• Deploying to a clustered weblogic application server or Red Hat Linux

  - by user510210

  I am developing an application with following software stack: XHTML / CSS / ExtJS / DWR / Javascript (Presentation Layer) EJB 3.0 / Spring MVC Hibernate / Hibernate Spatial My application works well in a single server development environment. But deploying to clustered weblogic environment on Red Hat does not work and results in the following exception:

• Single device that can work as tablet and as desktop PC

  - by flow

  I have a macbook pro and an iPad 2. I tried to use iPad 2 for work when I am out of the office but this is not very comfortable since one has to sync documents, not all Os X Lion apps exist for iPad 2 and so on. I think a solution would be a single tablet device that at the office can be connected to some dock station and then I have the equivalent of my macbook, but when I am out of the office I can touch the screen and used the same applications while on the road. As far as I know the iPad 2 does not and will not allow this. Therefore I wonder if you could recommend me another hardware/tablet/etc that could work this way now as of March 2012.

• Setting up podcasting for a non-tech user

  - by Force Flow

  I have a user who wants to start making podcasts, but they only have basic skills when it comes to technology. So, I was trying to get a process together that would be easy for them to follow. To upload files (the mp3's and rss feed files), I have an explorer shortcut for their FTP space. To record the podcast, I was going to either use audacity or PodProducer. For the RSS feed, I was looking for a podcast RSS generator of some sort. In my search for this, I've come across a lot of dead links and a lot of paid tools, so I haven't come up with anything too useful. Is there a free, reliable webservice or windows-based tool available that folks like to use?

• Can't insert cells in Excel 2010 - "operation not allowed" error message

  - by Force Flow

  I was working on a spreadsheet in Excel 2010, and all of a sudden when I attempted to insert a new row of cells, I saw that the insert and delete options were grayed out. I attempted to copy a different row and insert it as a new row, but I got the error message: "This operation is not allowed. The operation is attempting to shift cells in a table on your worksheet." I have not merged or hidden any cells/rows/columns. There are no formulas. There is no data verification. I tried closing and re-opening the spreadsheet. Searching for answers brings up nothing useful.

• task scheduler - run interactively as any user with admin credentials

  - by Force Flow

  I'm trying to deploy a scheduled task with a GPO. The task is set to run at login and executes a batch file, which then executes an EXE file. However, I also need it to be interactive and run with admin privledges to bypass the UAC prompt for a username and password when the exe file runs. I created the task for "Vista and later". I've tried running the task as mydoman\administrator and as NT AUTHORITY\Authenticated users with "run only when user is logged in" and "run with highest privledges" selected. If I log in as anyone but administrator, the task does run in the background, as I can see the cmd.exe process running in task manager as mydomain\administrator. Only if I log in as administrator do I then see the cmd window with the batch script running. How can I get the cmd window to display no matter which user logs in?

• After returning from standby mode, win7 asks for login twice

  - by Force Flow

  When a Windows 7 32-bit PC attached to a domain comes back from standby mode and has no user logged in, if I log in once, it jumps back to the login screen. If I log in for a second time, then it actually logs in. This happens on multiple PCs, and is not a hardware issue. The PCs are also free of viruses/malware, and are otherwise problem-free. Why does it do this, and is there a way to prevent this annoyance?

• Java Web App: Passing form parameters across multiple pages

  - by digiarnie

  Hi, what is the best practice or best way of passing form parameters from page to page in a flow? If I have a flow where a user enters data in a form and hits next and repeats this process until they get to an approval page, what ways could I approach this problem to make the retention of data as simple as possible over the flow? I guess you could put all the information as you go in the session but could you get into memory issues if a lot of people are using your app and going through the flow at the same time?

• MSSQL 2008 login failed for windows authentication

  - by Force Flow

  I'm running Microsoft SQL 2008 on a Windows 2008 Server. The MSSQL server server authentication is set to SQL Server and Windows Authentication mode. I have created an active directory security group "xyz app users". I have added a normal user (without any active directory admin privledges) and a user with domain admin privledges to the "xyz app users" group. I have added the group to the MSSQL management console as a login user. This group is a member of the public server role and is mapped to two databases. On a workstation, when the normal user is logged in, I configure a DSN ODBC connection, and I'm able to successfully create the DSN and test the SQL connection. However, when I'm logged in as the user with domain admin privledges, when I attempt to configure the DSN ODBC connection, I can't get past the login ID configuration screen. If I select "windows authentication" and click "next", I get an error: Connection failed: SQLState: '28000' SQL Server Error: 18456 [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'mydomain\myuser' On the server's application event logs, this error appears: Login failed for user 'mydomain\myuser'. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: 172.x.x.x] And in MSSQL's event logs: Error: 18456, Severity: 14, State: 11 Solutions that I've seen so far do not seem to fit this situation (some solutions I've seen are only applicable when the BUILDIN\Administrator is being used locally on the server, which is not the case here).

• How to efficiently restore Library folder partially deleted on OS X

  - by flow

  I am using OS X Lion, and trying to delete some files I did accidentally (from home directoy): rm -fr Library I realized about this some 15 seconds later and did killall rm Some folders have been deleted, of course, inside "Library". Now the system seems to be ok, but I fear what will happen in case of reboot. I have a Time Machine backup from 5 days ago. I wonder if it would be a good solution, just to copy whole "Library" folder from my home directory from backup and replace this one. Or, what do you think would be the best approach? PS: In order to restore just deleted directories inside "Library", in which order does "rm" start to delete directories, alphabetically?

• IIS7.5 website (mostly) inaccessible from the outside world

  - by Force Flow

  On the network firewall, I opened up port 80 and forwarded it to the Windows Server 2008 R2 running IIS 7.5. Port 80 is open in the Windows firewall. On the LAN, the website is accessible without any trouble. When accessed from the outside, I can access it only 3 times every few hours before access to it cuts out from the outside. There aren't any access limits in IIS or the network's firewall as far as I can tell. IIS is running PHP 5.3. The default website has been deleted. The bindings for the website's domain are set for mydomain.com *:80 and mydomain.com 192.168.0.3:80

• Send emails in a non-interactive way in OS X

  - by flow

  I am using Mail.app in OS X 10.7. In a text file I have a list with 500 different email addresses, extracted from my address book, each one in a different line. I would like to send some christmas. So I prepared a text template and I would like to send same text in an email to each recipient, just to each one. So I wonder if using some scripting this could be done in a non-interactive way in OS X. In Linux I think this could be done using "mutt".

• Log off as local "administrator" user, get blank login screen

  - by Force Flow

  I have an imaged lab environment running Windows 7 and attached to a domain. The local Administrator account is enabled for certain maintenance and prep tasks. Every time I logoff from the local Administrator account, it brings me back to the standard Ctrl+Alt+Del login screen. When I press that combination, all the user controls vanish except for the accessibility button down in the left hand corner. The only way I can seem to escape from this is to tap the power button to initiate a shutdown. Windows is up-to-date, and logging off as any other user operates normally. The "hide last user" local security policy option is enabled. Has anyone seen this phenomenon before and how can I stop this from happening?

• Wireless connection silently dies randomly

  - by Force Flow

  I have two WAP4410N wireless access points powered using Power-Over-Ethernet. They are both connected to the same LAN and broadcasting the same SSID with a WPA2 password. One is using channel 1, while the other is using channel 11. There is coverage overlap where the signal from both access points hover around -75db to -85db while standing in the same physical location. DHCP is disabled, and is being provided by another network device. Every day or so, devices can connect and authenticate to the access points, but are not granted an IP address (and subsequently are unable access to the LAN or Internet). For devices that had already retrieved an IP address prior to the issue exhibiting itself, the devices simply stop communicating with LAN and Internet. However, I can still access each access point's web admin interface from the LAN. If I reboot both devices, the problem vanishes and devices are once again able to get an IP address and connect to the LAN and Internet. Are these symptoms of signal interference between the two WAPs or is this a completely different issue?

• Row Number Transformation

  The Row Number Transformation calculates a row number for each row, and adds this as a new output column to the data flow. The column number is a sequential number, based on a seed value. Each row receives the next number in the sequence, based on the defined increment value. The final row number can be stored in a variable for later analysis, and can be used as part of a process to validate the integrity of the data movement. The Row Number transform has a variety of uses, such as generating surrogate keys, or as the basis for a data partitioning scheme when combined with the Conditional Split transformation. Properties Property Data Type Description Seed Int32 The first row number or seed value. Increment Int32 The value added to the previous row number to make the next row number. OutputVariable String The name of the variable into which the final row number is written post execution. (Optional). The three properties have been configured to support expressions, or they can set directly in the normal manner. Expressions on components are only visible on the hosting Data Flow task, not at the individual component level. Sometimes the data type of the property is incorrectly set when the properties are created, see the Troubleshooting section below for details on how to fix this. Installation The component is provided as an MSI file which you can download and run to install it. This simply places the files on disk in the correct locations and also installs the assemblies in the Global Assembly Cache as per Microsoft’s recommendations. You may need to restart the SQL Server Integration Services service, as this caches information about what components are installed, as well as restarting any open instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages. For 2005/2008 Only - Finally you will have to add the transformation to the Visual Studio toolbox manually. Right-click the toolbox, and select Choose Items.... Select the SSIS Data Flow Items tab, and then check the Row Number transformation in the Choose Toolbox Items window. This process has been described in detail in the related FAQ entry for How do I install a task or transform component? We recommend you follow best practice and apply the current Microsoft SQL Server Service pack to your SQL Server servers and workstations, and this component requires a minimum of SQL Server 2005 Service Pack 1. Downloads The Row Number Transformation  is available for SQL Server 2005, SQL Server 2008 (includes R2) and SQL Server 2012. Please choose the version to match your SQL Server version, or you can install multiple versions and use them side by side if you have more than one version of SQL Server installed. Row Number Transformation for SQL Server 2005 Row Number Transformation for SQL Server 2008 Row Number Transformation for SQL Server 2012 Version History SQL Server 2012 Version 3.0.0.6 - SQL Server 2012 release. Includes upgrade support for both 2005 and 2008 packages to 2012. (5 Jun 2012) SQL Server 2008 Version 2.0.0.5 - SQL Server 2008 release.

(18 Jun 2006) Version 1.0.0.0 - Public Release for SQL Server 2005 IDW 15 June CTP (29 Aug 2005) Screenshot Code Sample The following code sample demonstrates using the Data Generator Source and Row Number Transformation programmatically in a very simple package. Package package = new Package(); package.Name = "Data Generator & Row Number"; // Add the Data Flow Task Executable taskExecutable = package.Executables.Add("STOCK:PipelineTask"); // Get the task host wrapper, and the Data Flow task TaskHost taskHost = taskExecutable as TaskHost; MainPipe dataFlowTask = (MainPipe)taskHost.InnerObject; // Add Data Generator Source IDTSComponentMetaData100 componentSource = dataFlowTask.ComponentMetaDataCollection.New(); componentSource.Name = "Data Generator"; componentSource.ComponentClassID = "Konesans.Dts.Pipeline.DataGenerator.DataGenerator, Konesans.Dts.Pipeline.DataGenerator, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b2ab4a111192992b"; CManagedComponentWrapper instanceSource = componentSource.Instantiate(); instanceSource.ProvideComponentProperties(); instanceSource.SetComponentProperty("RowCount", 10000); // Add Row Number Tx IDTSComponentMetaData100 componentRowNumber = dataFlowTask.ComponentMetaDataCollection.New(); componentRowNumber.Name = "FlatFileDestination"; componentRowNumber.ComponentClassID = "Konesans.Dts.Pipeline.RowNumberTransform.RowNumberTransform, Konesans.Dts.Pipeline.RowNumberTransform, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b2ab4a111192992b"; CManagedComponentWrapper instanceRowNumber = componentRowNumber.Instantiate(); instanceRowNumber.ProvideComponentProperties(); instanceRowNumber.SetComponentProperty("Increment", 10); // Connect the two components together IDTSPath100 path = dataFlowTask.PathCollection.New(); path.AttachPathAndPropagateNotifications(componentSource.OutputCollection[0], componentRowNumber.InputCollection[0]); #if DEBUG // Save package to disk, DEBUG only new Application().SaveToXml(String.Format(@"C:\Temp\{0}.dtsx", package.Name), package, null); #endif package.Execute(); foreach (DtsError error in package.Errors) { Console.WriteLine("ErrorCode : {0}", error.ErrorCode); Console.WriteLine(" SubComponent : {0}", error.SubComponent); Console.WriteLine(" Description : {0}", error.Description); } package.Dispose(); Troubleshooting Make sure you have downloaded the version that matches your version of SQL Server. We offer separate downloads for SQL Server 2005, SQL Server 2008 and SQL Server 2012. If you get an error when you try and use the component along the lines of The component could not be added to the Data Flow task. Please verify that this component is properly installed.  ... The data flow object "Konesans ..." is not installed correctly on this computer, this usually indicates that the internal cache of SSIS components needs to be updated. This is held by the SSIS service, so you need restart the the SQL Server Integration Services service. You can do this from the Services applet in Control Panel or Administrative Tools in Windows. You can also restart the computer if you prefer. You may also need to restart any current instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages. Once installation is complete you need to manually add the task to the toolbox before you will see it and to be able add it to packages - How do I install a task or transform component? Please also make sure you have installed a minimum of SP1 for SQL 2005. The IDtsPipelineEnvironmentService was added in SQL Server 2005 Service Pack 1 (SP1) (See  http://support.microsoft.com/kb/916940). If you get an error Could not load type 'Microsoft.SqlServer.Dts.Design.IDtsPipelineEnvironmentService' from assembly 'Microsoft.SqlServer.Dts.Design, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91'. when trying to open the user interface, it implies that your development machine has not had SP1 applied. Very occasionally we get a problem to do with the properties not being created with the correct data type. Since there is no way to programmatically to define the data type of a pipeline component property, it can only infer it. Whilst we set an integer value as we create the property, sometimes SSIS decides to define it is a decimal. This is often highlighted when you use a property expression against the property and get an error similar to Cannot convert System.Int32 to System.Decimal. Unfortunately this is beyond our control and there appears to be no pattern as to when this happens. If you do have more information we would be happy to hear it. To fix this issue you can manually edit the package file. In Visual Studio right click the package file from the Solution Explorer and select View Code, which will open the package as raw XML. You can now search for the properties by name or the component name. You can then change the incorrect property data types highlighted below from Decimal to Int32. <component id="37" name="Row Number Transformation" componentClassID="{BF01D463-7089-41EE-8F05-0A6DC17CE633}" … >     <properties>         <property id="38" name="UserComponentTypeName" …>         <property id="41" name="Seed" dataType="System.Int32" ...>10</property>         <property id="42" name="Increment" dataType="System.Decimal" ...>10</property>         ... If you are still having issues then contact us, but please provide as much detail as possible about error, as well as which version of the the task you are using and details of the SSIS tools installed.

• SSIS code smell – Unused columns in the dataflow

  - by jamiet

  A code smell is defined on Wikipedia as being a “symptom in the source code of a program that possibly indicates a deeper problem”. It’s a term commonly used by our code-writing brethren to describe sub-optimal code but I think the term can be applied equally well to SSIS packages too as I shall now explain One of my pet hates about SSIS development is packages that throw warnings of the form: The output column "ColumnName" (1358) on output "OLE DB Source Output" (1289) and component "OLE_SRC Name" (1279) is not subsequently used in the Data Flow task. Removing this unused output column can increase Data Flow task performance.  The warning is fairly self-explanatory – any column that appears in the data flow but doesn’t get used will throw this warning when the data flow is executed. Its not the negligible performance degradation that they cause that bothers me though, it’s the clutter that they cause in your log file/table. Take a look at the following screenshot if you don’t believe me: There are 231409 such warnings in the system that I took this screenshot from, that is 231409 log records that should not be there. The most infuriating thing about this warning is that it is so easily avoidable; eliminating such columns is a very quick and easy thing to do in the SSIS Designer. The only problem I see is that the warnings don’t occur until you execute the package – it would be preferable for the designer to have an unobtrusive way of informing you of them as well. Anyway, I digress… I consider such warnings to be a code smell because, to me, they’re symptomatic of a lack of due care and attention; a lack of developer discipline if you will. What other code smells can you think of when building SSIS packages? If I get a good list in the comments maybe I’ll compile them into a later blog post. @Jamiet Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• AuthnRequest Settings in OIF / SP

  - by Damien Carru

  In this article, I will list the various OIF/SP settings that affect how an AuthnRequest message is created in OIF in a Federation SSO flow. The AuthnRequest message is used by an SP to start a Federation SSO operation and to indicate to the IdP how the operation should be executed: How the user should be challenged at the IdP Whether or not the user should be challenged at the IdP, even if a session already exists at the IdP for this user Which NameID format should be requested in the SAML Assertion Which binding (Artifact or HTTP-POST) should be requested from the IdP to send the Assertion Which profile should be used by OIF/SP to send the AuthnRequest message Enjoy the reading! Protocols The SAML 2.0, SAML 1.1 and OpenID 2.0 protocols define different message elements and rules that allow an administrator to influence the Federation SSO flows in different manners, when the SP triggers an SSO operation: SAML 2.0 allows extensive customization via the AuthnRequest message SAML 1.1 does not allow any customization, since the specifications do not define an authentication request message OpenID 2.0 allows for some customization, mainly via the OpenID 2.0 extensions such as PAPE or UI SAML 2.0 OIF/SP allows the customization of the SAML 2.0 AuthnRequest message for the following elements: ForceAuthn: Boolean indicating whether or not the IdP should force the user for re-authentication, even if the user has still a valid session By default set to false IsPassive Boolean indicating whether or not the IdP is allowed to interact with the user as part of the Federation SSO operation. If false, the Federation SSO operation might result in a failure with the NoPassive error code, because the IdP will not have been able to identify the user By default set to false RequestedAuthnContext Element indicating how the user should be challenged at the IdP If the SP requests a Federation Authentication Method unknown to the IdP or for which the IdP is not configured, then the Federation SSO flow will result in a failure with the NoAuthnContext error code By default missing NameIDPolicy Element indicating which NameID format the IdP should include in the SAML Assertion If the SP requests a NameID format unknown to the IdP or for which the IdP is not configured, then the Federation SSO flow will result in a failure with the InvalidNameIDPolicy error code If missing, the IdP will generally use the default NameID format configured for this SP partner at the IdP By default missing ProtocolBinding Element indicating which SAML binding should be used by the IdP to redirect the user to the SP with the SAML Assertion Set to Artifact or HTTP-POST By default set to HTTP-POST OIF/SP also allows the administrator to configure the server to: Set which binding should be used by OIF/SP to redirect the user to the IdP with the SAML 2.0 AuthnRequest message: Redirect or HTTP-POST By default set to Redirect Set which binding should be used by OIF/SP to redirect the user to the IdP during logout with SAML 2.0 Logout messages: Redirect or HTTP-POST By default set to Redirect SAML 1.1 The SAML 1.1 specifications do not define a message for the SP to send to the IdP when a Federation SSO operation is started. As such, there is no capability to configure OIF/SP on how to affect the start of the Federation SSO flow. OpenID 2.0 OpenID 2.0 defines several extensions that can be used by the SP/RP to affect how the Federation SSO operation will take place: OpenID request: mode: String indicating if the IdP/OP can visually interact with the user checkid_immediate does not allow the IdP/OP to interact with the user checkid_setup allows user interaction By default set to checkid_setup PAPE Extension: max_auth_age : Integer indicating in seconds the maximum amount of time since when the user authenticated at the IdP. If MaxAuthnAge is bigger that the time since when the user last authenticated at the IdP, then the user must be re-challenged. OIF/SP will set this attribute to 0 if the administrator configured ForceAuthn to true, otherwise this attribute won't be set Default missing preferred_auth_policies Contains a Federation Authentication Method Element indicating how the user should be challenged at the IdP By default missing Only specified in the OpenID request if the IdP/OP supports PAPE in XRDS, if OpenID discovery is used. UI Extension Popup mode Boolean indicating the popup mode is enabled for the Federation SSO By default missing Language Preference String containing the preferred language, set based on the browser's language preferences. By default missing Icon: Boolean indicating if the icon feature is enabled. In that case, the IdP/OP would look at the SP/RP XRDS to determine how to retrieve the icon By default missing Only specified in the OpenID request if the IdP/OP supports UI Extenstion in XRDS, if OpenID discovery is used. ForceAuthn and IsPassive WLST Command OIF/SP provides the WLST configureIdPAuthnRequest() command to set: ForceAuthn as a boolean: In a SAML 2.0 AuthnRequest, the ForceAuthn field will be set to true or false In an OpenID 2.0 request, if ForceAuthn in the configuration was set to true, then the max_auth_age field of the PAPE request will be set to 0, otherwise, max_auth_age won't be set IsPassive as a boolean: In a SAML 2.0 AuthnRequest, the IsPassive field will be set to true or false In an OpenID 2.0 request, if IsPassive in the configuration was set to true, then the mode field of the OpenID request will be set to checkid_immediate, otherwise set to checkid_setup Test In this test, OIF/SP is integrated with a remote SAML 2.0 IdP Partner, with the OOTB configuration. Based on this setup, when OIF/SP starts a Federation SSO flow, the following SAML 2.0 AuthnRequest would be generated: <samlp:AuthnRequest ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" ID="id-E4BOT7lwbYK56lO57dBaqGUFq01WJSjAHiSR60Q4" Version="2.0" IssueInstant="2014-04-01T21:39:14Z" Destination="https://acme.com/saml20/sso">   <saml:Issuer Format="urn:oasis:names:tc:SAML:2.0:nameid-format:entity">https://sp.com/oam/fed</saml:Issuer>   <samlp:NameIDPolicy AllowCreate="true"/></samlp:AuthnRequest> Let's configure OIF/SP for that IdP Partner, so that the SP will require the IdP to re-challenge the user, even if the user is already authenticated: Enter the WLST environment by executing:$IAM_ORACLE_HOME/common/bin/wlst.sh Connect to the WLS Admin server:connect() Navigate to the Domain Runtime branch:domainRuntime() Execute the configureIdPAuthnRequest() command:configureIdPAuthnRequest(partner="AcmeIdP", forceAuthn="true") Exit the WLST environment:exit() After the changes, the following SAML 2.0 AuthnRequest would be generated: <samlp:AuthnRequest ForceAuthn="true" ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" ID="id-E4BOT7lwbYK56lO57dBaqGUFq01WJSjAHiSR60Q4" Version="2.0" IssueInstant="2014-04-01T21:39:14Z" Destination="https://acme.com/saml20/sso">   <saml:Issuer Format="urn:oasis:names:tc:SAML:2.0:nameid-format:entity">https://sp.com/oam/fed</saml:Issuer>   <samlp:NameIDPolicy AllowCreate="true"/></samlp:AuthnRequest> To display or delete the ForceAuthn/IsPassive settings, perform the following operatons: Enter the WLST environment by executing:$IAM_ORACLE_HOME/common/bin/wlst.sh Connect to the WLS Admin server:connect() Navigate to the Domain Runtime branch:domainRuntime() Execute the configureIdPAuthnRequest() command: To display the ForceAuthn/IsPassive settings on the partnerconfigureIdPAuthnRequest(partner="AcmeIdP", displayOnly="true") To delete the ForceAuthn/IsPassive settings from the partnerconfigureIdPAuthnRequest(partner="AcmeIdP", delete="true") Exit the WLST environment:exit() Requested Fed Authn Method In my earlier "Fed Authentication Method Requests in OIF / SP" article, I discussed how OIF/SP could be configured to request a specific Federation Authentication Method from the IdP when starting a Federation SSO operation, by setting elements in the SSO request message. WLST Command The OIF WLST commands that can be used are: setIdPPartnerProfileRequestAuthnMethod() which will configure the requested Federation Authentication Method in a specific IdP Partner Profile, and accepts the following parameters: partnerProfile: name of the IdP Partner Profile authnMethod: the Federation Authentication Method to request displayOnly: an optional parameter indicating if the method should display the current requested Federation Authentication Method instead of setting it delete: an optional parameter indicating if the method should delete the current requested Federation Authentication Method instead of setting it setIdPPartnerRequestAuthnMethod() which will configure the specified IdP Partner entry with the requested Federation Authentication Method, and accepts the following parameters: partner: name of the IdP Partner authnMethod: the Federation Authentication Method to request displayOnly: an optional parameter indicating if the method should display the current requested Federation Authentication Method instead of setting it delete: an optional parameter indicating if the method should delete the current requested Federation Authentication Method instead of setting it This applies to SAML 2.0 and OpenID 2.0 protocols.

• How to set conditional activation to taskflows?

  - by shantala.sankeshwar(at)oracle.com

  This article describes implementing conditional activation to taskflows.Use Case Description Suppose we have a taskflow dropped as region on a page & this region is enclosed in a popup .By default when the page is loaded the respective region also gets loaded.Hence a region model needs to provide a viewId whenever one is requested.  A consequence of this is the TaskFlowRegionModel always has to initialize its task flow and execute the task flow's default activity in order to determine a viewId, even if the region is not visible on the page.This can lead to unnecessary performance overhead of executing task flow to generate viewIds for regions that are never visible. In order to increase the performance,we need to set the taskflow bindings activation property to 'conditional'.Below described is a simple usecase that shows how exactly we can set the conditional activations to taskflow bindings.Steps:1.Create an ADF Fusion web ApplicationView image 2.Create Business components for Emp tableView image3.Create a view criteria where deptno=:some_bind_variableView image4.Generate EmpViewImpl.java file & write the below code.Then expose this to client interface.    public void filterEmpRecords(Number deptNo){            // Code to filter the deptnos         ensureVariableManager().setVariableValue("some_bind_variable",  deptNo);        this.applyViewCriteria(this.getViewCriteria("EmpViewCriteria"));        this.executeQuery();       }5.Create an ADF Taskflow with page fragements & drop the above method on the taskflow6.Also drop the view activity(showEmp.jsff) .Define control flow case from the above method activity to the view activity.Set the method activity as default activityView image7.Create  main.jspx page & drop the above taskflow as region on this pageView image8.Surround the region with the dialog & surround the dialog with the popup(id is Popup1)9.Drop the commandButton on the above page & insert af:showPopupBehavior inside the commandButton:<af:commandButton text="show popup" id="cb1"><af:showPopupBehavior popupId="::Popup1"/></af:commandButton>10.Now if we execute this main page ,we will notice that the method action gets called even before the popup is launched.We can avoid this this by setting the activation property of the taskflow to conditional11.Goto the bindings of the above main page & select the taskflow binding ,set its activation property to 'conditional' & active property to Boolean value #{Somebean.popupVisible}.By default its value should be false.View image12.We need to set the above Boolean value to true only when the popup is launched.This can be achieved by inserting setPropertyListener inside the popup:<af:setPropertyListener from="true" to="#{Somebean.popupVisible}" type="popupFetch"/>13.Now if we run the page,we will notice that the method action is not called & only when we click on 'show popup' button the method action gets called.

• Why CoffeeScript is tough to maintain

  - by Renso

  I recently started trying out CoffeeScript only to find out that it caused more headaches. The abstraction level of jQuery was perfect, it did not dictate to coders how to design their code, it just works. However, I recently posted a request to the CoffeeScript team to consider introducing curly braces to help with more complex code to control the flow of logic. For example a if-then-else with many nested levels can be near impossible to debug without tracing through it when using CoffeeScript. Also with IDEs like Visual Studio, regular JavaScript intellicense and auto-formatting make it easy to appropriate indent nested levels without any work on the part of the developer and reading it is not that hard, especially with some extensions that show vertical lines in the code editor to help see what is nested within what part of the code.However with CoffeeScript that is not the case. The samples given in the CoffeeScript web site are of course just simple examples to explain the features and one gets excited pretty quick over the powerful shortcuts. I tried to convert a piece of JavaScript over to CoffeeScript and gave up since you need to first of all remove ALL non CoffeeScript coding constructs for it to even compile. However js2coffee can help with that. However to keep track of nested levels became something that was simply not manageable using CoffeeScript.Furthermore, any coding language that controls the flow of logic by indentation is extremely dangerous for obvious reasons. I liked CoffeeScript a lot, but the fact that the logical flow of the code is controlled by how much you indent code, spaces or tabs, is not reliable as there is no way the programmer has an easy way of knowing what parts of the code will get hit when the code spans a page.When I suggested introducing curly braces in CoffeeScript the team, one contributor advised me that my code needs to be re-designed! Needless to say that is absurd. When I included a piece of the code he asked my if it was legacy code. It's like saying to a Java programmer, sorry you cannot use Java because we don't agree with how you write your code.jashkenas from the CoffeeScript blog gave some great suggestions and made the point that introducing curly braces would be very problematic for them as they use them to denote objects. Makes sense, but I would still love to see some way to replace code flow control with spaces and indentation to something more concrete and human readable.

• How to model a many to many from a DDD perspective in UML?

  - by JD01

  I have a two entity objects Site and Customer where there is a many to many relationship. I have read you try not to model this in DDD as it is in the data model and go for a unidirectional flow. If I wanted to show this in UML, would I show it as it is in the data model: Site * ----->*Customer but the direction arrow gives the flow? or as following Site ----->*Customer But then this would imply that Customer can only go in one site.
