Matching Service, which decides which of the candidates are a good match with the driving record, and scores them according to the strength of match. In this model, complex multi-locale EDQ techniques can be used to generate the keys and ensure that the right balance between performance and matching effectiveness is maintained, while ensuring that the application retains control of data integrity and transactional commits. The process is explained below: EDQ Duplicate Prevention Architecture Note that where the integration is with a hub, there may be an additional call to the Cluster Key Generation service if the master record has changed due to merges with other records (and therefore needs to have new key values generated before commit). Batch Matching In order to allow customers to use different match rules in batch to real-time, separate matching templates are provided for batch matching. For example, some customers want to minimize intervention in key user flows (such as adding new customers) in front end applications, but to conduct a more exhaustive match on a regular basis in the back office. The batch matching jobs are also used when migrating data between systems, and in this case normally a more precise (and automated) type of matching is required, in order to minimize the review work performed by Data Stewards.  In batch matching, data is captured into EDQ using its standard interfaces, and records are standardized, clustered and matched in an EDQ job before matches are written out. As with all EDQ jobs, batch matching may be called from Oracle Data Integrator (ODI) if required. When working with Siebel CRM (or master data in Siebel UCM), Siebel’s Data Quality Manager is used to instigate batch jobs, and a shared staging database is used to write records for matching and to consume match results. The CDS batch matching processes automatically adjust to Siebel’s ‘Full Match’ (match all records against each other) and ‘Incremental Match’ (match a subset of records against all of their selected candidates) modes. The Future The Customer Data Services Pack is an important part of the Oracle strategy for EDQ, offering a clear path to making Data Quality Assurance an integral part of enterprise applications, and providing a strong value proposition for adopting EDQ. We are planning various additions and improvements, including: An out-of-the-box Data Quality Dashboard Even more comprehensive international data handling Address search (suggesting multiple results) Integrated address matching The EDQ Customer Data Services Pack is part of the Enterprise Data Quality Media Pack, available for download at http://www.oracle.com/technetwork/middleware/oedq/downloads/index.html.

• jQuery Datatable in MVC &hellip; extended.

  - by Steve Clements

  There are a million plugins for jQuery and when a web forms developer like myself works in MVC making use of them is par-for-the-course!  MVC is the way now, web forms are but a memory!! Grids / tables are my focus at the moment.  I don’t want to get in to righting reems of css and html, but it’s not acceptable to simply dump a table on the screen, functionality like sorting, paging, fixed header and perhaps filtering are expected behaviour.  What isn’t always required though is the massive functionality like editing etc you get with many grid plugins out there. You potentially spend a long time getting everything hooked together when you just don’t need it. That is where the jQuery DataTable plugin comes in.  It doesn’t have editing “out of the box” (you can add other plugins as you require to achieve such functionality). What it does though is very nicely format a table (and integrate with jQuery UI) without needing to hook up and Async actions etc.  Take a look here… http://www.datatables.net I did in the first instance start looking at the Telerik MVC grid control – I’m a fan of Telerik controls and if you are developing an in-house of open source app you get the MVC stuff for free…nice!  Their grid however is far more than I require.  Note: Using Telerik MVC controls with your own jQuery and jQuery UI does come with some hurdles, mainly to do with the order in which all your jQuery is executing – I won’t cover that here though – mainly because I don’t have a clear answer on the best way to solve it! One nice thing about the dataTable above is how easy it is to extend http://www.datatables.net/examples/plug-ins/plugin_api.html and there are some nifty examples on the site already… I however have a requirement that wasn’t on the site … I need a grid at the bottom of the page that will size automatically to the bottom of the page and be scrollable if required within its own space i.e. everything above the grid didn’t scroll as well.  Now a CSS master may have a great solution to this … I’m not that master and so didn’t! The content above the grid can vary so any kind of fixed positioning is out. So I wrote a little extension for the DataTable, hooked that up to the document.ready event and window.resize event. Initialising my dataTable ( s )… $(document).ready(function () {   var dTable = $(".tdata").dataTable({ "bPaginate": false, "bLengthChange": false, "bFilter": true, "bSort": true, "bInfo": false, "bAutoWidth": true, "sScrollY": "400px" });   My extension to the API to give me the resizing….   // ********************************************************************** // jQuery dataTable API extension to resize grid and adjust column sizes // $.fn.dataTableExt.oApi.fnSetHeightToBottom = function (oSettings) { var id = oSettings.nTable.id; var dt = $("#" + id); var top = dt.position().top; var winHeight = $(document).height(); var remain = (winHeight - top) - 83; dt.parent().attr("style", "overflow-x: auto; overflow-y: auto; height: " + remain + "px;"); this.fnAdjustColumnSizing(); } This is very much is debug mode, so pretty verbose at the moment – I’ll tidy that up later! You can see the last call is a call to an existing method, as the columns are fixed and that normally involves so CSS voodoo, a call to adjust those sizes is required. Just above is the style that the dataTable gives the grid wrapper div, I got that from some firebug action and stick in my new height. The –83 is to give me the space at the bottom i require for fixed footer!   Finally I hook that up to the load and window resize.  I’m actually using jQuery UI tabs as well, so I’ve got that in the open event of the tabs.   $(document).ready(function () { var oTable; $("#tabs").tabs({ "show": function (event, ui) { oTable = $('div.dataTables_scrollBody>table.tdata', ui.panel).dataTable(); if (oTable.length > 0) { oTable.fnSetHeightToBottom(); } } }); $(window).bind("resize", function () { oTable.fnSetHeightToBottom(); }); }); And that all there is too it.  Testament to the wonders of jQuery and the immense community surrounding it – to which I am extremely grateful. I’ve also hooked up some custom column filtering on the grid – pretty normal stuff though – you can get what you need for that from their website.  I do hide the out of the box filter input as I wanted column specific, you need filtering turned on when initialising to get it to work and that input come with it!  Tip: fnFilter is the method you want.  With column index as a param – I used data tags to simply that one.

• RIDC Accelerator for Portal

  - by Stefan Krantz

  What is RIDC?Remote IntraDoc Client is a Java enabled API that leverages simple transportation protocols like Socket, HTTP and JAX/WS to execute content service operations in WebCenter Content Server. Each operation by design in the Content Server will execute stateless and return a complete result of the request. Each request object simply specifies the in a Map format (key and value pairs) what service to call and what parameters settings to apply. The result responded with will be built on the same Map format (key and value pairs). The possibilities with RIDC is endless since you can consume any available service (even custom made ones), RIDC can be executed from any Java SE application that has any WebCenter Content Services needs. WebCenter Portal and the example Accelerator RIDC adapter frameworkWebCenter Portal currently integrates and leverages WebCenter Content Services to enable available use cases in the portal today, like Content Presenter and Doc Lib. However the current use cases only covers few of the scenarios that the Content Server has to offer, in addition to the existing use cases it is not rare that the customer requirements requires additional steps and functionality that is provided by WebCenter Content but not part of the use cases from the WebCenter Portal.The good news to this is RIDC, the second good news is that WebCenter Portal already leverages the RIDC and has a connection management framework in place. The million dollar question here is how can I leverage this infrastructure for my custom use cases. Oracle A-Team has during its interactions produced a accelerator adapter framework that will reuse and leverage the existing connections provisioned in the webcenter portal application (works for WebCenter Spaces as well), as well as a very comprehensive design patter to minimize the work involved when exposing functionality. Let me introduce the RIDCCommon framework for accelerating WebCenter Content consumption from WebCenter Portal including Spaces. How do I get started?Through a few easy steps you will be on your way, Extract the zip file RIDCCommon.zip to the WebCenter Portal Application file structure (PortalApp) Open you Portal Application in JDeveloper (PS4/PS5) select to open the project in your application - this will add the project as a member of the application Update the Portal project dependencies to include the new RIDCCommon project Make sure that you WebCenter Content Server connection is marked as primary (a checkbox at the top of the connection properties form) You should by this stage have a similar structure in your JDeveloper Application Project Portal Project PortalWebAssets Project RIDCCommon Since the API is coming with some example operations that has already been exposed as DataControl actions, if you open Data Controls accordion you should see following: How do I implement my own operation? Create a new Java Class in for example com.oracle.ateam.portal.ridc.operation call it (GetDocInfoOperation) Extend the abstract class com.oracle.ateam.portal.ridc.operation.RIDCAbstractOperation and implement the interface com.oracle.ateam.portal.ridc.operation.IRIDCOperation The only method you actually are required to implement is execute(RIDCManager, IdcClient, IdcContext) The best practice to set object references for the operation is through the Constructor, example below public GetDocInfoOperation(String dDocName)By leveraging the constructor you can easily force the implementing class to pass right information, you can also overload the Constructor with more or less parameters as required Implement the execute method, the work you supposed to execute here is creating a new request binder and retrieve a response binder with the information in the request binder.In this case the dDocName for which we want the DocInfo Secondly you have to process the response binder by extracting the information you need from the request and restore this information in a simple POJO Java BeanIn the example below we do this in private void processResult(DataBinder responseData) - the new SearchDataObject is a Member of the GetDocInfoOperation so we can return this from a access method. Since the RIDCCommon API leverage template pattern for the operations you are now required to add a method that will enable access to the result after the execution of the operationIn the example below we added the method public SearchDataObject getDataObject() - this method returns the pre processed SearchDataObject from the execute method  This is it, as you can see on the code below you do not need more than 32 lines of very simple code 1: public class GetDocInfoOperation extends RIDCAbstractOperation implements IRIDCOperation { 2: private static final String DOC_INFO_BY_NAME = "DOC_INFO_BY_NAME"; 3: private String dDocName = null; 4: private SearchDataObject sdo = null; 5: 6: public GetDocInfoOperation(String dDocName) { 7: super(); 8: this.dDocName = dDocName; 9: } 10:   11: public boolean execute(RIDCManager manager, IdcClient client, 12: IdcContext userContext) throws Exception { 13: DataBinder dataBinder = createNewRequestBinder(DOC_INFO_BY_NAME); 14: dataBinder.putLocal(DocumentAttributeDef.NAME.getName(), dDocName); 15: 16: DataBinder responseData = getResponseBinder(dataBinder); 17: processResult(responseData); 18: return true; 19: } 20: 21: private void processResult(DataBinder responseData) { 22: DataResultSet rs = responseData.getResultSet("DOC_INFO"); 23: for(DataObject dobj : rs.getRows()) { 24: this.sdo = new SearchDataObject(dobj); 25: } 26: super.setMessage(responseData.getLocal(ATTR_MESSAGE)); 27: } 28: 29: public SearchDataObject getDataObject() { 30: return this.sdo; 31: } 32: } How do I execute my operation? In the previous section we described how to create a operation, so by now you should be ready to execute the operation Step one either add a method to the class  com.oracle.ateam.portal.datacontrol.ContentServicesDC or a class of your own choiceRemember the RIDCManager is a very light object and can be created where needed Create a method signature look like this public SearchDataObject getDocInfo(String dDocName) throws Exception In the method body - create a new instance of GetDocInfoOperation and meet the constructor requirements by passing the dDocNameGetDocInfoOperation docInfo = new GetDocInfoOperation(dDocName) Execute the operation via the RIDCManager instance rMgr.executeOperation(docInfo) Return the result by accessing it from the executed operationreturn docInfo.getDataObject() 1: private RIDCManager rMgr = null; 2: private String lastOperationMessage = null; 3:   4: public ContentServicesDC() { 5: super(); 6: this.rMgr = new RIDCManager(); 7: } 8: .... 9: public SearchDataObject getDocInfo(String dDocName) throws Exception { 10: GetDocInfoOperation docInfo = new GetDocInfoOperation(dDocName); 11: boolean boolVal = rMgr.executeOperation(docInfo); 12: lastOperationMessage = docInfo.getMessage(); 13: return docInfo.getDataObject(); 14: }   Get the binaries! The enclosed code in a example that can be used as a reference on how to consume and leverage similar use cases, user has to guarantee appropriate quality and support.  Download link: https://blogs.oracle.com/ATEAM_WEBCENTER/resource/stefan.krantz/RIDCCommon.zip RIDC API Referencehttp://docs.oracle.com/cd/E23943_01/apirefs.1111/e17274/toc.htm

• Unique Business Value vs. Unique IT

  - by barry.perkins

  When the age of computing started, technology was new, exciting, full of potential and had a long way to grow. Vendor architectures were proprietary, and limited in function at first, growing in capability and complexity over time. There were few if any "standards", let alone "open standards" and the concepts of "open systems", and "open architectures" were far in the future. Companies employed intelligent, talented and creative people to implement the best possible solutions for their company. At first, those solutions were "unique" to each company. As time progressed, standards emerged, companies shared knowledge, business capability supplied by technology grew, and companies continued to expand their use of technology. Taking advantage of change required companies to struggle through periodic "revolutionary" change cycles, struggling through costly changes that were fraught with risk, resulted in solutions with an increasingly shorter half-life, and frequently required altering existing business processes and retraining employees and partner businesses. The pace of technological invention and implementation grew at an ever increasing rate, making the "revolutionary" approach based upon "proprietary" or "closed" architectures or technologies no longer viable. Concurrent with the advancement of technology, the rate of change in business increased, leading us to the incredibly fast paced, highly charged, and competitive global economy that we have today, where the most successful companies are companies that are good at implementing, leveraging and exploiting change. Fast forward to today, a world where dramatic changes in business and technology happen continually, a world where "evolutionary" change is crucial. Companies can no longer afford to build "unique IT", nor can they afford regular intervals of "revolutionary" change, with the associated costs and risks. Human ingenuity was once again up to the task, turning technology into a platform supporting business through evolutionary change, by employing "open": open standards; open systems; open architectures; and open solutions. Employing "open", enables companies to implement systems based upon technology, capability and standards that will evolve over time, providing a solid platform upon which a company can drive business needs, requirements, functions, and processes down into the technology, rather than exposing technology to the business, allowing companies to focus on providing "unique business value" rather than "unique IT". The big question! Does moving from "older" technology that no longer meets the needs of today's business, to new "open" technology require yet another "revolutionary change"? A "revolutionary" change with a short half-life, camouflaging reality with great marketing? The answer is "perhaps". With the endless options available to choose from, it is entirely possible to implement a solution that may work well today, but in 5 years time will become yet another albatross for the company to bear. Some solutions may look good today, solving a budget challenge by reducing cost, or solving a specific tactical challenge, but result in highly complex environments, that may be difficult to manage and maintain and limit the future potential of your business. Put differently, some solutions might push today's challenge into the future, resulting in a more complex and expensive solution. There is no such thing as a "1 size fits all" IT solution for business. If all companies implemented business solutions based upon technology that required, or forced the same business processes across all businesses in an industry, it would be extremely difficult to show competitive advantage through "unique business value". It would be equally difficult to "evolve" to meet or exceed business needs and keep up with today's rapid pace of change. How does one ensure that they do not jump from one trap directly into another? Or to put it positively, there are solutions available today that can address these challenges and issues. How does one ensure that the buying decision of today will serve the business well for years into the future? Intelligent & Informed decisions - "buying right" In a previous blog entry, we discussed the value of linking tactical to strategic The key is driving the focus to what is best for your business, handling today's tactical issues while also aligning with a roadmap/strategy that is tightly aligned with your strategic business objectives. When considering the plethora of possible options that provide various approaches to solving today's complex business problems, it is extremely important to ensure that vendors supplying those options, focus on what is best for your business, supplying sufficient information, providing adequate answers to questions, addressing challenges, issues, concerns and objections honestly and openly, and focus on supplying solutions that are tailored for, and deliver the most business value possible for your business. Here are a few questions to consider relative to the proposed options that should help ensure that today's solution doesn't become tomorrow's problem. Do the proposed solutions: Solve the problem(s) you are trying to address? Provide a solid foundation upon which to grow/enhance your business? Provide tactical gains that align with and enable your strategic business goals/objectives? Provide an infrastructure that can be leveraged with subsequent projects? Solve problems for the business overall, the lines of business, or just IT? Simplify your current environment Provide the basis for business: Efficiency Agility Clarity governance, risk, compliance real time business visibility and trend analysis Does your IT staff have the knowledge/experience to successfully manage the proposed systems once they are deployed in production? Done well, you will be presented with options tailored to your business, that enable you to drive the "unique business value" necessary to help your business stand out from others, creating a distinct competitive advantage, delivering what your customers need, when they need it, so you can attract new customers, new business, and grow top line revenue, all at a cost that provides a strong Return on Investment/Return on Assets. The net result is growth with managed cost providing significantly improved profit margin and shareholder value.

The company has 10 manufacturing facilities in United States and window and door showrooms across the United States and Canada. In-home consultations are an important part of Pella’s sales process. Several years ago, the company launched an online appointment scheduling tool to improve customer convenience. While the functionality worked well, the company wanted to increase online conversion rates and decrease the number of incomplete, online appointment schedules. It also wanted to give its business analysts and other line-of-business personnel the ability to update the scheduling tool and interface quickly, without needing IT team intervention and recoding, to better capitalize on opportunities and personalize the interface for specific markets. Pella also looked to reduce IT complexity by selecting a system that integrated easily with its Oracle E-Business Suite Release 12.1 enterprise applications.Pella, which has a large Oracle footprint, selected Oracle WebCenter Sites as the foundation for its new, real-time appointment scheduling application. It used the solution to re-engineer the scheduling process and the information required to set up an appointment. Just a few months after launch, it is seeing improvement in the number of appointments booked online and experiencing fewer abandoned appointments during the scheduling process. As important, Pella can now quickly and easily make changes to images, video, and content displayed on the scheduling tool interface, delivering greater business agility. Previously, such changes required a developer and weeks of coding and testing. Today, a member of Pella’s business analyst team can complete the changes in hours. This capability enables Pella to personalize the Web experience for customers. For example, it can display different products or images for clients in different regions.The solution is also highly scalable. Pella is using Oracle WebCenter Sites for appointment scheduling now and plans to migrate Pella.com, its configurator tool, and dealer microsites onto the platform. Further, Pella plans to leverage the solution to optimize mobile devices. “Moving ahead, we expect to extensively leverage Oracle WebCenter Sites to gain greater flexibility in updating the Web experience, thanks to the ability to make updates quickly without developer resources. Segmentation and targeting capabilities will allow us to create a more personalized experience across both traditional and mobile platforms,” said Teri Lancaster, IT manager, customer experience applications, Pella Corporation. A word from Pella Corporation "Oracle WebCenter Sites?from the start?delivered important benefits. We’ve redesigned the online scheduling process and are seeing more potential customers completing consultation bookings online. More important, the solution opens a world of other possibilities as we plan to migrate Pella.com and our dealer microsites to the platform, and leverage it to optimize the Web experience for our mobile devices.” – Teri Lancaster, IT Manager, Customer Experience Applications, Pella Corporation Oracle Product and Services Oracle WebCenter Sites Why Oracle Pella has a long-standing relationship with Oracle. “We look to Oracle first for a solution. Our Oracle account team came to us with several solutions, and Oracle WebCenter Sites delivered the scalability, ease-of-use, flexibility, and scalability that we required for the appointment scheduling initiative and other Web projects on the horizon, including migrating Pella.com and optimizing our site for mobile platforms,”said Teri Lancaster, IT manager, customer experience applications, Pella Corporation. Implementation Process The Pella implementation team, working with Oracle partner Element Solutions, LLC, integrated the appointment setting application with Pella.com as well as the company’s Oracle E-Business Suite customer relationship management applications. Using Oracle WebCenter Site’s development tools and subversion capabilities to develop the application, the Element Solutions and Pella teams could work remotely and collaboratively, accelerating deployment. Pella went live with the new scheduling tool in just six months. Partner Oracle PartnerElement Solutions, LLC Element Solutions was instrumental at every major stage of the project, including design creation and approval, development, training, and rollout. “Element Solutions was a vital partner for our Oracle WebCenter Sites initiative. The team provided guidance, and more important, critical knowledge transfer at every stage?which equipped us to get the most out of this powerful and versatile solution. We were definitely collaboration partners,” Lancaster said.

• Playing with aspx page cycle using JustMock

  - by mehfuzh

  In this post , I will cover a test code that will mock the various elements needed to complete a HTTP page request and  assert the expected page cycle steps. To begin, i have a simple enumeration that has my predefined page steps: public enum PageStep {     PreInit,     Load,     PreRender,     UnLoad } Once doing so, i  first created the page object [not mocking]. Page page = new Page(); Here, our target is to fire up the page process through ProcessRequest call, now if we take a look inside the method with reflector.net,  the call trace will go like : ProcessRequest –> ProcessRequestWithNoAssert –> SetInstrinsics –> Finallly ProcessRequest. Inside SetInstrinsics ,  it requires calls from HttpRequest, HttpResponse and HttpBrowserCababilities. Using this clue at hand, we can easily know the classes / calls  we need to mock in order to get through the expected call. Accordingly, for  HttpBrowserCapabilities our required mock code will look like: var browser = Mock.Create<HttpBrowserCapabilities>(); // Arrange Mock.Arrange(() => browser.PreferredRenderingMime).Returns("text/html"); Mock.Arrange(() => browser.PreferredResponseEncoding).Returns("UTF-8"); Mock.Arrange(() => browser.PreferredRequestEncoding).Returns("UTF-8"); Now, HttpBrowserCapabilities is get though [Instance]HttpRequest.Browser. Therefore, we create the HttpRequest mock: var request = Mock.Create<HttpRequest>(); Then , add the required get call : Mock.Arrange(() => request.Browser).Returns(browser); As, [instance]Browser.PerferrredResponseEncoding and [instance]Browser.PreferredResponseEncoding  are also set to the request object and to make that they are set properly, we can add the following lines as well [not required though]. bool requestContentEncodingSet = false; Mock.ArrangeSet(() => request.ContentEncoding = Encoding.GetEncoding("UTF-8")).DoInstead(() =>  requestContentEncodingSet = true); Similarly, for response we can write:  var response = Mock.Create<HttpResponse>();    bool responseContentEncodingSet = false;  Mock.ArrangeSet(() => response.ContentEncoding = Encoding.GetEncoding("UTF-8")).DoInstead(() => responseContentEncodingSet = true); Finally , I created a mock of HttpContext and set the Request and Response properties that will returns the mocked version. var context = Mock.Create<HttpContext>();   Mock.Arrange(() => context.Request).Returns(request); Mock.Arrange(() => context.Response).Returns(response); As, Page internally calls RenderControl method , we just need to replace that with our one and optionally we can check if  invoked properly: bool rendered = false; Mock.Arrange(() => page.RenderControl(Arg.Any<HtmlTextWriter>())).DoInstead(() => rendered = true); That’s  it, the rest of the code is simple,  where  i asserted the page cycle with the PageSteps that i defined earlier: var pageSteps = new Queue<PageStep>();   page.PreInit +=delegate { pageSteps.Enqueue(PageStep.PreInit); }; page.Load += delegate { pageSteps.Enqueue(PageStep.Load); }; page.PreRender += delegate { pageSteps.Enqueue(PageStep.PreRender);}; page.Unload +=delegate { pageSteps.Enqueue(PageStep.UnLoad);};   page.ProcessRequest(context);   Assert.True(requestContentEncodingSet); Assert.True(responseContentEncodingSet); Assert.True(rendered);   Assert.Equal(pageSteps.Dequeue(), PageStep.PreInit); Assert.Equal(pageSteps.Dequeue(), PageStep.Load); Assert.Equal(pageSteps.Dequeue(), PageStep.PreRender); Assert.Equal(pageSteps.Dequeue(), PageStep.UnLoad);   Mock.Assert(request); Mock.Assert(response); You can get the test class shown in this post here to give a try by yourself with of course JustMock :-).

• Killing Stuck Child JVM's

  - by ACShorten

  Note: This facility only applies to Oracle Utilities Application Framework products using COBOL. In some situations, the Child JVM's may spin. This causes multiple startup/shutdown Child JVM messages to be displayed and recursive child JVM's to be initiated and shunned. If the following: Unable to establish connection on port …. after waiting .. seconds.The issue can be caused intermittently by CPU spins in connection to the creation of new processes, specifically Child JVMs. Recursive (or double) invocation of the System.exit call in the remote JVM may be caused by a Process.destroy call that the parent JVM always issues when shunning a JVM. The issue may happen when the thread in the parent JVM that is responsible for the recycling gets stuck and it affects all child JVMs. If this issue occurs at your site then there are a number of options to address the issue: Configure an Operating System level kill command to force the Child JVM to be shunned when it becomes stuck. Configure a Process.destroy command to be used if the kill command is not configured or desired. Specify a time tolerance to detect stuck threads before issuing the Process.destroy or kill commands. Note: This facility is also used when the Parent JVM is also shutdown to ensure no zombie Child JVM's exit. The following additional settings must be added to the spl.properties for the Business Application Server to use this facility: spl.runtime.cobol.remote.kill.command – Specify the command to kill the Child JVM process. This can be a command or specify a script to execute to provide additional information. The kill.command property can accept two arguments, {pid} and {jvmNumber}, in the specified string. The arguments must be enclosed in curly braces as shown here. Note: The PID will be appended to the killcmd string, unless the {pid} and {jvmNumber} arguments are specified. The jvmNumber can be useful if passed to a script for logging purposes. Note: If a script is used it must be in the path and be executable by the OS user running the system. spl.runtime.cobol.remote.destroy.enabled – Specify whether to use the Process.destroy command instead of the kill command. Specify true or false. Default value is false. Note: Unless otherwise required, it is recommended to use the kill command option if shunning JVM's is an issue. There this value can remain its default value, false, unless otherwise required. spl.runtime.cobol.remote.kill.delaysecs – Specify the number of seconds to wait for the Child JVM to terminate naturally before issuing the Process.destroy or kill commands. Default is 10 seconds. For example: spl.runtime.cobol.remote.kill.command=kill -9 {pid} {jvmNumber}spl.runtime.cobol.remote.destroy.enabled=falsespl.runtime.cobol.remote.kill.delaysecs=10 When a Child JVM is to be recycled, these properties are inspected and the spl.runtime.cobol.remote.kill.command, executed if provided. This is done after waiting for spl.runtime.cobol.remote.kill.delaysecs seconds to give the JVM time to shut itself down. The spl.runtime.cobol.remote.destroy.enabled property must be set to true AND the spl.runtime.cobol.remote.kill.command omitted for the original Process.destroy command to be used on the process. Note: By default the spl.runtime.cobol.remote.destroy enabled is set to false and is therefore disabled. If neither spl.runtime.cobol.remote.kill.command nor spl.runtime.cobol.remote.destroy.enabled is specified, child JVMs will not beforcibly killed. They will be left to shut themselves down (which may lead to orphan JVMs). If both are specified, the spl.runtime.cobol.remote.kill.command is preferred and spl.runtime.cobol.remote.destroy.enabled defaulted to false.It is recommended to invoke a script to issue the direct kill command instead of directly using the kill -9 commands.For example, the following sample script ensures that the process Id is an active cobjrun process before issuing the kill command: forcequit.sh #!/bin/shTHETIME=`date +"%Y-%m-%d %H:%M:%S"`if [ "$1" = "" ]then  echo "$THETIME: Process Id is required" >>$SPLSYSTEMLOGS/forcequit.log  exit 1fijavaexec=cobjrunps e $1 | grep -c $javaexecif [ $? = 0 ]then  echo "$THETIME: Process $1 is an active $javaexec process -- issuing kill-9 $1" >>$SPLSYSTEMLOGS/forcequit.log  kill -9 $1exit 0else  echo "$THETIME: Process id $1 is not a $javaexec process or not active --  kill will not be issued" >>$SPLSYSTEMLOGS/forcequit.logexit 1fi This script's name would then be specified as the value for the spl.runtime.cobol.remote.kill.command property, for example: spl.runtime.cobol.remote.kill.command=forcequit.sh The forcequit script does not have any explicit parameters but pid is passed automatically. To use the jvmNumber parameter it must explicitly specified in the command. For example, to call script forcequit.sh and pass it the pid and the child JVM number, specify it as follows: spl.runtime.cobol.remote.kill.command=forcequit.sh {pid} {jvmNumber} The script can then use the JVM number for logging purposes or to further ensure that the correct pid is being killed.If the arguments are omitted, the pid is automatically appended to the spl.runtime.cobol.remote.kill.command string. To use this facility the following patches must be installed: Patch 13719584 for Oracle Utilities Application Framework V2.1, Patches 13684595 and 13634933 for Oracle Utilities Application Framework V2.2 Group Fix 4 (as Patch 13640668) for Oracle Utilities Application Framework V4.1.

• Allowing Access to HttpContext in WCF REST Services

  - by Rick Strahl

  If you’re building WCF REST Services you may find that WCF’s OperationContext, which provides some amount of access to Http headers on inbound and outbound messages, is pretty limited in that it doesn’t provide access to everything and sometimes in a not so convenient manner. For example accessing query string parameters explicitly is pretty painful: [OperationContract] [WebGet] public string HelloWorld() { var properties = OperationContext.Current.IncomingMessageProperties; var property = properties[HttpRequestMessageProperty.Name] as HttpRequestMessageProperty; string queryString = property.QueryString; var name = StringUtils.GetUrlEncodedKey(queryString,"Name"); return "Hello World " + name; } And that doesn’t account for the logic in GetUrlEncodedKey to retrieve the querystring value. It’s a heck of a lot easier to just do this: [OperationContract] [WebGet] public string HelloWorld() { var name = HttpContext.Current.Request.QueryString["Name"] ?? string.Empty; return "Hello World " + name; } Ok, so if you follow the REST guidelines for WCF REST you shouldn’t have to rely on reading query string parameters manually but instead rely on routing logic, but you know what: WCF REST is a PITA anyway and anything to make things a little easier is welcome. To enable the second scenario there are a couple of steps that you have to take on your service implementation and the configuration file. Add aspNetCompatibiltyEnabled in web.config Fist you need to configure the hosting environment to support ASP.NET when running WCF Service requests. This ensures that the ASP.NET pipeline is fired up and configured for every incoming request. <system.serviceModel>     <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> </system.serviceModel> Markup your Service Implementation with AspNetCompatibilityRequirements Attribute Next you have to mark up the Service Implementation – not the contract if you’re using a separate interface!!! – with the AspNetCompatibilityRequirements attribute: [ServiceContract(Namespace = "RateTestService")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class RestRateTestProxyService Typically you’ll want to use Allowed as the preferred option. The other options are NotAllowed and Required. Allowed will let the service run if the web.config attribute is not set. Required has to have it set. All these settings determine whether an ASP.NET host AppDomain is used for requests. Once Allowed or Required has been set on the implemented class you can make use of the ASP.NET HttpContext object. When I allow for ASP.NET compatibility in my WCF services I typically add a property that exposes the Context and Request objects a little more conveniently: public HttpContext Context { get { return HttpContext.Current; } } public HttpRequest Request { get { return HttpContext.Current.Request; } } While you can also access the Response object and write raw data to it and manipulate headers THAT is probably not such a good idea as both your code and WCF will end up writing into the output stream. However it might be useful in some situations where you need to take over output generation completely and return something completely custom. Remember though that WCF REST DOES actually support that as well with Stream responses that essentially allow you to return any kind of data to the client so using Response should really never be necessary. Should you or shouldn’t you? WCF purists will tell you never to muck with the platform specific features or the underlying protocol, and if you can avoid it you definitely should avoid it. Querystring management in particular can be handled largely with Url Routing, but there are exceptions of course. Try to use what WCF natively provides – if possible as it makes the code more portable. For example, if you do enable ASP.NET Compatibility you won’t be able to self host a WCF REST service. At the same time realize that especially in WCF REST there are number of big holes or access to some features are a royal pain and so it’s not unreasonable to access the HttpContext directly especially if it’s only for read-only access. Since everything in REST works of URLS and the HTTP protocol more control and easier access to HTTP features is a key requirement to building flexible services. It looks like vNext of the WCF REST stuff will feature many improvements along these lines with much deeper native HTTP support that is often so useful in REST applications along with much more extensibility that allows for customization of the inputs and outputs as data goes through the request pipeline. I’m looking forward to this stuff as WCF REST as it exists today still is a royal pain (in fact I’m struggling with a mysterious version conflict/crashing error on my machine that I have not been able to resolve – grrrr…).© Rick Strahl, West Wind Technologies, 2005-2011Posted in ASP.NET  AJAX  WCF

• Justifiable Perks.

  - by Phil Factor

      I was once the director of a start-up IT Company, and had the task of recruiting a proportion of the management team. As my background was in IT management, I was rather more familiar with recruiting Geeks for technology jobs, but here, one of my early tasks was interviewing a Marketing Director.  The small group of financiers had suggested a rather strange Irishman called  Halleran.  From my background in City of London dealing-rooms, I was slightly unprepared for the experience of interviewing anyone wearing a pink suit. Many of my older City colleagues would have required resuscitation after seeing his white leather shoes. However, nobody will accuse me of prejudging an interviewee. After all, many Linux experts who I’ve come to rely on have appeared for interview dressed as hobbits. In fact, the interview went well, and we had even settled his salary.  I was somewhat unprepared for the coda.    ‘And I will need to be provided with a Ferrari  by the company.’    ‘Hmm. That seems reasonable.’    Initially, he looked startled, and then a slow smile of victory spread across his face.    ‘What colour would you like?’ I asked genially.    ‘It has to be red.’ He looked very earnest on this point.    ‘Fine. I have to go past Hamleys on the way home this evening, so I’ll pick one up then for you.’    ‘Er.. Hamley’s is a toyshop, not a Ferrari Dealership.’    I stared at him in bafflement for a few seconds. ‘You’re not seriously asking for a real Ferrari are you?’     ‘Well, yes. Not for my own sake, you understand. I’d much prefer a simple run-about, but my position demands it. How could I maintain the necessary status in the office without one? How could I do my job in marketing when my grey Datsun was all too visible in the car Park? It is a tool of the job.’    ‘Excuse me a moment, but I must confer with the MD’    I popped out to see Chris, the MD. ‘Chris, I’m interviewing a lunatic in a pink suit who is trying to demand that a Ferrari is a precondition of his employment. I tried the ‘misunderstanding trick’ but it didn’t faze him.’     ‘Sorry, Phil, but we’ve got to hire him. The VCs insist on it. You’ve got to think of something that doesn’t involve committing to the purchase of a Ferrari. Current funding barely covers the rent for the building.’    ‘OK boss. Leave it to me.’    On return, I slapped O’Halleran’s file on the table with a genial, paternalistic smile. ‘Of course you should have a Ferrari. The only trouble is that it will require a justification document that can be presented to the board. I’m sure you’ll have no problem in preparing this document in the required format.’ The initial look of despair was quickly followed by a bland look of acquiescence. He had, earlier in the interview, argued with great eloquence his skill in preparing the tiresome documents that underpin the essential corporate and government deals that were vital to the success of this new enterprise. The justification of a Ferrari should be a doddle.     After the interview, Chris nervously asked how I’d fared.     ‘I think it is all solved.’    ‘… without promising a Ferrari, I hope.’    ‘Well, I did actually; on condition he justified it in writing.’    Chris issued a stream of invective. The strain of juggling the resources in an underfunded startup was beginning to show.    ‘Don’t worry. In the unlikely event of him coming back with the required document, I’ll give him mine.’    ‘Yours?’ He strode over to the window to stare down at the car park.    He needn’t have worried: I knew that his breed of marketing man could more easily lay an ostrich egg than to prepare a decent justification document. My Ferrari is still there at the back of my garage. Few know of the Ferrari cultivator, a simple inexpensive motorized device designed for the subsistence farmers of southern Italy. It is the very devil to start, but it creates a perfect tilth for the seedbed.

• Organization &amp; Architecture UNISA Studies &ndash; Chap 5

  - by MarkPearl

  Learning Outcomes Describe the operation of a memory cell Explain the difference between DRAM and SRAM Discuss the different types of ROM Explain the concepts of a hard failure and a soft error respectively Describe SDRAM organization Semiconductor Main Memory The two traditional forms of RAM used in computers are DRAM and SRAM DRAM (Dynamic RAM) Divided into two technologies… Dynamic Static Dynamic RAM is made with cells that store data as charge on capacitors. The presence or absence of charge in a capacitor is interpreted as a binary 1 or 0. Because capacitors have natural tendency to discharge, dynamic RAM requires periodic charge refreshing to maintain data storage. The term dynamic refers to the tendency of the stored charge to leak away, even with power continuously applied. Although the DRAM cell is used to store a single bit (0 or 1), it is essentially an analogue device. The capacitor can store any charge value within a range, a threshold value determines whether the charge is interpreted as a 1 or 0. SRAM (Static RAM) SRAM is a digital device that uses the same logic elements used in the processor. In SRAM, binary values are stored using traditional flip flop logic configurations. SRAM will hold its data as along as power is supplied to it. Unlike DRAM, no refresh is required to retain data. SRAM vs. DRAM DRAM is simpler and smaller than SRAM. Thus it is more dense and less expensive than SRAM. The cost of the refreshing circuitry for DRAM needs to be considered, but if the machine requires a large amount of memory, DRAM turns out to be cheaper than SRAM. SRAMS are somewhat faster than DRAM, thus SRAM is generally used for cache memory and DRAM is used for main memory. Types of ROM Read Only Memory (ROM) contains a permanent pattern of data that cannot be changed. ROM is non volatile meaning no power source is required to maintain the bit values in memory. While it is possible to read a ROM, it is not possible to write new data into it. An important application of ROM is microprogramming, other applications include library subroutines for frequently wanted functions, System programs, Function tables. A ROM is created like any other integrated circuit chip, with the data actually wired into the chip as part of the fabrication process. To reduce costs of fabrication, we have PROMS. PROMS are… Written only once Non-volatile Written after fabrication Another variation of ROM is the read-mostly memory, which is useful for applications in which read operations are far more frequent than write operations, but for which non volatile storage is required. There are three common forms of read-mostly memory, namely… EPROM EEPROM Flash memory Error Correction Semiconductor memory is subject to errors, which can be classed into two categories… Hard failure – Permanent physical defect so that the memory cell or cells cannot reliably store data Soft failure – Random error that alters the contents of one or more memory cells without damaging the memory (common cause includes power supply issues, etc.) Most modern main memory systems include logic for both detecting and correcting errors. Error detection works as follows… When data is to be read into memory, a calculation is performed on the data to produce a code Both the code and the data are stored When the previously stored word is read out, the code is used to detect and possibly correct errors The error checking provides one of 3 possible results… No errors are detected – the fetched data bits are sent out An error is detected, and it is possible to correct the error. The data bits plus error correction bits are fed into a corrector, which produces a corrected set of bits to be sent out An error is detected, but it is not possible to correct it. This condition is reported Hamming Code See wiki for detailed explanation. We will probably need to know how to do a hemming code – refer to the textbook (pg. 188 – 189) Advanced DRAM organization One of the most critical system bottlenecks when using high-performance processors is the interface to main memory. This interface is the most important pathway in the entire computer system. The basic building block of main memory remains the DRAM chip. In recent years a number of enhancements to the basic DRAM architecture have been explored, and some of these are now on the market including… SDRAM (Synchronous DRAM) DDR-DRAM RDRAM SDRAM (Synchronous DRAM) SDRAM exchanges data with the processor synchronized to an external clock signal and running at the full speed of the processor/memory bus without imposing wait states. SDRAM employs a burst mode to eliminate the address setup time and row and column line precharge time after the first access In burst mode a series of data bits can be clocked out rapidly after the first bit has been accessed SDRAM has a multiple bank internal architecture that improves opportunities for on chip parallelism SDRAM performs best when it is transferring large blocks of data serially There is now an enhanced version of SDRAM known as double data rate SDRAM or DDR-SDRAM that overcomes the once-per-cycle limitation of SDRAM

• How to display a dependent list box disabled if no child data exist

  - by frank.nimphius

  A requirement on OTN was to disable the dependent list box of a model driven list of value configuration whenever the list is empty. To disable the dependent list, the af:selectOneChoice component needs to be refreshed with every value change of the parent list, which however already is the case as the list boxes are already dependent. When you create model driven list of values as choice lists in an ADF Faces page, two ADF list bindings are implicitly created in the PageDef file of the page that hosts the input form. At runtime, a list binding is an instance of FacesCtrlListBinding, which exposes getItems() as a method to access a list of available child data (java.util.List). Using Expression Language, the list is accessible with #{bindings.list_attribute_name.items} To dynamically set the disabled property on the dependent af:selectOneChoice component, however, you need a managed bean that exposes the following two methods //empty – but required – setter method public void setIsEmpty(boolean isEmpty) {} //the method that returns true/false when the list is empty or //has values public boolean isIsEmpty() {   FacesContext fctx = FacesContext.getCurrentInstance();   ELContext elctx = fctx.getELContext();   ExpressionFactory exprFactory =                          fctx.getApplication().getExpressionFactory();   ValueExpression vexpr =                       exprFactory.createValueExpression(elctx,                         "#{bindings.EmployeeId.items}",                       Object.class);   List employeesList = (List) vexpr.getValue(elctx);                        return employeesList.isEmpty()? true : false;      } If referenced from the dependent choice list, as shown below, the list is disabled whenever it contains no list data <! --  master list --> <af:selectOneChoice value="#{bindings.DepartmentId.inputValue}"                                  label="#{bindings.DepartmentId.label}"                                  required="#{bindings.DepartmentId.hints.mandatory}"                                   shortDesc="#{bindings.DepartmentId.hints.tooltip}"                                   id="soc1" autoSubmit="true">      <f:selectItems value="#{bindings.DepartmentId.items}" id="si1"/> </af:selectOneChoice> <! --  dependent  list --> <af:selectOneChoice value="#{bindings.EmployeeId.inputValue}"                                   label="#{bindings.EmployeeId.label}"                                      required="#{bindings.EmployeeId.hints.mandatory}"                                   shortDesc="#{bindings.EmployeeId.hints.tooltip}"                                   id="soc2" disabled="#{lovTestbean.isEmpty}"                                   partialTriggers="soc1">     <f:selectItems value="#{bindings.EmployeeId.items}" id="si2"/> </af:selectOneChoice>

• Detecting Duplicates Using Oracle Business Rules

  - by joeywong-Oracle

  Recently I was involved with a Business Process Management Proof of Concept (BPM PoC) where we wanted to show how customers could use Oracle Business Rules (OBR) to easily define some rules to detect certain conditions, such as duplicate account numbers, duplicate names, high transaction amounts, etc, in a set of transactions. Traditionally you would have to loop through the transactions and compare each transaction with each other to find matching conditions. This is not particularly nice as it relies on more traditional approaches (coding) and is not the most efficient way. OBR is a great place to house these types’ of rules as it allows users/developers to externalise the rules, in a simpler manner, externalising the rules from the message flows and allows users to change them when required. So I went ahead looking for some examples. After quite a bit of time spent Googling, I did not find much out in the blogosphere. In fact the best example was actually from...... wait for it...... Oracle Documentation! (http://docs.oracle.com/cd/E28271_01/user.1111/e10228/rules_start.htm#ASRUG228) However, if you followed the link there was not much explanation provided with the example. So the aim of this article is to provide a little more explanation to the example so that it can be better understood. Note: I won’t be covering the BPM parts in great detail. Use case: Payment instruction file is required to be processed. Before instruction file can be processed it needs to be approved by a business user. Before the approval process, it would be useful to run the payment instruction file through OBR to look for transactions of interest. The output of the OBR can then be used to flag the transactions for the approvers to investigate. Example BPM Process So let’s start defining the Business Rules Dictionary. For the input into our rules, we will be passing in an array of payments which contain some basic information for our demo purposes. Input to Business Rules And for our output we want to have an array of rule output messages. Note that the element I am using for the output is only for one rule message element and not an array. We will configure the Business Rules component later to return an array instead. Output from Business Rules Business Rule – Create Dictionary Fill in all the details and click OK. Open the Business Rules component and select Decision Functions from the side. Modify the Decision Function Configuration Select the decision function and click on the edit button (the pencil), don’t worry that JDeveloper indicates that there is an error with the decision function. Then click the Ouputs tab and make sure the checkbox under the List column is checked, this is to tell the Business Rules component that it should return an array of rule message elements. Updating the Decision Service Next we will define the actual rules. Click on Ruleset1 on the side and then the Create Rule in the IF/THEN Rule section. Creating new rule in ruleset Ok, this is where some detailed explanation is required. Remember that the input to this Business Rules dictionary is a list of payments, each of those payments were of the complex type PaymentType. Each of those payments in the Oracle Business Rules engine is treated as a fact in its working memory. Implemented rule So in the IF/THEN rule, the first task is to grab two PaymentType facts from the working memory and assign them to temporary variable names (payment1 and payment2 in our example). Matching facts Once we have them in the temporary variables, we can then start comparing them to each other. For our demonstration we want to find payments where the account numbers were the same but the account name was different. Suspicious payment instruction And to stop the rule from comparing the same facts to each other, over and over again, we have to include the last test. Stop rule from comparing endlessly And that’s it! No for loops, no need to keep track of what you have or have not compared, OBR handles all that for you because everything is done in its working memory. And once all the tests have been satisfied we need to assert a new fact for the output. Assert the output fact Save your Business Rules. Next step is to complete the data association in the BPM process. Pay extra care to use Copy List instead of the default Copy when doing data association at an array level. Input and output data association Deploy and test. Test data Rule matched Parting words: Ideally you would then use the output of the Business Rules component to then display/flag the transactions which triggered the rule so that the approver can investigate.

• Easing the Journey to the Private Cloud with Oracle Consulting

  - by MichaelM-Oracle

  By Sanjai Marimadaiah, Senior Director, Strategy & Business Development – Cloud Solutions, Oracle Consulting Services Business leaders are now leading the charge on how their firms can profit from cloud solutions. Agility and innovation are becoming the primary drivers of the business case for the cloud, even more than the anticipated cost savings. Leaders need to find the right strategy and optimize the use of cloud-based applications across their enterprise-computing infrastructure. The Problem – Current State With prevalent IT practices, many organizations find that they run multiple IT solutions serving similar business needs. This has led to the proliferation of technology stacks, for example: Oracle 10g on Sun T4 running Solaris 9; Oracle 11g on Exadata running Linux; or Oracle 12c on commodity x86 servers. This variance has a huge impact on an organization’s agility and expenses, and requires IT professionals with varied skills as well as on-going training for different systems and tools. Fortunately there is a practical business strategy to overcome this unneeded redundancy. Thus begins a journey to the right cloud computing solution. The Solution – Cloud Services from Oracle Consulting Services (OCS) Oracle Consulting Services (OCS ) works closely with our clients as trusted advisors to proactively respond to business needs and IT concerns. OCS understands that making the transition to cloud solutions begins with a strategic conversation, based on its deep expertise for successfully completing private cloud service engagements with several companies. For a journey to the cloud, Oracle Consulting Services leads the client through four phases– standardization, consolidation, service delivery, and enterprise cloud – to achieve optimal returns. Phase 1 - Standardization Oracle Consulting Services (OCS) works with clients to evaluate their business requirements and propose a set of standard solutions stacks for various IT solutions. This is an opportune time to evaluate cloud ready solutions, such as Oracle 12c, Oracle Exadata, and the Oracle Database Appliance (ODA). The OCS consultants, together with the delivery team, then turn to upgrading and migrating existing solution stacks to standardized offerings. OCS has the expertise and tools to complete this stage in a fraction of the time required by other IT services companies. Clients quickly realize cost savings in tools, processes, and type/number of resources required. This standardization also improves agility of the IT organizations and their abilities to respond to the needs of various business units. Phase 2 - Consolidation During the consolidation phase, OCS consultants programmatically consolidate hundreds of databases into a smaller number of servers to improve utilization, reduce floor space, and optimize maintenance costs. Consolidation helps clients realize huge savings in CapEx investments and shrink OpEx costs. The use of engineered systems, such as Oracle Exadata, greatly reduces the client’s risk of moving to a new solution stack. OCS recommends clients to pursue Phase 1 (Standardization) and Phase 2 (Consolidation) simultaneously to reduce the overall time, effort, and expense of the cloud journey. Phase 3 - Service Delivery Once a client is on a path of standardization and consolidation, OCS consultants create Service Catalogues based on the SLAs requirements and the criticality of the solutions. The number and types of Service Catalogues (Platinum, Gold, Silver, Bronze, etc.) vary from client to client. OCS consultants also implement a variety of value-added cloud solutions, including monitoring, metering, and charge-back solutions. At this stage, clients are able to achieve a high level of understanding in their cloud journey. Their IT organizations are operating efficiently and are more agile in responding to the needs of business units. Phase 4 - Enterprise Cloud In the final phase of the cloud journey, the economics of the IT organizations change. Business units can request services on-demand; applications can be deployed and consumed on a pay-as-you-go model. OCS has the expertise and capabilities to establish processes, programs, and solutions required for IT organizations to transform how they interact with business units. The Promise of Cloud Solutions Depending the size and complexity of their business model, some clients are able to abbreviate some phases of their cloud journey. Cloud solutions are still evolving and there is rapid pace of innovation to transform how IT organizations operate. The lesson is clear. Cloud solutions hold a lot of promise for business agility. Business leaders can now leverage an additional set of capabilities and services. They can ramp up their pace of innovation. With cloud maturity, they can compete more effectively in their respective markets. But there are certainly challenges ahead. A skilled consulting services partner can play a pivotal role as a trusted advisor in the successful adoption of cloud solutions. Oracle Consulting Services has expertise and a portfolio of services to help clients succeed on their journey to the cloud.
