• Using a "white list" for extracting terms for Text Mining

  - by [email protected]

  In Part 1 of my post on "Generating cluster names from a document clustering model" (part 1, part 2, part 3), I showed how to build a clustering model from text documents using Oracle Data Miner, which automates preparing data for text mining. In this process we specified a custom stoplist and lexer and relied on Oracle Text to identify important terms.  However, there is an alternative approach, the white list, which uses a thesaurus object with the Oracle Text CTXRULE index to allow you to specify the important terms. INTRODUCTIONA stoplist is used to exclude, i.e., black list, specific words in your documents from being indexed. For example, words like a, if, and, or, and but normally add no value when text mining. Other words can also be excluded if they do not help to differentiate documents, e.g., the word Oracle is ubiquitous in the Oracle product literature. One problem with stoplists is determining which words to specify. This usually requires inspecting the terms that are extracted, manually identifying which ones you don't want, and then re-indexing the documents to determine if you missed any. Since a corpus of documents could contain thousands of words, this could be a tedious exercise. Moreover, since every word is considered as an individual token, a term excluded in one context may be needed to help identify a term in another context. For example, in our Oracle product literature example, the words "Oracle Data Mining" taken individually are not particular helpful. The term "Oracle" may be found in nearly all documents, as with the term "Data." The term "Mining" is more unique, but could also refer to the Mining industry. If we exclude "Oracle" and "Data" by specifying them in the stoplist, we lose valuable information. But it we include them, they may introduce too much noise. Still, when you have a broad vocabulary or don't have a list of specific terms of interest, you rely on the text engine to identify important terms, often by computing the term frequency - inverse document frequency metric. (This is effectively a weight associated with each term indicating its relative importance in a document within a collection of documents. We'll revisit this later.) The results using this technique is often quite valuable. As noted above, an alternative to the subtractive nature of the stoplist is to specify a white list, or a list of terms--perhaps multi-word--that we want to extract and use for data mining. The obvious downside to this approach is the need to specify the set of terms of interest. However, this may not be as daunting a task as it seems. For example, in a given domain (Oracle product literature), there is often a recognized glossary, or a list of keywords and phrases (Oracle product names, industry names, product categories, etc.). Being able to identify multi-word terms, e.g., "Oracle Data Mining" or "Customer Relationship Management" as a single token can greatly increase the quality of the data mining results. The remainder of this post and subsequent posts will focus on how to produce a dataset that contains white list terms, suitable for mining. CREATING A WHITE LIST We'll leverage the thesaurus capability of Oracle Text. Using a thesaurus, we create a set of rules that are in effect our mapping from single and multi-word terms to the tokens used to represent those terms. For example, "Oracle Data Mining" becomes "ORACLEDATAMINING." First, we'll create and populate a mapping table called my_term_token_map. All text has been converted to upper case and values in the TERM column are intended to be mapped to the token in the TOKEN column. TERM                                TOKEN DATA MINING                         DATAMINING ORACLE DATA MINING                  ORACLEDATAMINING 11G                                 ORACLE11G JAVA                                JAVA CRM                                 CRM CUSTOMER RELATIONSHIP MANAGEMENT    CRM ... Next, we'll create a thesaurus object my_thesaurus and a rules table my_thesaurus_rules: CTX_THES.CREATE_THESAURUS('my_thesaurus', FALSE); CREATE TABLE my_thesaurus_rules (main_term     VARCHAR2(100),                                  query_string  VARCHAR2(400)); We next populate the thesaurus object and rules table using the term token map. A cursor is defined over my_term_token_map. As we iterate over  the rows, we insert a synonym relationship 'SYN' into the thesaurus. We also insert into the table my_thesaurus_rules the main term, and the corresponding query string, which specifies synonyms for the token in the thesaurus. DECLARE   cursor c2 is     select token, term     from my_term_token_map; BEGIN   for r_c2 in c2 loop     CTX_THES.CREATE_RELATION('my_thesaurus',r_c2.token,'SYN',r_c2.term);     EXECUTE IMMEDIATE 'insert into my_thesaurus_rules values                        (:1,''SYN(' || r_c2.token || ', my_thesaurus)'')'     using r_c2.token;   end loop; END; We are effectively inserting the token to return and the corresponding query that will look up synonyms in our thesaurus into the my_thesaurus_rules table, for example:     'ORACLEDATAMINING'        SYN ('ORACLEDATAMINING', my_thesaurus)At this point, we create a CTXRULE index on the my_thesaurus_rules table: create index my_thesaurus_rules_idx on        my_thesaurus_rules(query_string)        indextype is ctxsys.ctxrule; In my next post, this index will be used to extract the tokens that match each of the rules specified. We'll then compute the tf-idf weights for each of the terms and create a nested table suitable for mining.

• Silverlight Tree View with Multiple Levels

  - by psheriff

  There are many examples of the Silverlight Tree View that you will find on the web, however, most of them only show you how to go to two levels. What if you have more than two levels? This is where understanding exactly how the Hierarchical Data Templates works is vital. In this blog post, I am going to break down how these templates work so you can really understand what is going on underneath the hood. To start, let’s look at the typical two-level Silverlight Tree View that has been hard coded with the values shown below: <sdk:TreeView>  <sdk:TreeViewItem Header="Managers">    <TextBlock Text="Michael" />    <TextBlock Text="Paul" />  </sdk:TreeViewItem>  <sdk:TreeViewItem Header="Supervisors">    <TextBlock Text="John" />    <TextBlock Text="Tim" />    <TextBlock Text="David" />  </sdk:TreeViewItem></sdk:TreeView> Figure 1 shows you how this tree view looks when you run the Silverlight application. Figure 1: A hard-coded, two level Tree View. Next, let’s create three classes to mimic the hard-coded Tree View shown above. First, you need an Employee class and an EmployeeType class. The Employee class simply has one property called Name. The constructor is created to accept a “name” argument that you can use to set the Name property when you create an Employee object. public class Employee{  public Employee(string name)  {    Name = name;  }   public string Name { get; set; }} Finally you create an EmployeeType class. This class has one property called EmpType and contains a generic List<> collection of Employee objects. The property that holds the collection is called Employees. public class EmployeeType{  public EmployeeType(string empType)  {    EmpType = empType;    Employees = new List<Employee>();  }   public string EmpType { get; set; }  public List<Employee> Employees { get; set; }} Finally we have a collection class called EmployeeTypes created using the generic List<> class. It is in the constructor for this class where you will build the collection of EmployeeTypes and fill it with Employee objects: public class EmployeeTypes : List<EmployeeType>{  public EmployeeTypes()  {    EmployeeType type;            type = new EmployeeType("Manager");    type.Employees.Add(new Employee("Michael"));    type.Employees.Add(new Employee("Paul"));    this.Add(type);     type = new EmployeeType("Project Managers");    type.Employees.Add(new Employee("Tim"));    type.Employees.Add(new Employee("John"));    type.Employees.Add(new Employee("David"));    this.Add(type);  }} You now have a data hierarchy in memory (Figure 2) which is what the Tree View control expects to receive as its data source. Figure 2: A hierachial data structure of Employee Types containing a collection of Employee objects. To connect up this hierarchy of data to your Tree View you create an instance of the EmployeeTypes class in XAML as shown in line 13 of Figure 3. The key assigned to this object is “empTypes”. This key is used as the source of data to the entire Tree View by setting the ItemsSource property as shown in Figure 3, Callout #1. Figure 3: You need to start from the bottom up when laying out your templates for a Tree View. The ItemsSource property of the Tree View control is used as the data source in the Hierarchical Data Template with the key of employeeTypeTemplate. In this case there is only one Hierarchical Data Template, so any data you wish to display within that template comes from the collection of Employee Types. The TextBlock control in line 20 uses the EmpType property of the EmployeeType class. You specify the name of the Hierarchical Data Template to use in the ItemTemplate property of the Tree View (Callout #2). For the second (and last) level of the Tree View control you use a normal <DataTemplate> with the name of employeeTemplate (line 14). The Hierarchical Data Template in lines 17-21 sets its ItemTemplate property to the key name of employeeTemplate (Line 19 connects to Line 14). The source of the data for the <DataTemplate> needs to be a property of the EmployeeTypes collection used in the Hierarchical Data Template. In this case that is the Employees property. In the Employees property there is a “Name” property of the Employee class that is used to display the employee name in the second level of the Tree View (Line 15). What is important here is that your lowest level in your Tree View is expressed in a <DataTemplate> and should be listed first in your Resources section. The next level up in your Tree View should be a <HierarchicalDataTemplate> which has its ItemTemplate property set to the key name of the <DataTemplate> and the ItemsSource property set to the data you wish to display in the <DataTemplate>. The Tree View control should have its ItemsSource property set to the data you wish to display in the <HierarchicalDataTemplate> and its ItemTemplate property set to the key name of the <HierarchicalDataTemplate> object. It is in this way that you get the Tree View to display all levels of your hierarchical data structure. Three Levels in a Tree View Now let’s expand upon this concept and use three levels in our Tree View (Figure 4). This Tree View shows that you now have EmployeeTypes at the top of the tree, followed by a small set of employees that themselves manage employees. This means that the EmployeeType class has a collection of Employee objects. Each Employee class has a collection of Employee objects as well. Figure 4: When using 3 levels in your TreeView you will have 2 Hierarchical Data Templates and 1 Data Template. The EmployeeType class has not changed at all from our previous example. However, the Employee class now has one additional property as shown below: public class Employee{  public Employee(string name)  {    Name = name;    ManagedEmployees = new List<Employee>();  }   public string Name { get; set; }  public List<Employee> ManagedEmployees { get; set; }} The next thing that changes in our code is the EmployeeTypes class. The constructor now needs additional code to create a list of managed employees. Below is the new code. public class EmployeeTypes : List<EmployeeType>{  public EmployeeTypes()  {    EmployeeType type;    Employee emp;    Employee managed;     type = new EmployeeType("Manager");    emp = new Employee("Michael");    managed = new Employee("John");    emp.ManagedEmployees.Add(managed);    managed = new Employee("Tim");    emp.ManagedEmployees.Add(managed);    type.Employees.Add(emp);     emp = new Employee("Paul");    managed = new Employee("Michael");    emp.ManagedEmployees.Add(managed);    managed = new Employee("Sara");    emp.ManagedEmployees.Add(managed);    type.Employees.Add(emp);    this.Add(type);     type = new EmployeeType("Project Managers");    type.Employees.Add(new Employee("Tim"));    type.Employees.Add(new Employee("John"));    type.Employees.Add(new Employee("David"));    this.Add(type);  }} Now that you have all of the data built in your classes, you are now ready to hook up this three-level structure to your Tree View. Figure 5 shows the complete XAML needed to hook up your three-level Tree View. You can see in the XAML that there are now two Hierarchical Data Templates and one Data Template. Again you list the Data Template first since that is the lowest level in your Tree View. The next Hierarchical Data Template listed is the next level up from the lowest level, and finally you have a Hierarchical Data Template for the first level in your tree. You need to work your way from the bottom up when creating your Tree View hierarchy. XAML is processed from the top down, so if you attempt to reference a XAML key name that is below where you are referencing it from, you will get a runtime error. Figure 5: For three levels in a Tree View you will need two Hierarchical Data Templates and one Data Template. Each Hierarchical Data Template uses the previous template as its ItemTemplate. The ItemsSource of each Hierarchical Data Template is used to feed the data to the previous template. This is probably the most confusing part about working with the Tree View control. You are expecting the content of the current Hierarchical Data Template to use the properties set in the ItemsSource property of that template. But you need to look to the template lower down in the XAML to see the source of the data as shown in Figure 6. Figure 6: The properties you use within the Content of a template come from the ItemsSource of the next template in the resources section. Summary Understanding how to put together your hierarchy in a Tree View is simple once you understand that you need to work from the bottom up. Start with the bottom node in your Tree View and determine what that will look like and where the data will come from. You then build the next Hierarchical Data Template to feed the data to the previous template you created. You keep doing this for each level in your Tree View until you get to the last level. The data for that last Hierarchical Data Template comes from the ItemsSource in the Tree View itself.

• What’s New for Oracle Commerce? Executive QA with John Andrews, VP Product Management, Oracle Commerce

  - by Katrina Gosek

  Oracle Commerce was for the fifth time positioned as a leader by Gartner in the Magic Quadrant for E-Commerce. This inspired me to sit down with Oracle Commerce VP of Product Management, John Andrews to get his perspective on what continues to make Oracle a leader in the industry and what’s new for Oracle Commerce in 2013. Q: Why do you believe Oracle Commerce continues to be a leader in the industry? John: Oracle has a great acquisition strategy – it brings best-of-breed technologies into the product fold and then continues to grow and innovate them. This is particularly true with products unified into the Oracle Commerce brand. Oracle acquired ATG in late 2010 – and then Endeca in late 2011. This means that under the hood of Oracle Commerce you have market-leading technologies for cross-channel commerce and customer experience, both designed and developed in direct response to the unique challenges online businesses face. And we continue to innovate on capabilities core to what our customers need to be successful – contextual and personalized experience delivery, merchant-inspired tools, and architecture for performance and scalability. Q: It’s not a slow moving industry. What are you doing to keep the pace of innovation at Oracle Commerce? John: Oracle owes our customers the most innovative commerce capabilities. By unifying the core components of ATG and Endeca we are delivering on this promise. Oracle Commerce is continuing to innovate and redefine how commerce is done and in a way that drive business results and keeps customers coming back for experiences tailored just for them. Our January and May 2013 releases not only marked the seventh significant releases for the solution since the acquisitions of ATG and Endeca, we also continue to demonstrate rapid and significant progress on the unification of commerce and customer experience capabilities of the two commerce technologies. Q: Can you tell us what was notable about these latest releases under the Oracle Commerce umbrella? John: Specifically, our latest product innovations give businesses selling online the ability to get to market faster with more personalized commerce experiences in the following ways: Mobile: the latest Commerce Reference Application in this release offers a wider range of examples for online businesses to leverage for iOS development and specifically new iPad reference capabilities. This release marks the first release of the iOS Universal application that serves both the iPhone and iPad devices from a single download or binary. Business users can now drive page content management and layout of search results and category pages, as well as create additional storefront elements such as categories, facets / dimensions, and breadcrumbs through Experience Manager tools. Cross-Channel Commerce: key commerce platform capabilities have been added to support cross-channel commerce, including an expanded inventory model to maintain inventory for stores, pickup in stores and Web-based returns. Online businesses with in-store operations can now offer advanced shipping options on the web and make returns and exchange logic easily available on the web. Multi-Site Capabilities: significant enhancements to the Commerce Platform multi-site architecture that allows business users to quickly launch and manage multiple sites on the same cluster and share data, carts, and other components. First introduced in 2010, with this latest release business users can now partition or share customer profiles, control users’ site-based access, and manage personalization assets using site groups. Internationalization: continued language support and enhancements for business user tools as well and search and navigation. Guided Search now supports 35 total languages with 11 new languages (including Danish, Arabic, Norwegian, Serbian Cyrillic) added in this release. Commerce Platform tools now include localized support for 17 locales with 4 new languages (Danish, Portuguese (European), Finnish, and Thai). No development or customization is required in order for business users to use the applications in any of these supported languages. Business Tool Experience: valuable new Commerce Merchandising features include a new workflow for making emergency changes quickly and increased visibility into promotions rules and qualifications in preview mode. Oracle Commerce business tools continue to become more and more feature rich to provide intuitive, easy- to-use (yet powerful) capabilities to allow business users to manage content and the shopping experience. Commerce & Experience Unification: demonstrable unification of commerce and customer experience capabilities include – productized cartridges that provide supported integration between the Commerce Platform and Experience Management tools, cross-channel returns, Oracle Service Cloud integration, and integrated iPad application. The mission guiding our product development is to deliver differentiated, personalized user experiences across any device in a contextual manner – and to give the business the best tools to tune and optimize those user experiences to meet their business objectives. We also need to do this in a way that makes it operationally efficient for the business, keeping the overall total cost of ownership low – yet also allows the business to expand, whether it be to new business models, geographies or brands.

• Routing Issue in ASP.NET MVC 3 RC 2

  - by imran_ku07

       Introduction:             Two weeks ago, ASP.NET MVC team shipped the ASP.NET MVC 3 RC 2 release. This release includes some new features and some performance optimization. This release also fixes most of the bugs but still some minor issues are present in this release. Some of these issues are already discussed by Scott Guthrie at Update on ASP.NET MVC 3 RC2 (and a workaround for a bug in it). In addition to these issues, I have found another issue in this release regarding routing. In this article, I will show you the issue regarding routing and a simple workaround for this issue.       Description:             The easiest way to understand an issue is to reproduce it in the application. So create a MVC 2 application and a MVC 3 RC 2 application. Then in both applications, just open global.asax file and update the default route as below,     routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id1}/{id2}", // URL with parameters new { controller = "Home", action = "Index", id1 = UrlParameter.Optional, id2 = UrlParameter.Optional } // Parameter defaults );              Then just open Index View and add the following lines,    <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Home Page </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <% Html.RenderAction("About"); %> </asp:Content>             The above view will issue a child request to About action method. Now run both applications. ASP.NET MVC 2 application will run just fine. But ASP.NET MVC 3 RC 2 application will throw an exception as shown below,                  You may think that this is a routing issue but this is not the case here as both ASP.NET MVC 2 and ASP.NET MVC  3 RC 2 applications(created above) are built with .NET Framework 4.0 and both will use the same routing defined in System.Web. Something is wrong in ASP.NET MVC 3 RC 2. So after digging into ASP.NET MVC source code, I have found that the UrlParameter class in ASP.NET MVC 3 RC 2 overrides the ToString method which simply return an empty string.     public sealed class UrlParameter { public static readonly UrlParameter Optional = new UrlParameter(); private UrlParameter() { } public override string ToString() { return string.Empty; } }             In MVC 2 the ToString method was not overridden. So to quickly fix the above problem just replace UrlParameter.Optional default value with a different value other than null or empty(for example, a single white space) or replace UrlParameter.Optional default value with a new class object containing the same code as UrlParameter class have except the ToString method is not overridden (or with a overridden ToString method that return a string value other than null or empty). But by doing this you will loose the benefit of ASP.NET MVC 2 Optional URL Parameters. There may be many different ways to fix the above problem and not loose the benefit of optional parameters. Here I will create a new class MyUrlParameter with the same code as UrlParameter class have except the ToString method is not overridden. Then I will create a base controller class which contains a constructor to remove all MyUrlParameter route data parameters, same like ASP.NET MVC doing with UrlParameter route data parameters early in the request.     public class BaseController : Controller { public BaseController() { if (System.Web.HttpContext.Current.CurrentHandler is MvcHandler) { RouteValueDictionary rvd = ((MvcHandler)System.Web.HttpContext.Current.CurrentHandler).RequestContext.RouteData.Values; string[] matchingKeys = (from entry in rvd where entry.Value == MyUrlParameter.Optional select entry.Key).ToArray(); foreach (string key in matchingKeys) { rvd.Remove(key); } } } } public class HomeController : BaseController { public ActionResult Index(string id1) { ViewBag.Message = "Welcome to ASP.NET MVC!"; return View(); } public ActionResult About() { return Content("Child Request Contents"); } }     public sealed class MyUrlParameter { public static readonly MyUrlParameter Optional = new MyUrlParameter(); private MyUrlParameter() { } }     routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id1}/{id2}", // URL with parameters new { controller = "Home", action = "Index", id1 = MyUrlParameter.Optional, id2 = MyUrlParameter.Optional } // Parameter defaults );             MyUrlParameter class is a copy of UrlParameter class except that MyUrlParameter class not overrides the ToString method. Note that the default route is modified to use MyUrlParameter.Optional instead of UrlParameter.Optional. Also note that BaseController class constructor is removing MyUrlParameter parameters from the current request route data so that the model binder will not bind these parameters with action method parameters. Now just run the ASP.NET MVC 3 RC 2 application again, you will find that it runs just fine.             In case if you are curious to know that why ASP.NET MVC 3 RC 2 application throws an exception if UrlParameter class contains a ToString method which returns an empty string, then you need to know something about a feature of routing for url generation. During url generation, routing will call the ParsedRoute.Bind method internally. This method includes a logic to match the route and build the url. During building the url, ParsedRoute.Bind method will call the ToString method of the route values(in our case this will call the UrlParameter.ToString method) and then append the returned value into url. This method includes a logic after appending the returned value into url that if two continuous returned values are empty then don't match the current route otherwise an incorrect url will be generated. Here is the snippet from ParsedRoute.Bind method which will prove this statement.       if ((builder2.Length > 0) && (builder2[builder2.Length - 1] == '/')) { return null; } builder2.Append("/"); ........................................................... ........................................................... ........................................................... ........................................................... if (RoutePartsEqual(obj3, obj4)) { builder2.Append(UrlEncode(Convert.ToString(obj3, CultureInfo.InvariantCulture))); continue; }             In the above example, both id1 and id2 parameters default values are set to UrlParameter object and UrlParameter class include a ToString method that returns an empty string. That's why this route will not matched.            Summary:             In this article I showed you the issue regarding routing and also showed you how to workaround this problem. I explained this issue with an example by creating a ASP.NET MVC 2 and a ASP.NET MVC 3 RC 2 application. Finally I also explained the reason for this issue. Hopefully you will enjoy this article too.   SyntaxHighlighter.all()

• jQuery Templates with ASP.NET MVC

  - by hajan

  In my three previous blogs, I’ve shown how to use Templates in your ASPX website. Introduction to jQuery TemplatesjQuery Templates - tmpl(), template() and tmplItem()jQuery Templates - {Supported Tags}Now, I will show one real-world example which you may use it in your daily work of developing applications with ASP.NET MVC and jQuery. In the following example I will use Pubs database so that I will retrieve values from the authors table. To access the data, I’m using Entity Framework. Let’s pass throughout each step of the scenario: 1. Create new ASP.NET MVC Web application 2. Add new View inside Home folder but do not select a master page, and add Controller for your View 3. BODY code in the HTML <body>     <div>         <h1>Pubs Authors</h1>         <div id="authorsList"></div>     </div> </body> As you can see  in the body we have only one H1 tag and a div with id authorsList where we will append the data from database.   4. Now, I’ve created Pubs model which is connected to the Pub database and I’ve selected only the authors table in my EDMX model. You can use your own database. 5. Next, lets create one method of JsonResult type which will get the data from database and serialize it into JSON string. public JsonResult GetAuthors() {     pubsEntities pubs = new pubsEntities();     var authors = pubs.authors.ToList();     return Json(authors, JsonRequestBehavior.AllowGet); } So, I’m creating object instance of pubsEntities and get all authors in authors list. Then returning the authors list by serializing it to JSON using Json method. The JsonRequestBehaviour.AllowGet parameter is used to make the GET requests from the client become allowed. By default in ASP.NET MVC 2 the GET is not allowed because of security issue with JSON hijacking.   6. Next, lets create jQuery AJAX function which will call the GetAuthors method. We will use $.getJSON jQuery method. <script language="javascript" type="text/javascript">     $(function () {         $.getJSON("GetAuthors", "", function (data) {             $("#authorsTemplate").tmpl(data).appendTo("#authorsList");         });     }); </script>   Once the web page is downloaded, the method will be called. The first parameter of $.getJSON() is url string in our case the method name. The second parameter (which in the example is empty string) is the key value pairs that will be send to the server, and the third function is the callback function or the result which is going to be returned from the server. Inside the callback function we have code that renders data with template which has id #authorsTemplate and appends it to element which has #authorsList ID.   7.

• Improving WIF&rsquo;s Claims-based Authorization - Part 2

  - by Your DisplayName here!

  In the last post I showed you how to take control over the invocation of ClaimsAuthorizationManager. Then you have complete freedom over the claim types, the amount of claims and the values. In addition I added two attributes that invoke the authorization manager using an “application claim type”. This way it is very easy to distinguish between authorization calls that originate from WIF’s per-request authorization and the ones from “within” you application. The attribute comes in two flavours: a CAS attribute (invoked by the CLR) and an ASP.NET MVC attribute (for MVC controllers, invoke by the MVC plumbing). Both also feature static methods to easily call them using the application claim types. The CAS attribute is part of Thinktecture.IdentityModel on Codeplex (or via NuGet: Install-Package Thinktecture.IdentityModel). If you really want to see that code ;) There is also a sample included in the Codeplex donwload. The MVC attribute is currently used in Thinktecture.IdentityServer – and I don’t currently plan to make it part of the library project since I don’t want to add a dependency on MVC for now. You can find the code below – and I will write about its usage in a follow-up post. public class ClaimsAuthorize : AuthorizeAttribute {     private string _resource;     private string _action;     private string[] _additionalResources;     /// <summary>     /// Default action claim type.     /// </summary>     public const string ActionType = "http://application/claims/authorization/action";     /// <summary>     /// Default resource claim type     /// </summary>     public const string ResourceType = "http://application/claims/authorization/resource";     /// <summary>     /// Additional resource claim type     /// </summary>     public const string AdditionalResourceType = "http://application/claims/authorization/additionalresource"          public ClaimsAuthorize(string action, string resource, params string[] additionalResources)     {         _action = action;         _resource = resource;         _additionalResources = additionalResources;     }     public static bool CheckAccess(       string action, string resource, params string[] additionalResources)     {         return CheckAccess(             Thread.CurrentPrincipal as IClaimsPrincipal,             action,             resource,             additionalResources);     }     public static bool CheckAccess(       IClaimsPrincipal principal, string action, string resource, params string[] additionalResources)     {         var context = CreateAuthorizationContext(             principal,             action,             resource,             additionalResources);         return ClaimsAuthorization.CheckAccess(context);     }     protected override bool AuthorizeCore(HttpContextBase httpContext)     {         return CheckAccess(_action, _resource, _additionalResources);     }     private static WIF.AuthorizationContext CreateAuthorizationContext(       IClaimsPrincipal principal, string action, string resource, params string[] additionalResources)     {         var actionClaims = new Collection<Claim>         {             new Claim(ActionType, action)         };         var resourceClaims = new Collection<Claim>         {             new Claim(ResourceType, resource)         };         if (additionalResources != null && additionalResources.Length > 0)         {             additionalResources.ToList().ForEach(ar => resourceClaims.Add(               new Claim(AdditionalResourceType, ar)));         }         return new WIF.AuthorizationContext(             principal,             resourceClaims,             actionClaims);     } }

• Programmatically reuse Dynamics CRM 4 icons

  - by gperera

  The team that wrote the dynamics crm sdk help rocks! I wanted to display the same crm icons on our time tracking application for consistency, so I opened up the sdk help file, searched for 'icon', ignored all the sitemap/isv config entries since I know I want to get these icons programatically, about half way down the search results I see 'organizationui', sure enough that contains the 16x16 (gridicon), 32x32 (outlookshortcuticon) and 66x48 (largeentityicon) icons!To get all the entities, execute a retrieve multiple request. RetrieveMultipleRequest request = new RetrieveMultipleRequest{    Query = new QueryExpression    {        EntityName = "organizationui",        ColumnSet = new ColumnSet(new[] { "objecttypecode", "formxml", "gridicon" }),    }}; var response = sdk.Execute(request) as RetrieveMultipleResponse;Now you have all the entities and icons, here's the tricky part, all the custom entities in crm store the icons inside gridicon, outlookshortcuticon and largeentityicon attributes, the built-in entity icons are stored inside the /_imgs/ folder with the format of /_imgs/ico_16_xxxx.gif (gridicon), with xxxx being the entity type code. The entity type code is not stored inside an attribute of organizationui, however you can get it by looking at the formxml attribute objecttypecode xml attribute. response.BusinessEntityCollection.BusinessEntities.ToList()    .Cast<organizationui>().ToList()    .ForEach(a =>    {        try        {            // easy way to check if it's a custom entity            if (!string.IsNullOrEmpty(a.gridicon))            {                byte[] gif = Convert.FromBase64String(a.gridicon);            }            else            {                // built-in entity                if (!string.IsNullOrEmpty(a.formxml))                {                    int start = a.formxml.IndexOf("objecttypecode=\"") + 16;                    int end = a.formxml.IndexOf("\"", start);                     // found the entity type code                    string code = a.formxml.Substring(start, end - start);                    string url = string.Format("/_imgs/ico_16_{0}.gif", code);Enjoy!

• Web Self Service installation on Windows

  - by Rajesh Sharma

  Web Self Service (WSS) installation on windows is pretty straight forward but you might face some issues if deployed under tomcat. Here's a step-by-step guide to install Oracle Utilities Web Self Service on windows.   Below installation steps are done on: Oracle Utilities Framework version 2.2.0 Oracle Utilities Application - Customer Care & Billing version 2.2.0 Application server - Apache Tomcat 6.0.13 on default port 6500 Other settings include: SPLBASE = C:\spl\CCBDEMO22 SPLENVIRON = CCBV22 SPLWAS = TCAT   Follow these steps for a Web Self Service installation on windows: Download Web Self Service application from edelivery.   Copy the delivery file Release-SelfService-V2.2.0.zip from the Oracle Utilities Customer Care and Billing version 2.2.0 Web Self Service folder on the installation media to a directory on your Windows box where you would like to install the application, in our case it's a temporary folder C:\wss_temp.   Setup application environment, execute splenviron.cmd -e <ENVIRON_NAME>   Create base folder for Self Service application named SelfService under %SPLEBASE%\splapp\applications   Install Oracle Utilities Web Self Service   C:\wss_temp\Release-SelfService-V2.2.0>install.cmd -d %SPLEBASE%\splapp\applications\SelfService   Web Self Service installation menu. Populate environment values for each item.   ******************************************************** Pick your installation options: ******************************************************** 1. Destination directory name for installation.             | C:\spl\CCBDEMO22\splapp\applications\SelfService 2. Web Server Host.                                         | CCBV22 3. Web Server Port Number.                                  | 6500 4. Mail SMTP Host.                                          | CCBV22 5. Top Product Installation directory.                      | C:\spl\CCBDEMO22 6.     Web Application Server Type.                         | TCAT 7.     When OAS: SPLWeb OC4J instance name is required.     | OC4J1 8.     When WAS: SPLWeb server instance name is required.   | server1   P. Process the installation. Each item in the above list should be configured for a successful installation. Choose option to configure or (P) to process the installation:  P   Option 7 and Option 8 can be ignored for TCAT.   Above step installs SelfService.war file in the destination directory. We need to explode this war file. Change directory to the installation destination folder, and   C:\spl\CCBDEMO22\splapp\applications\SelfService>jar -xf SelfService.war   Review SelfServiceConfig.properties and CMSelfServiceConfig.properties. Change any properties value within the file specific to your installation/site. Generally default settings apply, for this exercise assumes that WEB user already exists in your application database.   For more information on property file customization, refer to Oracle Utilities Web Self Service Configuration section in Customer Care & Billing Installation Guide.   Add context entry in server.xml located under tomcat-base folder C:\spl\CCBDEMO22\product\tomcatBase\conf   ... <!-- SPL Context -->           <Context path="" docBase="C:/spl/CCBDEMO22/splapp/applications/root" debug="0" privileged="true"/>           <Context path="/appViewer" docBase="C:/spl/CCBDEMO22/splapp/applications/appViewer" debug="0" privileged="true"/>           <Context path="/help" docBase="C:/spl/CCBDEMO22/splapp/applications/help" debug="0" privileged="true"/>           <Context path="/XAIApp" docBase="C:/spl/CCBDEMO22/splapp/applications/XAIApp" debug="0" privileged="true"/>           <Context path="/SelfService" docBase="C:/spl/CCBDEMO22/splapp/applications/SelfService" debug="0" privileged="true"/> ...   Add User in tomcat-users.xml file located under tomcat-base folder C:\spl\CCBDEMO22\product\tomcatBase\conf   <user username="WEB" password="selfservice" roles="cisusers"/>   Note the password is "selfservice", this is the default password set within the SelfServiceConfig.properties file with base64 encoding.   Restart the application (spl.cmd stop | start)   12.  Although Apache Tomcat version 6.0.13 does not come with the admin pack, you can verify whether SelfService application is loaded and running, go to following URL http://server:port/manager/list, in our case it'll be http://ccbv22:6500/manager/list Following output will be displayed   OK - Listed applications for virtual host localhost /admin:running:0:C:/tomcat/apache-tomcat-6.0.13/webapps/ROOT/admin /XAIApp:running:0:C:/spl/CCBDEMO22/splapp/applications/XAIApp /host-manager:running:0:C:/tomcat/apache-tomcat-6.0.13/webapps/host-manager /SelfService:running:0:C:/spl/CCBDEMO22/splapp/applications/SelfService /appViewer:running:0:C:/spl/CCBDEMO22/splapp/applications/appViewer /manager:running:1:C:/tomcat/apache-tomcat-6.0.13/webapps/manager /help:running:0:C:/spl/CCBDEMO22/splapp/applications/help /:running:0:C:/spl/CCBDEMO22/splapp/applications/root   Also ensure that the XAIApp is running.   Run Oracle Utilities Web Self Service application http://server:port/SelfService in our case it'll be  http://ccbv22:6500/SelfService   Still doesn't work? And you get '503 HTTP response' at the time of customer registration?     This is because XAI service is still unavailable. There is initialize.waittime set for a default value of 90 seconds for the XAI Application to come up.   Remember WSS uses XAI to perform actions/validations on the CC&B database.

• ASP.NET MVC for the php/asp noob

  - by dotjosh

  I was talking to a friend today, who's foremost a php developer, about his thoughts on Umbraco and he said "Well they're apparently working feverishly on the new version of Umbraco, which will be MVC... which i still don't know what that means, but I know you like it." I ended up giving him a ground up explanation of ASP.NET MVC, so I'm posting this so he can link this to his friends and for anyone else who finds it useful.  The whole goal was to be as simple as possible, not being focused on proper syntax. Model-View-Controller (or MVC) is just a pattern that is used for handling UI interaction with your backend.  In a typical web app, you can imagine the *M*odel as your database model, the *V*iew as your HTML page, and the *C*ontroller as the class inbetween.  MVC handles your web request different than your typical php/asp app.In your php/asp app, your url maps directly to a php/asp file that contains html, mixed with database access code and redirects.In an MVC app, your url route is mapped to a method on a class (the controller).  The body of this method can do some database access and THEN decide which *V*iew (html/aspx page) should be displayed;  putting the controller in charge and not the view... a clear seperation of concerns that provides better reusibility and generally promotes cleaner code. Mysite.com, a quick example:Let's say you hit the following url in your application: http://www.mysite.com/Product/ShowItem?Id=4 To avoid tedious configuration, MVC uses a lot of conventions by default. For instance, the above url in your app would automatically make MVC search for a .net class with the name "Product" and a method named "ShowItem" based on the pattern of the url.  So if you name things properly, your method would automatically be called when you entered the above url.  Additionally, it would automatically map/hydrate the "int id" parameter that was in your querystring, matched by name.Product.cspublic class Product : Controller{    public ViewResult ShowItem(int id)    {        return View();    }} From this point you can write the code in the body of this method to do some database access and then pass a "bag" (also known as the ViewData) of data to your chosen *V*iew (html page) to use for display.  The view(html) ONLY needs to be worried about displaying the flattened data that it's been given in the best way it can;  this allows the view to be reused throughout your application as *just* a view, and not be coupled to HOW the data for that view get's loaded.. Product.cspublic class Product : Controller{    public ViewResult ShowItem(int id)    {        var database = new Database();        var item = database.GetItem(id);        ViewData["TheItem"] = item;        return View();    }} Again by convention, since the class' method name is "ShowItem", it'll search for a view named "ShowItem.aspx" by default, and pass the ViewData bag to it to use. ShowItem.aspx<html>     <body>      <%        var item =(Item)ViewData["TheItem"]       %>       <h1><%= item.FullProductName %></h1>     </body></html> BUT WAIT! WHY DOES MICROSOFT HAVE TO DO THINGS SO DIFFERENTLY!?They aren't... here are some other frameworks you may have heard of that use the same pattern in a their own way: Ruby On Rails Grails Spring MVC Struts Django

• JPA - insert and retrieve clob and blob types

  - by pachunoori.vinay.kumar(at)oracle.com

  This article describes about the JPA feature for handling clob and blob data types.You will learn the following in this article. @Lob annotation Client code to insert and retrieve the clob/blob types End to End ADFaces application to retrieve the image from database table and display it in web page. Use Case Description Persisting and reading the image from database using JPA clob/blob type. @Lob annotation By default, TopLink JPA assumes that all persistent data can be represented as typical database data types. Use the @Lob annotation with a basic mapping to specify that a persistent property or field should be persisted as a large object to a database-supported large object type. A Lob may be either a binary or character type. TopLink JPA infers the Lob type from the type of the persistent field or property. For string and character-based types, the default is Clob. In all other cases, the default is Blob. Example Below code shows how to use this annotation to specify that persistent field picture should be persisted as a Blob. public class Person implements Serializable {    @Id    @Column(nullable = false, length = 20)    private String name;    @Column(nullable = false)    @Lob    private byte[] picture;    @Column(nullable = false, length = 20) } Client code to insert and retrieve the clob/blob types Reading a image file and inserting to Database table Below client code will read the image from a file and persist to Person table in database.                       Person p=new Person();                      p.setName("Tom");                      p.setSex("male");                      p.setPicture(writtingImage("Image location"));// - c:\images\test.jpg                       sessionEJB.persistPerson(p); //Retrieving the image from Database table and writing to a file                       List<Person> plist=sessionEJB.getPersonFindAll();//                      Person person=(Person)plist.get(0);//get a person object                      retrieveImage(person.getPicture());   //get picture retrieved from Table //Private method to create byte[] from image file  private static byte[] writtingImage(String fileLocation) {      System.out.println("file lication is"+fileLocation);     IOManager manager=new IOManager();        try {           return manager.getBytesFromFile(fileLocation);                    } catch (IOException e) {        }        return null;    } //Private method to read byte[] from database and write to a image file    private static void retrieveImage(byte[] b) {    IOManager manager=new IOManager();        try {            manager.putBytesInFile("c:\\webtest.jpg",b);        } catch (IOException e) {        }    } End to End ADFaces application to retrieve the image from database table and display it in web page. Please find the application in this link. Following are the j2ee components used in the sample application. ADFFaces(jspx page) HttpServlet Class - Will make a call to EJB and retrieve the person object from person table.Read the byte[] and write to response using Outputstream. SessionEJBBean - This is a session facade to make a local call to JPA entities JPA Entity(Person.java) - Person java class with setter and getter method annotated with @Lob representing the clob/blob types for picture field.

• Editing Routes in ASP.NET MVC

  - by imran_ku07

  Introduction :        Phil Haack's had written two great articles about Editable Routes, Editable Routes or Editable Routes Using App_Code.These Article are great. But if you not need to unit test your Routes and don't care about restart Application Domian during editing your Routes then global.asax file is the fastest and easiest to achieve the same. In this Article I will use Global.asax file instead of Global.asax.cs file for defining Routes and you will also see how this whole process will works.   Description :          You just need to Cut (or Copy) the code inside Global.asax.cs and paste it in Global.asax inside runat server tag.          You can simply do this by cutting the code of Global.asax.cs,          and paste it inside Global.asax,               Easy and quick ,Now you can change Global.asax without compiling the application. How this works :        I think it is worth here to see what is happening here.        Actually, ASP.NET will use Global.asax file to create a class named global_asax within ASP namespace and place all the code in Global.asax inside the class global_asax class which is created at runtime,                namespace ASP               {                    public class global_asax: NerdDinner.MvcApplication                    {                         //Any definitions defined in Global.asax like Application_Start method                                     }               }         Which inherits from class defined in Application tag,      <%@ Application Codebehind="Global.asax.cs" Inherits="NerdDinner.MvcApplication" Language="C#" %>          Actually ASP.NET creates a pool of application objects of this class, which varies from 1 to 100. Every request take one of these application objects to a serve incoming requests. After receiving an application object then it will call application specific events, like Application_Start(for only firstRequest), Application_BeginRequest(for every request), and so on. Therefore if these methods are defined in global_asax class then ASP.NET will call these method from global_asax, if not then it will use base class methods may be defined in Global.asax.cs(the concept known as shadowing or hiding). Summary :        In this article, I showed how easily and quickly you can make your Routes Editable. But also note that any change in global.asax results in Application Domain restart and this technique also makes your Route Unit Test difficult.

• ASP.NET, HTTP 404 and SEO

  - by paxer

  The other day our SEO Manager told me that he is not happy about the way ASP.NET application return HTTP response codes for Page Not Found (404) situation. I've started research and found interesting things, which could probably help others in similar situation.  1) By default ASP.NET application handle 404 error by using next web.config settings           <customErrors defaultRedirect="GenericError.htm" mode="On">             <error statusCode="404" redirect="404.html"/>           </customErrors> However this approach has a problem, and this is actually what our SEO manager was talking about. This is what HTTP return to request in case of Page not Found situation. So first of all it return HTTP 302 Redirect code and then HTTP 200 - ok code. The problem : We need to have HTTP 404 response code at the end of response for SEO purposes.  Solution 1 Let's change a bit our web.config settings to handle 404 error not on static html page but on .aspx page      <customErrors defaultRedirect="GenericError.htm" mode="On">             <error statusCode="404" redirect="404.aspx"/>           </customErrors> And now let's add in Page_Load event on 404.aspx page next lines     protected void Page_Load(object sender, EventArgs e)             {                 Response.StatusCode = 404;             } Now let's run our test again Now it has got better, last HTTP response code is 404, but my SEO manager still was not happy, becouse we still have 302 code before it, and as he said this is bad for Google search optimization. So we need to have only 404 HTTP code alone. Solution 2 Let's comment our web.config settings     <!--<customErrors defaultRedirect="GenericError.htm" mode="On">             <error statusCode="404" redirect="404.html"/>           </customErrors>--> Now, let's open our Global.asax file, or if it does not exist in your project - add it. Then we need to add next logic which will detect if server error code is 404 (Page not found) then handle it.       protected void Application_Error(object sender, EventArgs e)             {                            Exception ex = Server.GetLastError();                 if (ex is HttpException)                 {                     if (((HttpException)(ex)).GetHttpCode() == 404)                         Server.Transfer("~/404.html");                 }                 // Code that runs when an unhandled error occurs                 Server.Transfer("~/GenericError.htm");                  } Cool, now let's start our test again... Yehaa, looks like now we have only 404 HTTP response code, SEO manager and Google are happy and so do i:) Hope this helps!

• Customize Team Build 2010 – Part 13: Get control over the Build Output

  In the series the following parts have been published Part 1: Introduction Part 2: Add arguments and variables Part 3: Use more complex arguments Part 4: Create your own activity Part 5: Increase AssemblyVersion Part 6: Use custom type for an argument Part 7: How is the custom assembly found Part 8: Send information to the build log Part 9: Impersonate activities (run under other credentials) Part 10: Include Version Number in the Build Number Part 11: Speed up opening my build process template Part 12: How to debug my custom activities Part 13: Get control over the Build Output Part 14: Execute a PowerShell script Part 15: Fail a build based on the exit code of a console application     In the part 8, I have explained how you can add informational messages, warnings or errors to the build output. If you want to integrate with other lines of text to the build output, you need to do more. This post will show you how you can add extra steps, additional information and hyperlinks to the build output. Add an hyperlink to the end of the build output Lets start with a simple example of how you can adjust the build output. In this case we are going to add at the end of the build output an hyperlink where a user can click on to for example start the deployment to the test environment. In part 4 you can find information how you can create a custom activity To add information to the build output, you need the BuildDetail. This value is a variable in your xaml and is thus easily transferable to you custom activity. Besides the BuildDetail the user has also to specify the text and the url that has to be added to the end of the build output. The following code segment shows you how you can achieve this.     [BuildActivity(HostEnvironmentOption.All)]    public sealed class AddHyperlinkToBuildOutput : CodeActivity    {        [RequiredArgument]        public InArgument<IBuildDetail> BuildDetail { get; set; }         [RequiredArgument]        public InArgument<string> DisplayText { get; set; }         [RequiredArgument]        public InArgument<string> Url { get; set; }         protected override void Execute(CodeActivityContext context)        {            // Obtain the runtime value of the input arguments                        IBuildDetail buildDetail = context.GetValue(this.BuildDetail);            string displayText = context.GetValue(this.DisplayText);            string url = context.GetValue(this.Url);             // Add the hyperlink            buildDetail.Information.AddExternalLink(displayText, new Uri(url));            buildDetail.Information.Save();        }    } If you add this activity to somewhere in your build process template (within the scope Run on Agent), you will get the following build output Add an line of text to the build output The next challenge is to add this kind of output not only to the end of the build output but at the step that is currently executing. To be able to do this, you need the current node in the build output. The following code shows you how you can achieve this. First you need to get the current activity tracking, which you can get with the following line of code             IActivityTracking currentTracking = context.GetExtension<IBuildLoggingExtension>().GetActivityTracking(context); Then you can create a new node and set its type to Activity Tracking Node (so copy it from the current node) and do nice things with the node.             IBuildInformationNode childNode = currentTracking.Node.Children.CreateNode();            childNode.Type = currentTracking.Node.Type;            childNode.Fields.Add("DisplayText", "This text is displayed."); You can also add a build step to display progress             IBuildStep buildStep = childNode.Children.AddBuildStep("Custom Build Step", "This is my custom build step");            buildStep.FinishTime = DateTime.Now.AddSeconds(10);            buildStep.Status = BuildStepStatus.Succeeded; Or you can add an hyperlink to the node             childNode.Children.AddExternalLink("My link", new Uri(http://www.ewaldhofman.nl)); When you combine this together you get the following result in the build output     You can download the full solution at BuildProcess.zip. It will include the sources of every part and will continue to evolve.

• Fed Authentication Methods in OIF / IdP

  - by Damien Carru

  This article is a continuation of my previous entry where I explained how OIF/IdP leverages OAM to authenticate users at runtime: OIF/IdP internally forwards the user to OAM and indicates which Authentication Scheme should be used to challenge the user if needed OAM determine if the user should be challenged (user already authenticated, session timed out or not, session authentication level equal or higher than the level of the authentication scheme specified by OIF/IdP…) After identifying the user, OAM internally forwards the user back to OIF/IdP OIF/IdP can resume its operation In this article, I will discuss how OIF/IdP can be configured to map Federation Authentication Methods to OAM Authentication Schemes: When processing an Authn Request, where the SP requests a specific Federation Authentication Method with which the user should be challenged When sending an Assertion, where OIF/IdP sets the Federation Authentication Method in the Assertion Enjoy the reading! Overview The various Federation protocols support mechanisms allowing the partners to exchange information on: How the user should be challenged, when the SP/RP makes a request How the user was challenged, when the IdP/OP issues an SSO response When a remote SP partner redirects the user to OIF/IdP for Federation SSO, the message might contain data requesting how the user should be challenged by the IdP: this is treated as the Requested Federation Authentication Method. OIF/IdP will need to map that Requested Federation Authentication Method to a local Authentication Scheme, and then invoke OAM for user authentication/challenge with the mapped Authentication Scheme. OAM would authenticate the user if necessary with the scheme specified by OIF/IdP. Similarly, when an IdP issues an SSO response, most of the time it will need to include an identifier representing how the user was challenged: this is treated as the Federation Authentication Method. When OIF/IdP issues an Assertion, it will evaluate the Authentication Scheme with which OAM identified the user: If the Authentication Scheme can be mapped to a Federation Authentication Method, then OIF/IdP will use the result of that mapping in the outgoing SSO response: AuthenticationStatement in the SAML Assertion OpenID Response, if PAPE is enabled If the Authentication Scheme cannot be mapped, then OIF/IdP will set the Federation Authentication Method as the Authentication Scheme name in the outgoing SSO response: AuthenticationStatement in the SAML Assertion OpenID Response, if PAPE is enabled Mappings In OIF/IdP, the mapping between Federation Authentication Methods and Authentication Schemes has the following rules: One Federation Authentication Method can be mapped to several Authentication Schemes In a Federation Authentication Method <-> Authentication Schemes mapping, a single Authentication Scheme is marked as the default scheme that will be used to authenticate a user, if the SP/RP partner requests the user to be authenticated via a specific Federation Authentication Method An Authentication Scheme can be mapped to a single Federation Authentication Method Let’s examine the following example and the various use cases, based on the SAML 2.0 protocol: Mappings defined as: urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport mapped to LDAPScheme, marked as the default scheme used for authentication BasicScheme urn:oasis:names:tc:SAML:2.0:ac:classes:X509 mapped to X509Scheme, marked as the default scheme used for authentication Use cases: SP sends an AuthnRequest specifying urn:oasis:names:tc:SAML:2.0:ac:classes:X509 as the RequestedAuthnContext: OIF/IdP will authenticate the use with X509Scheme since it is the default scheme mapped for that method. SP sends an AuthnRequest specifying urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport as the RequestedAuthnContext: OIF/IdP will authenticate the use with LDAPScheme since it is the default scheme mapped for that method, not the BasicScheme SP did not request any specific methods, and user was authenticated with BasisScheme: OIF/IdP will issue an Assertion with urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport as the FederationAuthenticationMethod SP did not request any specific methods, and user was authenticated with LDAPScheme: OIF/IdP will issue an Assertion with urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport as the FederationAuthenticationMethod SP did not request any specific methods, and user was authenticated with BasisSessionlessScheme: OIF/IdP will issue an Assertion with BasisSessionlessScheme as the FederationAuthenticationMethod, since that scheme could not be mapped to any Federation Authentication Method (in this case, the administrator would need to correct that and create a mapping) Configuration Mapping Federation Authentication Methods to OAM Authentication Schemes is protocol dependent, since the methods are defined in the various protocols (SAML 2.0, SAML 1.1, OpenID 2.0). As such, the WLST commands to set those mappings will involve: Either the SP Partner Profile and affect all Partners referencing that profile, which do not override the Federation Authentication Method to OAM Authentication Scheme mappings Or the SP Partner entry, which will only affect the SP Partner It is important to note that if an SP Partner is configured to define one or more Federation Authentication Method to OAM Authentication Scheme mappings, then all the mappings defined in the SP Partner Profile will be ignored. Authentication Schemes As discussed in the previous article, during Federation SSO, OIF/IdP will internally forward the user to OAM for authentication/verification and specify which Authentication Scheme to use. OAM will determine if a user needs to be challenged: If the user is not authenticated yet If the user is authenticated but the session timed out If the user is authenticated, but the authentication scheme level of the original authentication is lower than the level of the authentication scheme requested by OIF/IdP So even though an SP requests a specific Federation Authentication Method to be used to challenge the user, if that method is mapped to an Authentication Scheme and that at runtime OAM deems that the user does not need to be challenged with that scheme (because the user is already authenticated, session did not time out, and the session authn level is equal or higher than the one for the specified Authentication Scheme), the flow won’t result in a challenge operation. Protocols SAML 2.0 The SAML 2.0 specifications define the following Federation Authentication Methods for SAML 2.0 flows: urn:oasis:names:tc:SAML:2.0:ac:classes:unspecified urn:oasis:names:tc:SAML:2.0:ac:classes:InternetProtocol urn:oasis:names:tc:SAML:2.0:ac:classes:Telephony urn:oasis:names:tc:SAML:2.0:ac:classes:MobileOneFactorUnregistered

urn:oasis:names:tc:SAML:2.0:ac:classes:SmartcardPKI urn:oasis:names:tc:SAML:2.0:ac:classes:TimeSyncToken Out of the box, OIF/IdP has the following mappings for the SAML 2.0 protocol: Only urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport is defined This Federation Authentication Method is mapped to: LDAPScheme, marked as the default scheme used for authentication

• Silverlight Recruiting Application Part 6 - Adding an Interview Scheduling Module/View

  Between the last post and this one I went ahead and carried the ideas for the Jobs module and view into the Applicants module and view- they're both doing more or less the same thing, except with different objects being at their core.  Made for an easy cut-and-paste operation with a few items being switched from one to another.  Now that we have the ability to add postings and applicants, wouldn't it be nice if we could schedule an interview?  Of course it would! Scheduling Module I think you get the drift from previous posts that these project structures start looking somewhat similar.  The interview scheduling module is no different than the rest- it gets a SchedulingModule.cs file at the root that inherits from IModule, and there is a single SchedulerView.xsml and SchedulerViewModel.cs setup for our V+VM.  We have one unique concern as we enter into this- RadScheduler deals with AppointmentsSource, not ItemsSource, so there are some special considerations to take into account when planning this module. First, I need something which inherits from AppointmentBase.  This is the core of the RadScheduler appointment, and if you are planning to do any form of custom appointment, you'll want it to inherit from this.  Then you can add-on functionality as needed.  Here is my addition to the mix, the InterviewAppointment: 01.public class InterviewAppointment : AppointmentBase 02.{ 03.    private int _applicantID; 04.    public int ApplicantID 05.    { 06.        get { return this._applicantID; } 07.        set 08.        { 09.            if (_applicantID != value) 10.            { 11.                _applicantID = value; 12.                OnPropertyChanged("ApplicantID"); 13.            } 14.        } 15.    } 16.   17.    private int _postingID; 18.    public int PostingID 19.    { 20.        get { return _postingID; } 21.        set 22.        { 23.            if (_postingID != value) 24.            { 25.                _postingID = value; 26.                OnPropertyChanged("PostingID"); 27.            } 28.        } 29.    } 30.   31.    private string _body; 32.    public string Body 33.    { 34.        get { return _body; } 35.        set 36.        { 37.            if (_body != value) 38.            { 39.                _body = value; 40.                OnPropertyChanged("Body"); 41.            } 42.        } 43.    } 44.   45.    private int _interviewID; 46.    public int InterviewID 47.    { 48.        get { return _interviewID; } 49.        set 50.        { 51.            if (_interviewID != value) 52.            { 53.                _interviewID = value; 54.                OnPropertyChanged("InterviewID"); 55.            } 56.        } 57.    } 58.   59.    public override IAppointment Copy() 60.    { 61.        IAppointment appointment = new InterviewAppointment(); 62.        appointment.CopyFrom(this);             63.        return appointment; 64.    } 65.   66.    public override void CopyFrom(IAppointment other) 67.    {             68.        base.CopyFrom(other); 69.        var appointment = other as InterviewAppointment; 70.        if (appointment != null) 71.        { 72.            ApplicantID = appointment.ApplicantID; 73.            PostingID = appointment.PostingID; 74.            Body = appointment.Body; 75.            InterviewID = appointment.InterviewID; 76.        } 77.    } 78.} Nothing too exciting going on here, we just make sure that our custom fields are persisted (specifically set in CopyFrom at the bottom) and notifications are fired- otherwise this ends up exactly like the standard appointment as far as interactions, etc.  But if we've got custom appointment items... that also means we need to customize what our appointment dialog window will look like. Customizing the Edit Appointment Dialog This initially sounds a lot more intimidating than it really is.  The first step here depends on what you're dealing with for theming, but for ease of everything I went ahead and extracted my templates in Blend for RadScheduler so I could modify it as I pleased.  For the faint of heart, the RadScheduler template is a few thousand lines of goodness since there are some very complex things going on in that control.  I've gone ahead and trimmed down the template parts I don't need as much as possible, so what is left is all that is relevant to the Edit Appointment Dialog.  Here's the resulting Xaml, with line numbers, so I can explain further: 001.<UserControl.Resources> 002.    <!-- begin Necessary Windows 7 Theme Resources for

template. Where we start getting into the dialog in question is line 132, but line 407 is where things start getting interesting.  The ItemsSource is pointing at a list that exists in my ViewModel (or code-behind, if it is used as a DataContext), the SelectedValue is the item I am actually binding from the applicant (note the TwoWay binding), and SelectedValuePath and DisplayMemberPath ensure the proper applicant is being displayed from the collection.  You will also see similar starting on line 420 where I do the same for the Jobs we'll be displaying. Just to wrap-up the Xaml, here's the RadScheduler declaraction that ties this all together and will be the main focus of our view: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02.                  Grid.Row="1" 03.                  Grid.Column="1" 04.                  Width="800" 05.                  MinWidth="600" 06.                  Height="500" 07.                  MinHeight="300" 08.                  AppointmentsSource="{Binding Interviews}" 09.                  EditAppointmentStyle="{StaticResource EditAppointmentStyle}" 10.                  command:AppointmentAddedEventClass.Command="{Binding AddAppointmentCommand}" 11.                  command:ApptCreatedEventClass.Command="{Binding ApptCreatingCommand}" 12.                  command:ApptEditedEventClass.Command="{Binding ApptEditedCommand}" 13.                  command:ApptDeletedEventClass.Command="{Binding ApptDeletedCommand}"> 14.</telerikScheduler:RadScheduler> Now, we get to the ViewModel and what it takes to get that rigged up.  And for those of you who remember the jobs post, those command:s in the Xaml are pointing to attached behavior commands that reproduce the respective events.  This becomes very handy when we're setting up the code-behind version. ;) ViewModel I've been liking this approach so far, so I'm going to put the entire ViewModel here and then go into the lines of interest.  Of course, feel free to ask me questions about anything that isn't clear (by line number, ideally) so I can help out if I have missed anything important: 001.public class SchedulerViewModel : ViewModelBase 002.{ 003.    private readonly IEventAggregator eventAggregator;

4.    base.ExecuteCommand(); 5.} And the ViewModel is none the wiser, the appointments just work as far as it is concerned since as they are created they become InterviewAppointments.  End result?  I've customized my EditAppointmentDialog as follows: And adding, editing, and deleting appointments works like a charm.  I can even 'edit' by moving appointments around RadScheduler, so as they are dropped into a timeslot they perform their full edit routine and things get updated. And then, the Code-Behind Version Perhaps the thing I like the most about doing one then the other is I get to steal 90% or more of the code from the MVVM version.  For example, the only real changes to the Code-Behind Xaml file exist in the control declaration, in which I use events instead of attached-behavior-event-commands: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02.                  Grid.Row="1" 03.                  Grid.Column="1" 04.                  Width="800" 05.                  MinWidth="600" 06.                  Height="500" 07.                  MinHeight="300" 08.                  EditAppointmentStyle="{StaticResource EditAppointmentStyle}" 09.                  AppointmentAdded="xJobsScheduler_AppointmentAdded" 10.                  AppointmentCreating="xJobsScheduler_AppointmentCreating" 11.                  AppointmentEdited="xJobsScheduler_AppointmentEdited" 12.                  AppointmentDeleted="xJobsScheduler_AppointmentDeleted"> 13.</telerikScheduler:RadScheduler> Easy, right?  Otherwise, all the same styling in UserControl.Resources was re-used, right down to the DataContextProxy that lets us bind to a collection from our viewmodel (in this case, our code-behind) to use within the DataTemplate.  The code conversion gets even easier, as I could literally copy and paste almost everything from the ViewModel to my Code-Behind, just a matter of pasting the right section into the right event.  Here's the code-behind as proof: 001.public partial class SchedulingView : UserControl, INotifyPropertyChanged 002.{ 003.    public RecruitingContext context;

So what have we learned here today?  One, for the most part this MVVM thing is somewhat easy.  Yeah, you sometimes have to write a bunch of extra code, but with the help of a few useful snippits you can turn the process into a pretty streamlined little workflow.  Heck, this story gets even easier as you can see in this blog post by Michael Washington- specifically run a find on 'InvokeCommandAction' and you'll see the section regarding the command on TreeView in Blend 4.  Brilliant!  MVVM never looked so sweet! Otherwise, it is business as usual with RadScheduler for Silverlight whichever path you're choosing for your development.  Between now and the next post, I'll be cleaning up styles a bit (those RadComboBoxes are a little too close to my labels!) and adding some to the RowDetailsViews for Applicants and Jobs, so you can see all the info for an appointment in the dropdown tab view.  Otherwise, we're about ready to call a wrap on this oneDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Globally Handling Request Validation In ASP.NET MVC

  - by imran_ku07

     Introduction:           Cross Site Scripting(XSS) and Cross-Site Request Forgery (CSRF) attacks are one of dangerous attacks on web.  They are among the most famous security issues affecting web applications. OWASP regards XSS is the number one security issue on the Web. Both ASP.NET Web Forms and ASP.NET MVC paid very much attention to make applications build with ASP.NET as secure as possible. So by default they will throw an exception 'A potentially dangerous XXX value was detected from the client', when they see, < followed by an exclamation(like <!) or < followed by the letters a through z(like <s) or & followed by a pound sign(like &#123) as a part of querystring, posted form and cookie collection. This is good for lot of applications. But this is not always the case. Many applications need to allow users to enter html tags, for example applications which uses  Rich Text Editor. You can allow user to enter these tags by just setting validateRequest="false" in your Web.config application configuration file inside <pages> element if you are using Web Form. This will globally disable request validation. But in ASP.NET MVC request handling is different than ASP.NET Web Form. Therefore for disabling request validation globally in ASP.NET MVC you have to put ValidateInputAttribute in your every controller. This become pain full for you if you have hundred of controllers. Therefore in this article i will present a very simple way to handle request validation globally through web.config.   Description:           Before starting how to do this it is worth to see why validateRequest in Page directive and web.config not work in ASP.NET MVC. Actually request handling in ASP.NET Web Form and ASP.NET MVC is different. In Web Form mostly the HttpHandler is the page handler which checks the posted form, query string and cookie collection during the Page ProcessRequest method, while in MVC request validation occur when ActionInvoker calling the action. Just see the stack trace of both framework.   ASP.NET MVC Stack Trace:     System.Web.HttpRequest.ValidateString(String s, String valueName, String collectionName) +8723114   System.Web.HttpRequest.ValidateNameValueCollection(NameValueCollection nvc, String collectionName) +111   System.Web.HttpRequest.get_Form() +129   System.Web.HttpRequestWrapper.get_Form() +11   System.Web.Mvc.ValueProviderDictionary.PopulateDictionary() +145   System.Web.Mvc.ValueProviderDictionary..ctor(ControllerContext controllerContext) +74   System.Web.Mvc.ControllerBase.get_ValueProvider() +31   System.Web.Mvc.ControllerActionInvoker.GetParameterValue(ControllerContext controllerContext, ParameterDescriptor parameterDescriptor) +53   System.Web.Mvc.ControllerActionInvoker.GetParameterValues(ControllerContext controllerContext, ActionDescriptor actionDescriptor) +109   System.Web.Mvc.ControllerActionInvoker.InvokeAction(ControllerContext controllerContext, String actionName) +399   System.Web.Mvc.Controller.ExecuteCore() +126   System.Web.Mvc.ControllerBase.Execute(RequestContext requestContext) +27   ASP.NET Web Form Stack Trace:    System.Web.HttpRequest.ValidateString(String s, String valueName, String collectionName) +3213202   System.Web.HttpRequest.ValidateNameValueCollection(NameValueCollection nvc, String collectionName) +108   System.Web.HttpRequest.get_QueryString() +119   System.Web.UI.Page.GetCollectionBasedOnMethod(Boolean dontReturnNull) +2022776   System.Web.UI.Page.DeterminePostBackMode() +60   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +6953   System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +154   System.Web.UI.Page.ProcessRequest() +86                        Since the first responder of request in ASP.NET MVC is the controller action therefore it will check the posted values during calling the action. That's why web.config's requestValidate not work in ASP.NET MVC.            So let's see how to handle this globally in ASP.NET MVC. First of all you need to add an appSettings in web.config. <appSettings>    <add key="validateRequest" value="true"/>  </appSettings>              I am using the same key used in disable request validation in Web Form. Next just create a new ControllerFactory by derving the class from DefaultControllerFactory.     public class MyAppControllerFactory : DefaultControllerFactory    {        protected override IController GetControllerInstance(Type controllerType)        {            var controller = base.GetControllerInstance(controllerType);            string validateRequest=System.Configuration.ConfigurationManager.AppSettings["validateRequest"];            bool b;            if (validateRequest != null && bool.TryParse(validateRequest,out b))                ((ControllerBase)controller).ValidateRequest = bool.Parse(validateRequest);            return controller;        }    }                         Next just register your controller factory in global.asax.        protected void Application_Start()        {            //............................................................................................            ControllerBuilder.Current.SetControllerFactory(new MyAppControllerFactory());        }              This will prevent the above exception to occur in the context of ASP.NET MVC. But if you are using the Default WebFormViewEngine then you need also to set validateRequest="false" in your web.config file inside <pages> element            Now when you run your application you see the effect of validateRequest appsetting. One thing also note that the ValidateInputAttribute placed inside action or controller will always override this setting.    Summary:          Request validation is great security feature in ASP.NET but some times there is a need to disable this entirely. So in this article i just showed you how to disable this globally in ASP.NET MVC. I also explained the difference between request validation in Web Form and ASP.NET MVC. Hopefully you will enjoy this.

• Thinktecture.IdentityModel: WIF Support for WCF REST Services and OData

  - by Your DisplayName here!

  The latest drop of Thinktecture.IdentityModel includes plumbing and support for WIF, claims and tokens for WCF REST services and Data Services (aka OData). Cibrax has an alternative implementation that uses the WCF Rest Starter Kit. His recent post reminded me that I should finally “document” that part of our library. Features include: generic plumbing for all WebServiceHost derived WCF services support for SAML and SWT tokens support for ClaimsAuthenticationManager and ClaimsAuthorizationManager based solely on native WCF extensibility points (and WIF) This post walks you through the setup of an OData / WCF DataServices endpoint with token authentication and claims support. This sample is also included in the codeplex download along a similar sample for plain WCF REST services. Setting up the Data Service To prove the point I have created a simple WCF Data Service that renders the claims of the current client as an OData set. public class ClaimsData {     public IQueryable<ViewClaim> Claims     {         get { return GetClaims().AsQueryable(); }     }       private List<ViewClaim> GetClaims()     {         var claims = new List<ViewClaim>();         var identity = Thread.CurrentPrincipal.Identity as IClaimsIdentity;           int id = 0;         identity.Claims.ToList().ForEach(claim =>             {                 claims.Add(new ViewClaim                 {                    Id = ++id,                    ClaimType = claim.ClaimType,                    Value = claim.Value,                    Issuer = claim.Issuer                 });             });           return claims;     } } …and hooked that up with a read only data service: public class ClaimsDataService : DataService<ClaimsData> {     public static void InitializeService(IDataServiceConfiguration config)     {         config.SetEntitySetAccessRule("*", EntitySetRights.AllRead);     } } Enabling WIF Before you enable WIF, you should generate your client proxies. Afterwards the service will only accept requests with an access token – and svcutil does not support that. All the WIF magic is done in a special service authorization manager called the FederatedWebServiceAuthorizationManager. This code checks incoming calls to see if the Authorization HTTP header (or X-Authorization for environments where you are not allowed to set the authorization header) contains a token. This header must either start with SAML access_token= or WRAP access_token= (for SAML or SWT tokens respectively). For SAML validation, the plumbing uses the normal WIF configuration. For SWT you can either pass in a SimpleWebTokenRequirement or the SwtIssuer, SwtAudience and SwtSigningKey app settings are checked.If the token can be successfully validated, ClaimsAuthenticationManager and ClaimsAuthorizationManager are invoked and the IClaimsPrincipal gets established. The service authorization manager gets wired up by the FederatedWebServiceHostFactory: public class FederatedWebServiceHostFactory : WebServiceHostFactory {     protected override ServiceHost CreateServiceHost(       Type serviceType, Uri[] baseAddresses)     {         var host = base.CreateServiceHost(serviceType, baseAddresses);           host.Authorization.ServiceAuthorizationManager =           new FederatedWebServiceAuthorizationManager();         host.Authorization.PrincipalPermissionMode = PrincipalPermissionMode.Custom;           return host;     } } The last step is to set up the .svc file to use the service host factory (see the sample download). Calling the Service To call the service you need to somehow get a token. This is up to you. You can either use WSTrustChannelFactory (for the full CLR), WSTrustClient (Silverlight) or some other way to obtain a token. The sample also includes code to generate SWT tokens for testing – but the whole WRAP/SWT support will be subject of a separate post. I created some extensions methods for the most common web clients (WebClient, HttpWebRequest, DataServiceContext) that allow easy setting of the token, e.g.: public static void SetAccessToken(this DataServiceContext context,   string token, string type, string headerName) {     context.SendingRequest += (s, e) =>     {         e.RequestHeaders[headerName] = GetHeader(token, type);     }; } Making a query against the Data Service could look like this: static void CallService(string token, string type) {     var data = new ClaimsData(new Uri("https://server/odata.svc/"));     data.SetAccessToken(token, type);       data.Claims.ToList().ForEach(c =>         Console.WriteLine("{0}\n {1}\n ({2})\n", c.ClaimType, c.Value, c.Issuer)); } HTH

Today’s market has moved from network centric to consumer centric and focuses primarily on the customer experience. It has resulted in several product management challenges such as an increased complexity and volume of offerings, creating product variants, accelerating time-to-market, ability to provide multiple product views for varied stakeholders, leveraging OSS intelligence to BSS layer, product co-creation and increasing audit and security concerns for service providers. The document discusses how enterprise product management enabled by PLM-based product catalogue solutions helps to launch next generation products rapidly in the context of the Telecommunication Industry.   1.0.       Introduction   Figure 1: Business Scenario   Modern business demands the launch of complex products in a very short timeframe and effecting changes in the price plan faster without IT intervention. One of the key transformation initiatives companies are focusing on is in the area of product management transformation and operational efficiency improvement. As part of these initiatives, companies are investing in best- in-class COTs-based Product Management solutions developed on industry-wide standards.   The new COTs packages are planned to integrate with existing or new B/OSS systems to provide a strategic end-to-end agile solution for reduced time-to-market and order journey time. In addition, system rationalization is being undertaken to phase out legacy systems and migrate to strategic systems.   2.0.       An Overview of Product Management in Telecom   Product data in telecom is multi- dimensional and difficult to manage. It increased significantly due to the complexity of the product, product offerings on the converged network, increased volume of offerings, bundled offering structures and ever increasing regulatory requirements.   In addition, the shrinking product lifecycle in telecom makes it difficult to manage the dynamic product data. Mergers and acquisitions coupled with organic growth pose major challenges in product portfolio management. It is a roadblock in the journey towards becoming an agile organization.       Figure 2: Complexity in Product Management   Network Technology’ is the new dimension in telecom product management where the same products are realized through different networks i.e., Soiled network to Converged network. Consequently, the product solution is different.     Figure 3: Current Scenario - Pain Points in Product Management   The major business implications arising out of the current scenario are slow time-to-market and an inefficient process that affects innovation.   3.0. Transformation of Next Generation Product Management   Companies must focus on their Product Management Transformation Journey in the areas of:   ·       Management of single truth of product information across the organization/geographies which is currently managed in heterogeneous systems   ·       Management of the Intellectual Property (IP) on the product concept and partnership in the design of discrete components to integrate into the system   ·       Leveraging structured and unstructured product data within the extended enterprise to extract consumer insights and drive innovation   ·       Management of effective operational separation to comply with regulatory bodies   ·       Reuse of existing designs and add relevant features such as value-added services to enable effective product bundling     Figure 4: Next generation needs   PLM-based Enterprise Product Catalogue solutions efficiently address the above requirements and act as an enabler towards product management transformation and rapid product launch.   4.0. PLM-based Enterprise Product Management     Figure 5: PLM-based Enterprise Product Mastering   Enterprise Product Management (EPM) enables the business to manage complex product attributes of data in complex environments. Product Mastering helps create a 'single view' of the product by creating a business-driven, IT-supported environment where a global 'single truth record' is created, managed and reused.   4.1 The Business Case for Telco PLM-based solutions for Enterprise Product Management   ·       Telco PLM-based Product Mastering solutions provide a centralized authoring environment for product definition and control of all product data and rules   ·       PLM packages are designed to support multiple perspectives of product data (ordering perspective, billing perspective, provisioning perspective)   ·       Maintains relationships/links between different elements of the entire product definition   ·       Telco PLM packages are specialized in next generation lifecycle management requirements of products such as revision and state management, test and release management, role management and impact analysis)   ·       Takes into consideration all aspects of OSS product requirements compared to CRM product catalogue solutions where the product data managed is mostly order oriented and transactional     ·       New breed of Telco PLM packages are designed with 'open' standards such as SID and eTOM. They are interoperable, support integration frameworks such as subscription and notification.   ·       Telco PLM packages have developed good collaboration frameworks to integrate suppliers and partners into the product development value chain   4.2 Various Architectures/Approaches for Product Mastering using Telco PLM systems   4. 2.a Single Central Product Management (Mastering) Approach   Figure 6: Single Central Product Management (Master) Approach       This approach is implemented across verticals such as aerospace and automotive. It focuses on a physically centralized product master to which other sources are dependent on. The product definition data (Product bundles, service bundles, price plans, offers and discounts, product configuration rules and market campaigns) is created and maintained physically in a centralized environment. In addition, the product definition/authoring environment is centralized. The existing legacy product definition data available in CRM product catalogue, billing catalogue and the legacy product catalogue is migrated to the centralized PLM-based Enterprise Product Management solution.   Architectural changes must be made in the existing business landscape of applications to create and revise data because the applications have to refer to the central repository for approvals and validation of product configurations. It is achieved by modifying how the applications write data or how the applications can be adapted to use the rules to be managed and published.   Complete product configuration validation will be done in enterprise / central product catalogue and final configuration will be sent to the B/OSS system through the SOA compliant product distribution architecture. The approach/architecture enables greater control in terms of product data management and product data governance.   4.2.b Federated Product Management (Mastering) Architecture     Figure 7: Federated Product Management (Mastering) Architecture   In the federated product mastering approach, the basic unique product definition data (product id, description product hierarchy, basic price plans and simple product design rules) will be centrally created and will be maintained. And, the advanced product definition (Product bundling, promotions, offers & discount plans) will be created in respective down stream OSS systems. The advanced product definition (Product bundling, promotions, offers and discount plans) will be created in respective downstream OSS systems.   For example, basic product definitions such as attributes, product hierarchy and basic price plans will be created and maintained in Enterprise/Central product reference catalogue and distributed to downstream OSS systems. Respective downstream OSS systems build product bundles, promotions, advanced price plans over the basic product definition and master the advanced product definition. Central reference database accesses the respective other source product master data and assembles a point-in-time consolidated view of the product. The approach is typically adapted in some merger and acquisition scenarios where there is a low probability of a central physical authority managing the data. In addition, the migration effort in this case is minimal and there are no big architectural changes to the organization application landscape. However, this approach will not result in better product data management and data governance.   5.0 Customer Scenario – Before EPC deployment   A leading global telecommunications service provider wanted to launch a quad play and triple play service offering in the shortest possible lead time. The service provider was offering Broadband and VoIP services to customers. The company wanted to reuse a majority of the Broadband services and price plans and bundle them with new wireless and IPTV services for quad play and triple play. The challenges in launching the new service offerings were:       Figure 8: Triple Play Plan   ·       Broadband product data was stored in multiple product catalogues (CRM catalogue, Billing catalogue, spread sheets)   ·       Product managers spent a lot of time performing tasks involving duplication or re-keying of data. Manual effort caused errors, cost and time over-runs.   ·       No effective product and price data governance mechanism. Price change issues arising from the lack of data consistency across systems resulted in leakage of customer value and revenue.   ·       Product data had re-usability issues and was not in a structured format. It resulted in uncontrolled product portfolio creation and product management issues.   ·       Lack of enterprise product model resulted into product distribution challenges and thus delays in product launch.   ·       Designers are constrained by existing legacy product management solutions to model product/service requirements and product configuration rules such as upgrading, downgrading and cross selling.    5.1 Customer Scenario - After EPC deployment     Figure 9: SOA-based end-to-end EPC Solution   The company deployed PLM-based Enterprise Product Catalogue solutions to launch quad play service after evaluating various product catalogues. The broadband product offering, service and price data were migrated to the new system, and the product and price plan hierarchy for new offerings were created using the entities defined in the Enterprise Product Model. Supplier product catalogue data such as routers and set up boxes were loaded onto the new solution through SOA-based web service. Price plans and configuration rules were built in the new system. The validated final product configurations were extracted from the product catalogue in a SID format and were distributed to the downstream B/OSS systems through exposed SOA-based web services. The transformations required for the B/OSS system were handled using the transformation layer as part of the solution.   6.0 How PLM enabled Product Management Transformation         Figure 10: Product Management Transformation     PLM-based Product Catalogue Solution helped the customer reduce the product launch cycle time by 30% and enable transformation of Product Management for next generation services.   7.0 Conclusion   On the one hand, the telecom industry is undergoing changes due to disruptions, uncertain product markets and increased complexity of products. On the other hand, the ARPU is decreasing year-on-year. Communications Service Providers are embarking on convergence, bundled service offerings, flexibility to cross-sell and up-sell, introduce new value-added services, leverage Web 2.0 concepts and network capabilities. Consequently, large scale IT transformation initiatives to improve their ARPU supporting network and business transformations are a business imperative. Product Management has become a focus area. Companies are investing in best-in- class COTS solutions to reduce time-to-market, ensure rapid service delivery and improve operational efficiency. An efficient PLM-based enterprise product mastering solution plays a key role in achieving zero touch automation and rapid product launch.   References:   1.     Preston G.Smith, Donald G.Reineristsem, Van Nostrand Reinhold “Developing Products in Half the time”.   2.     John G.

• Upload Certificate and Key to RUEI in order to decrypt SSL traffic

  - by stefan.thieme(at)oracle.com

  So you want to monitor encrypted traffic with your RUEI collector ?Actually this is an easy thing if you follow the lines below...I will start out with creating a pair of snakeoil (so called self-signed) certificate and key with the make-ssl-cert tool which comes pre-packaged with apache only for the purpose of this example.$ sudo make-ssl-cert generate-default-snakeoil$ sudo ls -l /etc/ssl/certs/ssl-cert-snakeoil.pem /etc/ssl/private/ssl-cert-snakeoil.key-rw-r--r-- 1 root root     615 2010-06-07 10:03 /etc/ssl/certs/ssl-cert-snakeoil.pem-rw-r----- 1 root ssl-cert 891 2010-06-07 10:03 /etc/ssl/private/ssl-cert-snakeoil.keyRUEI Configuration of Security SSL Keys You will most likely get these two files from your Certificate Authority (CA) and/or your system administrators should be able to extract this from your WebServer or LoadBalancer handling SSL encryption for your infrastructure.Now let's look at the content of these two files, the certificate (apache assumes this is in PEM format) is called a public key and the private key is used by the apache server to encrypt traffic for a client using the certificate to initiate the SSL connection with the server.In case you already know that these two match, you simply have to paste them in one text file and upload this text file to your RUEI instance.$ sudo cat /etc/ssl/certs/ssl-cert-snakeoil.pem /etc/ssl/private/ssl-cert-snakeoil.key > /tmp/ruei.cert_and_key$ sudo cat /tmp/ruei.cert_and_key -----BEGIN CERTIFICATE----- MIIBmTCCAQICCQD7O3XXwVilWzANBgkqhkiG9w0BAQUFADARMQ8wDQYDVQQDEwZ1 YnVudHUwHhcNMTAwNjA3MDgwMzUzWhcNMjAwNjA0MDgwMzUzWjARMQ8wDQYDVQQD EwZ1YnVudHUwgZ8wDQYJKoZIhvcNAQEBBQADgY0AMIGJAoGBALbs+JnI+p+K7Iqa SQZdnYBxOpdRH0/9jt1QKvmH68v81h9+f1Z2rVR7Zrd/l+ruE3H9VvuzxMlKuMH7 qBX/gmjDZTlj9WJM+zc0tSk+e2udy9he20lGzTxv0vaykJkuKcvSWNk4WE9NuAdg IHZvjKgoTSVmvM1ApMCg69nyOy97AgMBAAEwDQYJKoZIhvcNAQEFBQADgYEAk2rv VEkxR1qPSpJiudDuGUHtWKBKWiWbmSwI3REZT+0vG+YDG5a55NdxgRk3zhQntqF7 gNYjKxblBByBpY7W0ci00kf7kFgvXWMeU96NSQJdnid/YxzQYn0dGL2rSh1dwdPN NPQlNSfnEQ1yxFevR7aRdCqTbTXU3mxi8YaSscE= -----END CERTIFICATE----- -----BEGIN RSA PRIVATE KEY----- MIICXgIBAAKBgQC27PiZyPqfiuyKmkkGXZ2AcTqXUR9P/Y7dUCr5h+vL/NYffn9W dq1Ue2a3f5fq7hNx/Vb7s8TJSrjB+6gV/4Jow2U5Y/ViTPs3NLUpPntrncvYXttJ Rs08b9L2spCZLinL0ljZOFhPTbgHYCB2b4yoKE0lZrzNQKTAoOvZ8jsvewIDAQAB AoGBAJ7LCWeeUwnKNFqBYmD3RTFpmX4furnal3lBDX0945BZtJr0WZ/6N679zIYA aiVTdGfgjvDC9lHy3n3uctRd0Jqdh2QoSSxNBhq5elIApNIIYzu7w/XI/VhGcDlA b6uadURQEC2q+M8YYjw3mwR2omhCWlHIViOHe/9T8jfP/8pxAkEA7k39WRcQildH DFKcj7gurqlkElHysacMTFWf0ZDTEUS6bdkmNXwK6mH63BlmGLrYAP5AMgKgeDf8 D+WRfv8YKQJBAMSCQ7UGDN3ysyfIIrdc1RBEAk4BOrKHKtD5Ux0z5lcQkaCYrK8J DuSldreN2yOhS99/S4CRWmGkTj04wRSnjwMCQQCaR5mW3QzTU4/m1XEQxsBKSdZE 2hMSmsCmhuSyK13Kl0FPLr/C7qyuc4KSjksABa8kbXaoKfUz/6LLs+ePXZ2JAkAv +mIPk5+WnQgS4XFgdYDrzL8HTpOHPSs+BHG/goltnnT/0ebvgXWqa5+1pyPm6h29 PrYveM2pY1Va6z1xDowDAkEAttfzAwAHz+FUhWQCmOBpvBuW/KhYWKZTMpvxFMSY YD5PH6NNyLfBx0J4nGPN5n/f6il0s9pzt3ko++/eUtWSnQ== -----END RSA PRIVATE KEY----- Simply click on the add new key and browse for the cert_and_key file on your desktop which you concatenated earlier using any text editor. You may need to add a passphrase in order to decrypt the RSA key in some cases (it should tell you BEGIN ENCRYPTED PRIVATE KEY in the header line). I will show you the success screen after uploading the certificate to RUEI. You may want to restart your collector once you have uploaded all the certificate/key pairs you want to use in order to make sure they get picked up asap.You should be able to see the number of SSL Connections rising in the Collector statistics screen below. The figures for decrypt errors should slowly go down and the usage figures for your encryption algortihm on the subsequent SSL Encryption screen should go up.

This tells Wireshark to leave out any other information, I may not have been interested in showing you.

• Grouping data in LINQ with the help of group keyword

  - by vik20000in

  While working with any kind of advanced query grouping is a very important factor. Grouping helps in executing special function like sum, max average etc to be performed on certain groups of data inside the date result set. Grouping is done with the help of the Group method. Below is an example of the basic group functionality.     int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 };         var numberGroups =         from num in numbers         group num by num % 5 into numGroup         select new { Remainder = numGroup.Key, Numbers = numGroup };  In the above example we have grouped the values based on the reminder left over when divided by 5. First we are grouping the values based on the reminder when divided by 5 into the numgroup variable.  numGroup.Key gives the value of the key on which the grouping has been applied. And the numGroup itself contains all the records that are contained in that group. Below is another example to explain the same. string[] words = { "blueberry", "abacus", "banana", "apple", "cheese" };         var wordGroups =         from num in words         group num by num[0] into grp         select new { FirstLetter = grp.Key, Words = grp }; In the above example we are grouping the value with the first character of the string (num[0]). Just like the order operator the group by clause also allows us to write our own logic for the Equal comparison (That means we can group Item by ignoring case also by writing out own implementation). For this we need to pass an object that implements the IEqualityComparer<string> interface. Below is an example. public class AnagramEqualityComparer : IEqualityComparer<string> {     public bool Equals(string x, string y) {         return getCanonicalString(x) == getCanonicalString(y);     }      public int GetHashCode(string obj) {         return getCanonicalString(obj).GetHashCode();     }         private string getCanonicalString(string word) {         char[] wordChars = word.ToCharArray();         Array.Sort<char>(wordChars);         return new string(wordChars);     } }  string[] anagrams = {"from   ", " salt", " earn", "  last   ", " near "}; var orderGroups = anagrams.GroupBy(w => w.Trim(), new AnagramEqualityComparer()); Vikram

• Using Rich Text Editor (WYSIWYG) in ASP.NET MVC

  - by imran_ku07

     Introduction:          In ASP.NET MVC forum I found some question regarding a sample HTML Rich Text Box Editor(also known as wysiwyg).So i decided to create a sample ASP.NET MVC web application which will use a Rich Text Box Editor. There are are lot of Html Editors are available, but for creating a sample application, i decided to use cross-browser WYSIWYG editor from openwebware. In this article I will discuss what changes needed to work this editor with ASP.NET MVC. Also I had attached the sample application for download at http://www.speedfile.org/155076. Also note that I will only show the important features, not discuss every feature in detail.   Description:          So Let's start create a sample ASP.NET MVC application. You need to add the following script files,         jquery-1.3.2.min.js        jquery_form.js        wysiwyg.js        wysiwyg-settings.js        wysiwyg-popup.js          Just put these files inside Scripts folder. Also put wysiwyg.css in your Content Folder and add the following folders in your project        addons        popups          Also create a empty folder Uploads to store the uploaded images. Next open wysiwyg.js and set your configuration                  // Images Directory        this.ImagesDir = "/addons/imagelibrary/images/";                // Popups Directory        this.PopupsDir = "/popups/";                // CSS Directory File        this.CSSFile = "/Content/wysiwyg.css";              Next create a simple View TextEditor.aspx inside View / Home Folder and add the folllowing HTML.        <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %>            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">        <html >            <head runat="server">                <title>TextEditor</title>                <script src="../../Scripts/wysiwyg.js" type="text/javascript"></script>                <script src="../../Scripts/wysiwyg-settings.js" type="text/javascript"></script>                <script type="text/javascript">                            WYSIWYG.attach('text', full);                            </script>            </head>            <body>                <% using (Html.BeginForm()){ %>                    <textarea id="text" name="test2" style="width:850px;height:200px;">                    </textarea>                    <input type="submit" value="submit" />                <%} %>            </body>        </html>                  Here i have just added a text area control and a submit button inside a form. Note the id of text area and WYSIWYG.attach function's first parameter is same and next to watch is the HomeController.cs        using System;        using System.Collections.Generic;        using System.Linq;        using System.Web;        using System.Web.Mvc;        using System.IO;        namespace HtmlTextEditor.Controllers        {            [HandleError]            public class HomeController : Controller            {                public ActionResult Index()                {                    ViewData["Message"] = "Welcome to ASP.NET MVC!";                    return View();                }                    public ActionResult About()                {                                return View();                }                        public ActionResult TextEditor()                {                    return View();                }                [AcceptVerbs(HttpVerbs.Post)]                [ValidateInput(false)]                public ActionResult TextEditor(string test2)                {                    Session["html"] = test2;                            return RedirectToAction("Index");                }                        public ActionResult UploadImage()                {                    if (Request.Files[0].FileName != "")                    {                        Request.Files[0].SaveAs(Server.MapPath("~/Uploads/" + Path.GetFileName(Request.Files[0].FileName)));                        return Content(Url.Content("~/Uploads/" + Path.GetFileName(Request.Files[0].FileName)));                    }                    return Content("a");                }            }        }          So simple code, just save the posted Html into Session. Here the parameter of TextArea action is test2 which is same as textarea control name of TextArea.aspx View. Also note ValidateInputAttribute is false, so it's up to you to defends against XSS. Also there is an Action method which simply saves the file inside Upload Folder.          I am uploading the file using Jquery Form Plugin. Here is the code which is found in insert_image.html inside addons folder,        function ChangeImage() {            var myform=document.getElementById("formUpload");                    $(myform).ajaxSubmit({success: function(responseText){                insertImage(responseText);                        window.close();                }            });        }          and here is the Index View which simply renders the html of Editor which was saved in Session        <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>        <asp:Content ID="indexTitle" ContentPlaceHolderID="TitleContent" runat="server">            Home Page        </asp:Content>        <asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server">            <h2><%= Html.Encode(ViewData["Message"]) %></h2>            <p>                To learn more about ASP.NET MVC visit <a href="http://asp.net/mvc" title="ASP.NET MVC Website">http://asp.net/mvc</a>.            </p>            <%if (Session["html"] != null){                  Response.Write(Session["html"].ToString());            } %>                    </asp:Content>   Summary:          Hopefully you will enjoy this article. Just download the code and see the effect. From security point, you must handle the XSS attack your self. I had uploaded the sample application in http://www.speedfile.org/155076

• Posting from ASP.NET WebForms page to another URL

  - by hajan

  Few days ago I had a case when I needed to make FORM POST from my ASP.NET WebForms page to an external site URL. More specifically, I was working on implementing Simple Payment System (like Amazon, PayPal, MoneyBookers). The operator asks to make FORM POST request to a given URL in their website, sending parameters together with the post which are computed on my application level (access keys, secret keys, signature, return-URL… etc). So, since we are not allowed nesting another form inside the <form runat=”server”> … </form>, which is required because other controls in my ASPX code work on server-side, I thought to inject the HTML and create FORM with method=”POST”. After making some proof of concept and testing some scenarios, I’ve concluded that I can do this very fast in two ways: Using jQuery to create form on fly with the needed parameters and make submit() Using HttpContext.Current.Response.Write to write the form on server-side (code-behind) and embed JavaScript code that will do the post Both ways seemed fine. 1. Using jQuery to create FORM html code and Submit it. Let’s say we have ‘PAY NOW’ button in our ASPX code: <asp:Button ID="btnPayNow" runat="server" Text="Pay Now" /> Now, if we want to make this button submit a FORM using POST method to another website, the jQuery way should be as follows: <script src="http://ajax.aspnetcdn.com/ajax/jquery/jquery-1.5.1.js" type="text/javascript"></script> <script type="text/javascript">     $(function () {         $("#btnPayNow").click(function (event) {             event.preventDefault();             //construct htmlForm string             var htmlForm = "<form id='myform' method='POST' action='http://www.microsoft.com'>" +                 "<input type='hidden' id='name' value='hajan' />" +             "</form>";             //Submit the form             $(htmlForm).appendTo("body").submit();         });     }); </script> Yes, as you see, the code fires on btnPayNow click. It removes the default button behavior, then creates htmlForm string. After that using jQuery we append the form to the body and submit it. Inside the form, you can see I have set the htttp://www.microsoft.com URL, so after clicking the button you should be automatically redirected to the Microsoft website (just for test, of course for Payment I’m using Operator's URL). 2. Using HttpContext.Current.Response.Write to write the form on server-side (code-behind) and embed JavaScript code that will do the post The C# code behind should be something like this: public void btnPayNow_Click(object sender, EventArgs e) {     string Url = "http://www.microsoft.com";     string formId = "myForm1";     StringBuilder htmlForm = new StringBuilder();     htmlForm.AppendLine("<html>");     htmlForm.AppendLine(String.Format("<body onload='document.forms[\"{0}\"].submit()'>",formId));     htmlForm.AppendLine(String.Format("<form id='{0}' method='POST' action='{1}'>", formId, Url));     htmlForm.AppendLine("<input type='hidden' id='name' value='hajan' />");     htmlForm.AppendLine("</form>");     htmlForm.AppendLine("</body>");     htmlForm.AppendLine("</html>");     HttpContext.Current.Response.Clear();     HttpContext.Current.Response.Write(htmlForm.ToString());     HttpContext.Current.Response.End();             } So, with this code we create htmlForm string using StringBuilder class and then just write the html to the page using HttpContext.Current.Response.Write. The interesting part here is that we submit the form using JavaScript code: document.forms["myForm1"].submit() This code runs on body load event, which means once the body is loaded the form is automatically submitted. Note: In order to test both solutions, create two applications on your web server and post the form from first to the second website, then get the values in the second website using Request.Form[“input-field-id”] I hope this was useful post for you.
