Event-based interaction between two custom classes

- by Antenka

Hello everybody. I have such problem: I have 2 custom components, which have their own nesting hierarchy ... One is container for another. I have to "familiarize them" with each other. The way I'm trying to achieve that is using global events (one side is firing and the other one is catching): Application.application.addEventListener("Hello", function (data:Event):void{ // .. some actions }); //and Application.application.dispatchEvent(new Event(Hello)); Everything is pretty good, but there's one thingy .. when I'm trying to catch the event, I can't access the class, who is catching it. E.g.: Container fires the event. Child caughts it. Then should be created the connection between container and it's child. BUT, the only thing I could acheive is passing a reference to the Container in the DynamicEvent. Is there any chance that I could access the child at the event-handler function. Or maybe there's more elegant way to solve this problem ... Any help would be greately appreciated :)

URL Rewrite ASP.net

- by wandos

i have an asp.net website where i need to use URL re-write so i have written an HTTP module and i have implemented it and it works correctly the only problem is when the page redirect to its corresponding address the images and the styles are not loaded. here is the http module: // Your BeginRequest event handler. private void Application_BeginRequest(Object source, EventArgs e) { HttpApplication application = (HttpApplication)source; string URL = application.Request.Url.ToString(); //int pid = Convert.ToInt32(application.Request.QueryString["pid"]); if ((URL.ToLower().Contains(".aspx")) || (URL.ToLower().Contains(".js")) || (URL.ToLower().Contains(".css")) || (URL.ToLower().Contains(".gif")) || (URL.ToLower().Contains(".png")) || (URL.ToLower().Contains(".jpeg")) || (URL.ToLower().Contains(".jpe")) || (URL.ToLower().Contains(".jpg")) || (URL.ToLower().Contains(".ashx"))) return; else { string mname = URL.Substring(URL.LastIndexOf("/") + 1).ToString(); Merchand ms = merchantDB.GetMerchant(mname); HttpContext context = application.Context; if (ms != null) { string url = "~/pages/Merchant.aspx?mid=" + ms.MerchandID + "&catid=" + ms.MainCategory + "&subcatid=0"; context.RewritePath(VirtualPathUtility.ToAppRelative(url)); } else { //(""); string url = "~/pages/default.aspx"; context.RewritePath(VirtualPathUtility.ToAppRelative(url)); } } } when i open the page from it normal URL it opens fine, but when i use the url rewrite it open but with out images or styles. when i open firebug i get an error that the css and the javascript are not found

Automated browser testing: How to test JavaScript in web pages?

- by Dave

I am trying to write an application that will test a series of web-pages programmatically. The web pages being tested have JavaScript embedded within them which alter the structure of the HTML when they complete execution. It is then the goal to take the final HTML (post-execution of the embedded JavaScript) and compare it against a known output. Essentially, the Input --- Output for the test application is: URL ---[retrieve HTML]--- HTML ---[execute JS, then compare]--- PASS/FAIL Here is the challenge: I have been unable to find a solution that is able to take the HTML I retrieve from the URL and process the JavaScript, as a browser would, and generate the final HTML a user might see from "View Source" on the same page within the browser. It would be very surprising if this sort of approach has not been made before, so I'm hoping someone out there knows of a fitting solution for this application/problem? If at all possible, I'm hoping for a solution that integrates with .NET (I've tried using the WebBrowser, with no luck). However, if there is an existing 3rd party application that can do exactly this, that would be quite acceptable. Thanks in advance for the suggestions! Dave

Globally define parts of virtualhost definition to reduce redundancy

- by user1428900

I have setup an apache server and this apache server points to a bunch of virtualhosts. The definition of the virtualhosts are as follows, <VirtualHost *:80> ServerName <url> RewriteEngine on ReWriteCond %{SERVER_PORT} !^443$ RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R,L] # Enable client-side caching of resources ExpiresActive On ExpiresByType image/png "now plus 48 hours" ExpiresByType image/jpeg "now plus 48 hours" ExpiresByType image/gif "now plus 48 hours" ExpiresByType application/javascript "now plus 48 hours" ExpiresByType application/x-javascript "now plus 48 hours" ExpiresByType text/javascript "now plus 48 hours" ExpiresByType text/css "now plus 48 hours" </VirtualHost> . . . <VirtualHost *:80> ServerName <url> RewriteEngine on ReWriteCond %{SERVER_PORT} !^443$ RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R,L] # Enable client-side caching of resources ExpiresActive On ExpiresByType image/png "now plus 48 hours" ExpiresByType image/jpeg "now plus 48 hours" ExpiresByType image/gif "now plus 48 hours" ExpiresByType application/javascript "now plus 48 hours" ExpiresByType application/x-javascript "now plus 48 hours" ExpiresByType text/javascript "now plus 48 hours" ExpiresByType text/css "now plus 48 hours" </VirtualHost> I have a ton of virtual host definitions similar to the examples shown above. Since, most of the definitions other than the ServerName are the same, I was wondering if there was a way to define these common definitions globally. I am new to apache configuration and I felt that as the number of virtualhost definitions increase my configuration file becomes longer and redundant.

Error : 'java' is not recognized as an internal or external command, operable program or batch file.

- by Setu

I have my application online on the Google Apps Engine. When I deploy this application, this error is generated. I am using Netbeans 6.9. My jdk is installed at : "C:\Program Files\Java\jdk1.6.0_23\". I have installed Google App Engine for Java. This application is getting deployed & run on localhost very well. I am also able to start Google App Engine Server. I have set Environment variables as : 1) classpath : C:\Program Files\Java\jdk1.6.0_23\bin; 2) path : C:\Program Files\Java\jdk1.6.0_23\bin; 3) JAVA_HOME : C:\Program Files\Java\jdk1.6.0_23\bin; 4) include : C:\Program Files\Java\jdk1.6.0_23\include; 5) lib : C:\Program Files\Java\jdk1.6.0_23\lib; However, in system32, I am not finding java.exe, javac.exe or javawc.exe. Also, while running this : 1) java.exe 2) javac.exe 3) java -version from Command Line, they give proper output. How do I make my application properly deployed ?

Log4j Logging to the Wrong Directory

- by John

I have a relatively complex log4j.xml configuration file with many appenders. Some machines the application runs on need a separate log directory, which is actually a mapped network drive. To get around this, we embed a system property as part of the filename in order to specify the directory. Here is an example: The "${user.dir}" part is set as a system property on each system, and is normally set to the root directory of the application. On some systems, this location is not the root of the application. The problem is that there is always one appender where this is not set, and the file appears not to write to the mapped drive. The rest of the appenders do write to the correct location per the system property. As a unit test, I set up our QA lab to hard-code the values for the appender above, and it worked: however, a different appender will then append to the wrong file. The mis-logged file is always the same for a given configuration: it is not a random file each time. My best educated guess is that there is a HashMap somewhere containing these appenders, and for some reason, the first one retrieved from the map does not have the property set. Our application does have custom system properties loading: the main() method loads a properties file and calls into System.setProperties(). My first instinct was to check the static initialization order, and to ensure the controller class with the main method does not call into log4j (directly or indirectly) before setting the properties just in case this was interfering with log4j's own initialization. Even removing all vestiges of log4j from the initialization logic, this error condition still occurs.

Android - How to decide wether to run a Service in a separate Process?

- by pableu

I am working on an Android application that collects sensor data over the course of multiple hours. For that, we have a Service that collects the Sensor Data (e.g. Acceleration, GPS, ..), does some processing and stores them remotely on a server. Currently, this Service runs in a separate process (using android:service=":background" in the manifest). This complicates the communication between the Activities and the Service, but my predecessors created the Application this way because they thought that separating the Service from the Activities would make it more stable. I would like some more factual reasons for the effort of running a separate process. What are the advantages? Does it really run more stable? Is the Service less likely to be killed by the OS (to free up resources) if it's in a separate process? Our Application uses startForeground() and friends to minimize the chance of getting killed by the OS. The Android docs are not very specific about this, the mostly state that it depends on the Application's purpose ;-) TL;DR What are objective reasons to put a long-running Service in a separate process (in Android)?

Rails using plural table names even though I told it to use singular

- by Jason Swett

I tried to run rake test:profile and I got this error: ... Table 'mcif2.accounts' doesn't exist: DELETE FROM `accounts` I know accounts doesn't exist. It's called account. I know Rails uses plural table names by default but here's what my config/environment.rb looks like: # Load the rails application require File.expand_path('../application', __FILE__) # Initialize the rails application McifRails::Application.initialize! ActiveRecord::Base.pluralize_table_names = false And here's what db/schema.rb looks like: ActiveRecord::Schema.define(:version => 0) do create_table "account", :force => true do |t| t.integer "customer_id", :limit => 8, :null => false t.string "account_number", :null => false t.integer "account_type_id", :limit => 8 t.date "open_date", :null => false So I don't understand why Rails still wants to call it accounts sometimes. Any ideas? If it helps give any clues at all, here are the results of grep -ir 'accounts' *.

Internet Explorer 6 and 7: floated elements expand to 100% width when they contain a child element f

- by Paul D. Waite

I've got a parent div floated left, with two child divs that I need to float right. The parent div should (if I understand the spec correctly) be as wide as needed to contain the child divs, and this is how it behaves in Firefox et al. In IE, the parent div expands to 100% width. This seems to be an issue with floated elements that have children floated right. Test page: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> <head> <title>Float test</title> </head> <body> <div style="border-top:solid 10px #0c0;float:left;"> <div style="border-top:solid 10px #00c;float:right;">Tester 1</div> <div style="border-top:solid 10px #c0c;float:right;">Tester 2</div> </div> </body> </html> Unfortunately I can't fix the width of the child divs, so I can't set a fixed width on the parent. Is there a CSS-only workaround to make the parent div as wide as the child divs?

Pre-filtering and shaping OData feeds using WCF Data Services and the Entity Framework - Part 1

- by rajbk

The Open Data Protocol, referred to as OData, is a new data-sharing standard that breaks down silos and fosters an interoperative ecosystem for data consumers (clients) and producers (services) that is far more powerful than currently possible. It enables more applications to make sense of a broader set of data, and helps every data service and client add value to the whole ecosystem. WCF Data Services (previously known as ADO.NET Data Services), then, was the first Microsoft technology to support the Open Data Protocol in Visual Studio 2008 SP1. It provides developers with client libraries for .NET, Silverlight, AJAX, PHP and Java. Microsoft now also supports OData in SQL Server 2008 R2, Windows Azure Storage, Excel 2010 (through PowerPivot), and SharePoint 2010. Many other other applications in the works. * This post walks you through how to create an OData feed, define a shape for the data and pre-filter the data using Visual Studio 2010, WCF Data Services and the Entity Framework. A sample project is attached at the bottom of Part 2 of this post. Pre-filtering and shaping OData feeds using WCF Data Services and the Entity Framework - Part 2 Create the Web Application File –› New –› Project, Select “ASP.NET Empty Web Application” Add the Entity Data Model Right click on the Web Application in the Solution Explorer and select “Add New Item..” Select “ADO.NET Entity Data Model” under "Data”. Name the Model “Northwind” and click “Add”. In the “Choose Model Contents”, select “Generate Model From Database” and click “Next” Define a connection to your database containing the Northwind database in the next screen. We are going to expose the Products table through our OData feed. Select “Products” in the “Choose your Database Object” screen. Click “Finish”. We are done creating our Entity Data Model. Save the Northwind.edmx file created. Add the WCF Data Service Right click on the Web Application in the Solution Explorer and select “Add New Item..” Select “WCF Data Service” from the list and call the service “DataService” (creative, huh?). Click “Add”. Enable Access to the Data Service Open the DataService.svc.cs class. The class is well commented and instructs us on the next steps. public class DataService : DataService< /* TODO: put your data source class name here */ > { // This method is called only once to initialize service-wide policies. public static void InitializeService(DataServiceConfiguration config) { // TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc. // Examples: // config.SetEntitySetAccessRule("MyEntityset", EntitySetRights.AllRead); // config.SetServiceOperationAccessRule("MyServiceOperation", ServiceOperationRights.All); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; } } Replace the comment that starts with “/* TODO:” with “NorthwindEntities” (the entity container name of the Model we created earlier). WCF Data Services is initially locked down by default, FTW! No data is exposed without you explicitly setting it. You have explicitly specify which Entity sets you wish to expose and what rights are allowed by using the SetEntitySetAccessRule. The SetServiceOperationAccessRule on the other hand sets rules for a specified operation. Let us define an access rule to expose the Products Entity we created earlier. We use the EnititySetRights.AllRead since we want to give read only access. Our modified code is shown below. public class DataService : DataService<NorthwindEntities> { public static void InitializeService(DataServiceConfiguration config) { config.SetEntitySetAccessRule("Products", EntitySetRights.AllRead); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; } } We are done setting up our ODataFeed! Compile your project. Right click on DataService.svc and select “View in Browser” to see the OData feed. To view the feed in IE, you must make sure that "Feed Reading View" is turned off. You set this under Tools -› Internet Options -› Content tab. If you navigate to “Products”, you should see the Products feed. Note also that URIs are case sensitive. ie. Products work but products doesn’t. Filtering our data OData has a set of system query operations you can use to perform common operations against data exposed by the model. For example, to see only Products in CategoryID 2, we can use the following request: /DataService.svc/Products?$filter=CategoryID eq 2 At the time of this writing, supported operations are $orderby, $top, $skip, $filter, $expand, $format†, $select, $inlinecount. Pre-filtering our data using Query Interceptors The Product feed currently returns all Products. We want to change that so that it contains only Products that have not been discontinued. WCF introduces the concept of interceptors which allows us to inject custom validation/policy logic into the request/response pipeline of a WCF data service. We will use a QueryInterceptor to pre-filter the data so that it returns only Products that are not discontinued. To create a QueryInterceptor, write a method that returns an Expression<Func<T, bool>> and mark it with the QueryInterceptor attribute as shown below. [QueryInterceptor("Products")] public Expression<Func<Product, bool>> OnReadProducts() { return o => o.Discontinued == false; } Viewing the feed after compilation will only show products that have not been discontinued. We also confirm this by looking at the WHERE clause in the SQL generated by the entity framework. SELECT [Extent1].[ProductID] AS [ProductID], ... ... [Extent1].[Discontinued] AS [Discontinued] FROM [dbo].[Products] AS [Extent1] WHERE 0 = [Extent1].[Discontinued] Other examples of Query/Change interceptors can be seen here including an example to filter data based on the identity of the authenticated user. We are done pre-filtering our data. In the next part of this post, we will see how to shape our data. Pre-filtering and shaping OData feeds using WCF Data Services and the Entity Framework - Part 2 Foot Notes * http://msdn.microsoft.com/en-us/data/aa937697.aspx † $format did not work for me. The way to get a Json response is to include the following in the request header “Accept: application/json, text/javascript, */*” when making the request. This is easily done with most JavaScript libraries.

Getting Started with ASP.NET Membership, Profile and RoleManager

- by Ben Griswold

A new ASP.NET MVC project includes preconfigured Membership, Profile and RoleManager providers right out of the box. Try it yourself – create a ASP.NET MVC application, crack open the web.config file and have a look. First, you’ll find the ApplicationServices database connection: <connectionStrings> <add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/> </connectionStrings> Notice the connection string is referencing the aspnetdb.mdf database hosted by SQL Express and it’s using integrated security so it’ll just work for you without having to call out a specific database login or anything. Scroll down the file a bit and you’ll find each of the three noted sections: <membership> <providers> <clear/> <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" passwordStrengthRegularExpression="" applicationName="/" /> </providers> </membership> <profile> <providers> <clear/> <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="ApplicationServices" applicationName="/" /> </providers> </profile> <roleManager enabled="false"> <providers> <clear /> <add connectionStringName="ApplicationServices" applicationName="/" name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> <add applicationName="/" name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> </providers> </roleManager> Really. It’s all there. Still don’t believe me. Run the application, walk through the registration process and finally login and logout. Completely functional – and you didn’t have to do a thing! What else? Well, you can manage your users via the Configuration Manager which is hiding in Visual Studio behind Projects > ASP.NET Configuration. The ASP.NET Web Site Administration Tool isn’t MVC-specific (neither is the Membership, Profile or RoleManager stuff) but it’s neat and I hardly ever see anyone using it. Here you can set up and edit users, roles, and set access permissions for your site. You can manage application settings, establish your SMTP settings, configure debugging and tracing, define default error page and even take your application offline. The UI is rather plain-Jane but it works great. And here’s the best of all. Let’s say you, like most of us, don’t want to run your application on top of the aspnetdb.mdf database. Let’s suppose you want to use your own database and you’d like to add the membership stuff to it. Well, that’s easy enough. Take a look inside your [drive:]\%windir%\Microsoft.Net\Framework\v2.0.50727\ folder. Here you’ll find a bunch of files. If you were to run the InstallCommon.sql, InstallMembership.sql, InstallRoles.sql and InstallProfile.sql files against the database of your choices, you’d be installing the same membership, profile and role artifacts which are found in the aspnet.db to your own database. Too much trouble? Okay. Run [drive:]\%windir%\Microsoft.Net\Framework\v2.0.50727\aspnet_regsql.exe from the command line instead. This will launch the ASP.NET SQL Server Setup Wizard which walks you through the installation of those same database objects into the new or existing database of your choice. You may not always have the luxury of using this tool on your destination server, but you should use it whenever you can. Last tip: don’t forget to update the ApplicationServices connectionstring to point to your custom database after the setup is complete. At the risk of sounding like a smarty, everything I’ve mentioned in this post has been around for quite a while. The thing is that not everyone has had the opportunity to use it. And it makes sense. I know I’ve worked on projects which used custom membership services. Why bother with the out-of-the-box stuff, right? And the .NET framework is so massive, who can know it all. Well, eventually you might have a chance to architect your own solution using any implementation you’d like or you will have the time to play around with another aspect of the framework. When you do, think back to this post.

User Experience Highlights in PeopleSoft and PeopleTools: Direct from Jeff Robbins

- by mvaughan

By Kathy Miedema, Oracle Applications User Experience This is the fifth in a series of blog posts on the user experience (UX) highlights in various Oracle product families. The last posted interview was with Nadia Bendjedou, Senior Director, Product Strategy on upcoming Oracle E-Business Suite user experience highlights. You’ll see themes around productivity and efficiency, and get an early look at the latest mobile offerings coming through these product lines. Today’s post is on the user experience in PeopleSoft and PeopleTools. To learn more about what’s ahead, attend PeopleSoft or PeopleTools OpenWorld presentations.This interview is with Jeff Robbins, Senior Director, PeopleSoft Development. Jeff Robbins Q: How would you describe the vision you have for the user experience of PeopleSoft?A: Intuitive – Specifically, customers use PeopleSoft to help their employees do their day-to-day work, and the UI (user interface) has been helpful and assistive in that effort. If it’s not obvious what they need to do a task, then the UI isn’t working. So the application needs to make it simple for users to find information they need, complete a task, do all the things they are responsible for, and it really helps when the UI just makes sense. Productive – PeopleSoft is a tool used to support people to do their work, and a lot of users are measured by how much work they’re able to get done per hour, per day, etc. The UI needs to help them be as productive as possible, and can’t make them waste time or energy. The UI needs to reflect the type of work necessary for a task -- if it's data entry, the UI needs to assist the user to get information into the system. For analysts, the UI needs help users assess or analyze information in a particular way. Innovative – The concept of the UI being innovative is something we’ve been working on for years. It’s not just that we want to be seen as innovative, the fact is that companies are asking their employees to do more than they’ve ever asked before. More often companies want to roll out processes as employee or manager self-service, where an employee is responsible to review and maintain their own data. So we’ve had to reinvent, and ask, “How can we modify the ways an employee interacts with our applications so that they can be more productive and efficient – even with tasks that are entirely unfamiliar?” Our focus on innovation has forced us to design new ways for users to interact with the entire application.Q: How are the UX features you have delivered so far resonating with customers? A: Resonating very well. We’re hearing tremendous responses from users, managers, decision-makers -- who are very happy with the improved user experience. Many of the individual features resonate well. Some have really hit home, others are better than they used to be but show us that there’s still room for improvement.A couple innovations really stand out; features that have a significant effect on how users interact with PeopleSoft.First, the deployment of PeopleSoft in a way that’s more like a consumer website with the PeopleSoft Home page and Dashboards. This new approach is very web-centric, where users feel they’re coming to a website rather than logging into an enterprise application. There’s lots of information from all around the organization collected in a way that feels very familiar to users. In order to do your job, you can come to this web site rather than having to learn how to log into an application and figure out a complicated menu. Companies can host these really rich web sites for employees that are home pages for accessing critical tasks and information. The UI elements of incorporating search into the whole navigation process is another hit. Rather than having to log in and choose a task from a menu, users come to the web site and begin a task by simply searching for data: themselves, another employee, a customer record, whatever. The search results include the data along with a set of actions the user might take, completely eliminating the need to hunt through a complicated system menu. Search-centric navigation is really sitting well with customers who are trying to deploy an intuitive set of systems. Q: Are any UX highlights more popular than you expected them to be? A: We introduced a feature called Pivot Grid in the last release, which is a combination of an interactive grid, like an Excel Pivot Table, along with a dynamic visual chart that automatically graphs the data. I wasn’t certain at first how extensively this would be used. It looked like an innovative tool, but it wasn’t clear how it would be incorporated in business process applications. The fact is that everyone who sees Pivot Grids is thrilled with that kind of interactivity. It reflects the amount of analytical thinking customers are asking employees to do. Employees can’t just enter data any more. They must interact with it, analyze it, and make decisions. Pivot Grids fit into this way of working. Q: What can you tell us about PeopleSoft’s mobile offerings?A: A lot of customers are finding that mobile is the chief priority in their organization. They tell us they want their employees to be able to access company information from their mobile devices. Of course, not everyone has the same requirements, so we’re working to make sure we can help our customers accomplish what they’re trying to do. We’ve already delivered a number of mobile features. For instance, PeopleSoft home pages, dashboards and workcenters all work well on an iPad, straight out of the box. We’ve delivered a number of key functions and tasks for mobile workers – those who are responsible for using a mobile device to manage inventory, for example. Customers tell us they also need a holistic strategy, one that allows their employees to access nearly every task from a mobile device. While we don’t expect users to do extensive data entry from their smartphone, it makes sense that they have access to company information and systems while away from their desk. That’s where our strategy is going now. We plan to unveil a number of new mobile offerings at OpenWorld. Some will be available then, some shortly after. Q: What else are you working on now that you think is going to be exciting to customers at Oracle OpenWorld?A: Our next release -- the big thing is PeopleSoft 9.2, and we’ll be talking about the huge amount of work that’s gone into the next versions. A new toolset, 8.53, will be coming, and there’s a lot to talk about there, and the next generation of PeopleSoft 9.2. We have a ton of new stuff coming.Q: What do you want PeopleSoft customers to know? A: We have been focusing on the user experience in PeopleSoft as a very high priority for the last 4 years, and it’s had interesting effects. One thing is that the application is better, more usable. We’ve made visible improvements. Another aspect is that in customers’ minds, the PeopleSoft brand is being reinvigorated. Customers invested in PeopleSoft years ago, and then they weren’t sure where PeopleSoft was going. This investment in the UI and overall user experience keeps PeopleSoft current, innovative and fresh. Customers are able to take advantage of a lot of new features, even on the older applications, simply by upgrading their PeopleTools. The interest in that ability has been tremendous. Knowing they have a lot of these features available -- right now, that’s pretty huge. There’s been a tremendous amount of positive response, just on the fact that we’re focusing on the user experience.

Observations in Migrating from JavaFX Script to JavaFX 2.0

- by user12608080

Observations in Migrating from JavaFX Script to JavaFX 2.0 Introduction Having been available for a few years now, there is a decent body of work written for JavaFX using the JavaFX Script language. With the general availability announcement of JavaFX 2.0 Beta, the natural question arises about converting the legacy code over to the new JavaFX 2.0 platform. This article reflects on some of the observations encountered while porting source code over from JavaFX Script to the new JavaFX API paradigm. The Application The program chosen for migration is an implementation of the Sudoku game and serves as a reference application for the book JavaFX – Developing Rich Internet Applications. The design of the program can be divided into two major components: (1) A user interface (ideally suited for JavaFX design) and (2) the puzzle generator. For the context of this article, our primary interest lies in the user interface. The puzzle generator code was lifted from a sourceforge.net project and is written entirely in Java. Regardless which version of the UI we choose (JavaFX Script vs. JavaFX 2.0), no code changes were required for the puzzle generator code. The original user interface for the JavaFX Sudoku application was written exclusively in JavaFX Script, and as such is a suitable candidate to convert over to the new JavaFX 2.0 model. However, a few notable points are worth mentioning about this program. First off, it was written in the JavaFX 1.1 timeframe, where certain capabilities of the JavaFX framework were as of yet unavailable. Citing two examples, this program creates many of its own UI controls from scratch because the built-in controls were yet to be introduced. In addition, layout of graphical nodes is done in a very manual manner, again because much of the automatic layout capabilities were in flux at the time. It is worth considering that this program was written at a time when most of us were just coming up to speed on this technology. One would think that having the opportunity to recreate this application anew, it would look a lot different from the current version. Comparing the Size of the Source Code An attempt was made to convert each of the original UI JavaFX Script source files (suffixed with .fx) over to a Java counterpart. Due to language feature differences, there are a small number of source files which only exist in one version or the other. The table below summarizes the size of each of the source files. JavaFX Script source file Number of Lines Number of Character JavaFX 2.0 Java source file Number of Lines Number of Characters ArrowKey.java 6 72 Board.fx 221 6831 Board.java 205 6508 BoardNode.fx 446 16054 BoardNode.java 723 29356 ChooseNumberNode.fx 168 5267 ChooseNumberNode.java 302 10235 CloseButtonNode.fx 115 3408 CloseButton.java 99 2883 ParentWithKeyTraversal.java 111 3276 FunctionPtr.java 6 80 Globals.java 20 554 Grouping.fx 8 140 HowToPlayNode.fx 121 3632 HowToPlayNode.java 136 4849 IconButtonNode.fx 196 5748 IconButtonNode.java 183 5865 Main.fx 98 3466 Main.java 64 2118 SliderNode.fx 288 10349 SliderNode.java 350 13048 Space.fx 78 1696 Space.java 106 2095 SpaceNode.fx 227 6703 SpaceNode.java 220 6861 TraversalHelper.fx 111 3095 Total 2,077 79,127 2531 87,800 A few notes about this table are in order: The number of lines in each file was determined by running the Unix ‘wc –l’ command over each file. The number of characters in each file was determined by running the Unix ‘ls –l’ command over each file. The examination of the code could certainly be much more rigorous. No standard formatting was performed on these files. All comments however were deleted. There was a certain expectation that the new Java version would require more lines of code than the original JavaFX script version. As evidenced by a count of the total number of lines, the Java version has about 22% more lines than its FX Script counterpart. Furthermore, there was an additional expectation that the Java version would be more verbose in terms of the total number of characters. In fact the preceding data shows that on average the Java source files contain fewer characters per line than the FX files. But that's not the whole story. Upon further examination, the FX Script source files had a disproportionate number of blank characters. Why? Because of the nature of how one develops JavaFX Script code. The object literal dominates FX Script code. Its not uncommon to see object literals indented halfway across the page, consuming lots of meaningless space characters. RAM consumption Not the most scientific analysis, memory usage for the application was examined on a Windows Vista system by running the Windows Task Manager and viewing how much memory was being consumed by the Sudoku version in question. Roughly speaking, the FX script version, after startup, had a RAM footprint of about 90MB and remained pretty much the same size. The Java version started out at about 55MB and maintained that size throughout its execution. What About Binding? Arguably, the most striking observation about the conversion from JavaFX Script to JavaFX 2.0 concerned the need for data synchronization, or lack thereof. In JavaFX Script, the primary means to synchronize data is via the bind expression (using the “bind” keyword), and perhaps to a lesser extent it’s “on replace” cousin. The bind keyword does not exist in Java, so for JavaFX 2.0 a Data Binding API has been introduced as a replacement. To give a feel for the difference between the two versions of the Sudoku program, the table that follows indicates how many binds were required for each source file. For JavaFX Script files, this was ascertained by simply counting the number of occurrences of the bind keyword. As can be seen, binding had been used frequently in the JavaFX Script version (and does not take into consideration an additional half dozen or so “on replace” triggers). The JavaFX 2.0 program achieves the same functionality as the original JavaFX Script version, yet the equivalent of binding was only needed twice throughout the Java version of the source code. JavaFX Script source file Number of Binds JavaFX Next Java source file Number of “Binds” ArrowKey.java 0 Board.fx 1 Board.java 0 BoardNode.fx 7 BoardNode.java 0 ChooseNumberNode.fx 11 ChooseNumberNode.java 0 CloseButtonNode.fx 6 CloseButton.java 0 CustomNodeWithKeyTraversal.java 0 FunctionPtr.java 0 Globals.java 0 Grouping.fx 0 HowToPlayNode.fx 7 HowToPlayNode.java 0 IconButtonNode.fx 9 IconButtonNode.java 0 Main.fx 1 Main.java 0 Main_Mobile.fx 1 SliderNode.fx 6 SliderNode.java 1 Space.fx 0 Space.java 0 SpaceNode.fx 9 SpaceNode.java 1 TraversalHelper.fx 0 Total 58 2 Conclusions As the JavaFX 2.0 technology is so new, and experience with the platform is the same, it is possible and indeed probable that some of the observations noted in the preceding article may not apply across other attempts at migrating applications. That being said, this first experience indicates that the migrated Java code will likely be larger, though not extensively so, than the original Java FX Script source. Furthermore, although very important, it appears that the requirements for data synchronization via binding, may be significantly less with the new platform.

Downloads, documentation links and more information on the Oracle SOA Suite available on the SOA Suite OTN page and as always, we welcome your feedback on the SOA OTN forum. New in Oracle SOA Suite in this release BPEL Component BPEL 2.0 support in JDeveloper The BPEL editor in JDeveloper now generates BPEL 2.0 code and introduces several new activities. Augmented XML variables auto-initialization capabilities The XML variable auto-initialization capabilities have been enhanced to support two need additional use cases: to initialize the to-spec node if it doesn't exist during the rule and to initialize array elements. New Assign Activity dialog The new Assign Activity supports the same drag & drop paradigm used for the XSLT mapper, greatly streamlining the task of assigning multiple variables. Mediator Component Time window parameter for the resequencer This new parameter lets users initiate a best-effort resequencing based on a time window rather than a number of messages. Support for attachments in the Mediator assign dialog The Mediator assign dialog now supports attachment, enabling usage of the Mediator to transmit attachments even if source and target schemas are different. Adapters & Bindings ChunkSize property added to the File Adapter header properties The ChunkSize property of the File Adapter is now available as a header property, allowing in-process modification of the value for this property. Improved support for distributed WLS JMS topics though automatic rebalancing of listeners The JMS Adapter has been enhanced to subscribe to administrative events from WLS JMS. Based on these events, it dynamically rebalances listeners when there are changes to the members of a local or remote WLS JMS distributed destination. JDeveloper configuration wizard for custom JCA adapters A new wizard is available in JDeveloper to configure custom-built adapters Administration & Enterprise Manager Enhanced purging capabilities to manage database growth Historical instance data can now be purged using three different strategies: batch script, scheduled batch script or data partitioning. Asynchronous bulk instance deletion in Enterprise Manager Bulk deletion of instances in Enterprise Manager now executes as an asynchronous operation in Enterprise Manager, returning control to the user as soon as the action has been submitted and acknowledged. B2B Ability to schedule partner downtime This feature allows trading partners to notify each other about planned downtime and to delay delivery of messages during that period. Message sequencing B2B now supports both inbound and outbound message sequencing. Simplified BAM integration with B2B B2B ships with various pre-configured artifacts to simplify monitoring in BAM. Instance Message Java API for B2B The new instance message Java API supports programmatic access to B2B instance message data. Oracle Service Bus (OSB) Certification of the File and FTP JCA Adapters The File and FTP JCA adapters are now certified for use with Oracle Service Bus (in addition to the native transports). Security enhancements Oracle Service Bus now supports SAML 2.0 as well as the OWSM authorization policies. Check the Oracle Service Bus 11.1.1.4 Release Notes for a complete list of new features. Installation, Hot-Pluggability & Certifications Ability to run Oracle SOA Suite on IBM WebSphere Application Server Oracle SOA Suite can now be deployed on IBM WebSphere Application Server Network Deployment (ND) 7.0.11 and IBM WebSphere Application Server 7.0.11. Single JVM developer installation template Oracle SOA Suite can now be targeted to the WebLogic admin server - there is no requirement to also have a managed server. This topology is intended to minimize the memory foorprint of development environments. This is in addition to the list of supported browsers, operating systems and databases already certified in prior releases. Complex Event Processing (CEP) IDE enhancements This release introduces several enhancements to the development IDE, such as adapter wizards and event-type repository. CQL enhancements CQL enhancements include JDBC data cartridges and parametrized queries. Tracing and injecting events in the Event Processing Network (EPN) In the development environment you can now trace and inject events. Check the Oracle CEP 11.1.1.4 Release Notes for a complete list of new features.

Quartz.Net Windows Service Configure Logging

- by Tarun Arora

In this blog post I’ll be covering, Logging for Quartz.Net Windows Service 01 – Why doesn’t Quartz.Net Windows Service log by default 02 – Configuring Quartz.Net windows service for logging to eventlog, file, console, etc 03 – Results: Logging in action If you are new to Quartz.Net I would recommend going through, A brief Introduction to Quartz.net Walkthrough of Installing & Testing Quartz.Net as a Windows Service Writing & Scheduling your First HelloWorld job with Quartz.Net 01 – Why doesn’t Quartz.Net Windows Service log by default If you are trying to figure out why… The Quartz.Net windows service isn’t logging The Quartz.Net windows service isn’t writing anything to the event log The Quartz.Net windows service isn’t writing anything to a file How do I configure Quartz.Net windows service to use log4Net How do I change the level of logging for Quartz.Net Look no further, This blog post should help you answer these questions. Quartz.NET uses the Common.Logging framework for all of its logging needs. If you navigate to the directory where Quartz.Net Windows Service is installed (I have the service installed in C:\Program Files (x86)\Quartz.net, you can find out the location by looking at the properties of the service) and open ‘Quartz.Server.exe.config’ you’ll see that the Quartz.Net is already set up for logging to ConsoleAppender and EventLogAppender, but only ‘ConsoleAppender’ is set up as active. So, unless you have the console associated to the Quartz.Net service you won’t be able to see any logging. <log4net> <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender"> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d [%t] %-5p %l - %m%n" /> </layout> </appender> <appender name="EventLogAppender" type="log4net.Appender.EventLogAppender"> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d [%t] %-5p %l - %m%n" /> </layout> </appender> <root> <level value="INFO" /> <appender-ref ref="ConsoleAppender" />   </root> </log4net> Problem: In the configuration above Quartz.Net Windows Service only has ConsoleAppender active. So, no logging will be done to EventLog. More over the RollingFileAppender isn’t setup at all. So, Quartz.Net will not log to an application trace log file. 02 – Configuring Quartz.Net windows service for logging to eventlog, file, console, etc Let’s change this behaviour by changing the config file… In the below config file, I have added the RollingFileAppender. This will configure Quartz.Net service to write to a log file. (<appender name="GeneralLog" type="log4net.Appender.RollingFileAppender">) I have specified the location for the log file (<arg key="configFile" value="Trace/application.log.txt"/>) I have enabled the EventLogAppender and RollingFileAppender to be written to by Quartz. Net windows service Changed the default level of logging from ‘Info’ to ‘All’. This means all activity performed by Quartz.Net Windows service will be logged. You might want to tune this back to ‘Debug’ or ‘Info’ later as logging ‘All’ will produce too much data to the logs. (<level value="ALL"/>) Since I have changed the logging level to ‘All’, I have added applicationSetting to remove logging log4Net internal debugging. (<add key="log4net.Internal.Debug" value="false"/>) <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="quartz" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089" /> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> <sectionGroup name="common"> <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" /> </sectionGroup> </configSections> <common> <logging> <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4net"> <arg key="configType" value="INLINE" /> <arg key="configFile" value="Trace/application.log.txt"/> <arg key="level" value="ALL" /> </factoryAdapter> </logging> </common> <appSettings> <add key="log4net.Internal.Debug" value="false"/> </appSettings> <log4net> <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender"> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d [%t] %-5p %l - %m%n" /> </layout> </appender> <appender name="EventLogAppender" type="log4net.Appender.EventLogAppender"> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d [%t] %-5p %l - %m%n" /> </layout> </appender> <appender name="GeneralLog" type="log4net.Appender.RollingFileAppender"> <file value="Trace/application.log.txt"/> <appendToFile value="true"/> <maximumFileSize value="1024KB"/> <rollingStyle value="Size"/> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d{HH:mm:ss} [%t] %-5p %c - %m%n"/> </layout> </appender> <root> <level value="ALL" /> <appender-ref ref="ConsoleAppender" /> <appender-ref ref="EventLogAppender" /> <appender-ref ref="GeneralLog"/> </root> </log4net> </configuration> Note – Please ensure you restart the Quartz.Net Windows service for the config changes to be picked up by the service 03 – Results: Logging in action Once you start the Quartz.Net Windows Service up, the logging should be initiated to write all activities in the Console, EventLog and File… See screen shots below… Figure – Quartz.Net Windows Service logging all activity to the event log Figure – Quartz.Net Windows Service logging all activity to the application log file Where is the output from log4Net ConsoleAppender? As a default behaviour, the console isn't available in windows services, web services, windows forms. The output will simply be dismissed. Unless you are running the process interactively. Which you can do by firing up Quartz.Server.exe –i to see the output This was fourth in the series of posts on enterprise scheduling using Quartz.net, in the next post I’ll be covering troubleshooting why a scheduled task hasn’t fired on Quartz.net windows service. All Quartz.Net specific blog posts can listed here. Thank you for taking the time out and reading this blog post.

How you can extend Tasklists in Fusion Applications

- by Elie Wazen

In this post we describe the process of modifying and extending a Tasklist available in the Regional Area of a Fusion Applications UI Shell. This is particularly useful to Customers who would like to expose Setup Tasks (generally available in the Fusion Setup Manager application) in the various functional pillars workareas. Oracle Composer, the tool used to implement such extensions allows changes to be made at runtime. The example provided in this document is for an Oracle Fusion Financials page. Let us examine the case of a customer role who requires access to both, a workarea and its associated functional tasks, and to an FSM (setup) task. Both of these tasks represent ADF Taskflows but each is accessible from a different page. We will show how an FSM task is added to a Functional tasklist and made accessible to a user from within a single workarea, eliminating the need to navigate between the FSM application and the Functional workarea where transactions are conducted. In general, tasks in Fusion Applications are grouped in two ways: Setup tasks are grouped in tasklists available to implementers in the Functional Setup Manager (FSM). These Tasks are accessed by implementation users and in general do not represent daily operational tasks that fit into a functional business process and were consequently included in the FSM application. For these tasks, the primary organizing principle is precedence between tasks. If task "Manage Suppliers" has prerequisites, those tasks must precede it in a tasklist. Task Lists are organized to efficiently implement an offering. Tasks frequently performed as part of business process flows are made available as links in the tasklist of their corresponding menu workarea. The primary organizing principle in the menu and task pane entries is to group tasks that are generally accessed together. Customizing a tasklist thus becomes required for business scenarios where a task packaged under FSM as a setup task, is for a particular customer a regular maintenance task that is accessed for record updates or creation as part of normal operational activities and where the frequency of this access merits the inclusion of that task in the related operational tasklist A user with the role of maintaining Journals in General Ledger is also responsible for maintaining Chart of Accounts Mappings. In the Fusion Financials Product Family, Manage Journals is a task available from within the Journals Menu whereas Chart of Accounts Mapping is available via FSM under the Define Chart of Accounts tasklist Figure 1. The Manage Chart of Accounts Mapping Task in FSM Figure 2. The Manage Journals Task in the Task Pane of the Journals Workarea Our goal is to simplify cross task navigation and allow the user to access both tasks from a single tasklist on a single page without having to navigate to FSM for the Mapping task and to the Journals workarea for the Manage task. To accomplish that, we use Oracle Composer to customize the Journals tasklist by adding to it the Mapping task. Identify the Taskflow name and path of the FSM Task The first step in our process is to identify the underlying taskflow for the Manage Chart of Accounts Mappings task. We select to Setup and Maintenance from the Navigator to launch the FSM Application, and we query the task from Manage Tasklists and Tasks Figure 3. Task Details including Taskflow path The Manage Chart of Accounts Mapping Task Taskflow is: /WEB-INF/oracle/apps/financials/generalLedger/sharedSetup/coaMappings/ui/flow /CoaMappingsMainAreaFlow.xml#CoaMappingsMainAreaFlow We copy that value and use it later as a parameter to our new task in the customized Journals Tasklist. Customize the Journals Page A user with Administration privileges can start the run time customization directly from the Administration Menu of the Global Area. This customization is done at the Site level and once implemented becomes available to all users with access to the Journals Workarea. Figure 4. Customization Menu The Oracle Composer Window is displayed in the same browser and the Hierarchy of the page component is displayed and available for modification. Figure 5. Oracle Composer In the composer Window select the PanelFormLayout node and click on the Edit Button. Note that the selected component is simultaneously highlighted in the lower pane in the browser. In the Properties popup window, select the Tasks List and Task Properties Tab, where the user finds the hierarchy of the Tasklist and is able to Edit nodes or create new ones. src="https://blogs.oracle.com/FunctionalArchitecture/resource/TL5.jpg" Figure 6. The Tasklist in edit mode Add a Child Task to the Tasklist In the Edit Window the user will now create a child node at the desired level in the hierarchy by selecting the immediate parent node and clicking on the insert node button. This process requires four values to be set as described in Table 1 below. Parameter Value How to Determine the Value Focus View Id /JournalEntryPage This is the Focus View ID of the UI Shell where the Tasklist we want to customize is. A simple way to determine this value is to copy it from any of the Standard tasks on the Tasklist Label COA Mapping This is the Display name of the Task as it will appear in the Tasklist Task Type dynamicMain If the value is dynamicMain, the page contains a new link in the Regional Area. When you click the link, a new tab with the loaded task opens Taskflowid /WEB-INF/oracle/apps/financials/generalLedger/sharedSetup/ coaMappings/ui/flow/ CoaMappingsMainAreaFlow.xml#CoaMappingsMainAreaFlow This is the Taskflow path we retrieved from the Task Definition in FSM earlier in the process Table 1. Parameters and Values for the Task to be added to the customized Tasklist Figure 7. The parameters window of the newly added Task Access the FSM Task from the Journals Workarea Once the FSM task is added and its parameters defined, the user saves the record, closes the Composer making the new task immediately available to users with access to the Journals workarea (Refer to Figure 8 below). Figure 8. The COA Mapping Task is now visible and can be invoked from the Journals Workarea Additional Considerations If a Task Flow is part of a product that is deployed on the same app server as the Tasklist workarea then that task flow can be added to a customized tasklist in that workarea. Otherwise that task flow can be invoked from its parent product’s workarea tasklist by selecting that workarea from the Navigator menu. For Example The following Taskflows belong respectively to the Subledger Accounting, and to the General Ledger Products. /WEB-INF/oracle/apps/financials/subledgerAccounting/accountingMethodSetup/mappingSets/ui/flow/MappingSetFlow.xml#MappingSetFlow /WEB-INF/oracle/apps/financials/generalLedger/sharedSetup/coaMappings/ui/flow/CoaMappingsMainAreaFlow.xml#CoaMappingsMainAreaFlow Since both the Subledger Accounting and General Ledger products are part of the LedgerApp J2EE Applicaton and are both deployed on the General Ledger Cluster Server (Figure 8 below), the user can add both of the above taskflows to the tasklist in the /JournalEntryPage FocusVIewID Workarea. Note: both FSM Taskflows and Functional Taskflows can be added to the Tasklists as described in this document Figure 8. The Topology of the Fusion Financials Product Family. Note that SubLedger Accounting and General Ledger are both deployed on the Ledger App Conclusion In this document we have shown how an administrative user can edit the Tasklist in the Regional Area of a Fusion Apps page using Oracle Composer. This is useful for cases where tasks packaged in different workareas are frequently accessed by the same user. By making these tasks available from the same page, we minimize the number of steps in the navigation the user has to do to perform their transactions and queries in Fusion Apps. The example explained above showed that tasks classified as Setup tasks, meaning made accessible to implementation users from the FSM module can be added to the workarea of their respective Fusion application. This eliminates the need to navigate to FSM to access tasks that are both setup and regular maintenance tasks.

Prevent your Silverlight XAP file from caching in your browser.

- by mbcrump

If you work with Silverlight daily then you have run into this problem. Your XAP file has been cached in your browser and you have to empty your browser cache to resolve it. If your using Google Chrome then you typically do the following: Go to Options –> Clear Browsing History –> Empty the Cache and finally click Clear Browsing data. As you can see, this is a lot of unnecessary steps. It is even worse when you have a customer that says, “I can’t see the new features you just implemented!” and you realize it’s a cached xap problem. I have been struggling with a way to prevent my XAP file from caching inside of a browser for a while now and decided to implement the following solution. If the Visual Studio Debugger is attached then add a unique query string to the source param to force the XAP file to be refreshed. If the Visual Studio Debugger is not attached then add the source param as Visual Studio generates it. This is also in case I forget to remove the above code in my production environment. I want the ASP.NET code to be inline with my .ASPX page. (I do not want a separate code behind .cs page or .vb page attached to the .aspx page.) Below is an example of the hosting code generated when you create a new Silverlight project. As a quick refresher, the hard coded param name = “source” specifies the location of your XAP file. <form id="form1" runat="server" style="height:100%"> <div id="silverlightControlHost"> <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <param name="source" value="ClientBin/SilverlightApplication2.xap"/> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="4.0.50826.0" /> <param name="autoUpgrade" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50826.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div> </form> We are going to use a little bit of inline ASP.NET to generate the param name = source dynamically to prevent the XAP file from caching. Lets look at the completed solution: <form id="form1" runat="server" style="height:100%"> <div id="silverlightControlHost"> <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <% string strSourceFile = @"ClientBin/SilverlightApplication2.xap"; string param; if (System.Diagnostics.Debugger.IsAttached) //Debugger Attached - Refresh the XAP file. param = "<param name=\"source\" value=\"" + strSourceFile + "?" + DateTime.Now.Ticks + "\" />"; else { //Production Mode param = "<param name=\"source\" value=\"" + strSourceFile + "\" />"; } Response.Write(param); %> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="4.0.50826.0" /> <param name="autoUpgrade" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50826.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div> </form> We add the location to our XAP file to strSourceFile and if the debugger is attached then it will append DateTime.Now.Ticks to the XAP file source and force the browser to download the .XAP. If you view the page source of your Silverlight Application then you can verify it worked properly by looking at the param name = “source” tag as shown below. <param name="source" value="ClientBin/SilverlightApplication2.xap?634299001187160148" /> If the debugger is not attached then it will use the standard source tag as shown below. <param name="source" value="ClientBin/SilverlightApplication2.xap"/> At this point you may be asking, How do I prevent my XAP file from being cached on my production app? Well, you have two easy options: 1) I really don’t recommend this approach but you can force the XAP to be refreshed everytime with the following code snippet. <param name="source" value="ClientBin/SilverlightApplication2.xap?<%=Guid.NewGuid().ToString() %>"/> NOTE: You could also substitute the “Guid.NewGuid().ToString() for anything that create a random field. (I used DateTime.Now.Ticks earlier). 2) Another solution that I like even better involves checking the XAP Creation Date and appending it to the param name = source. This method was described by Lars Holm Jenson. <% string strSourceFile = @"ClientBin/SilverlightApplication2.xap"; string param; if (System.Diagnostics.Debugger.IsAttached) param = "<param name=\"source\" value=\"" + strSourceFile + "\" />"; else { string xappath = HttpContext.Current.Server.MapPath(@"") + @"\" + strSourceFile; DateTime xapCreationDate = System.IO.File.GetLastWriteTime(xappath); param = "<param name=\"source\" value=\"" + strSourceFile + "?ignore=" + xapCreationDate.ToString() + "\" />"; } Response.Write(param); %> As you can see, this problem has been solved. It will work with all web browsers and stubborn proxy servers that are caching your .XAP. If you enjoyed this article then check out my blog for others like this.

Before we get started with the Silverlight Controls, here is a couple of links to bookmark for the DevExpress Silverlight Controls: The Live Demos of the Silverlight Controls is located here. Great Video Tutorials of the Silverlight Controls are here. One thing that I liked about the DevExpress is how easy it was to find demos of each control. After you install the controls the following Program Group appears complete with “demos” that include full-source. So, the first question that you may ask is, “What is included?” Here is the official list below. I wanted to show several of the controls that I think developers will use the most. The Book – Very rich animation between switching pages. Very easy to add your own images and custom text. The Menu – This is another control that just looked great. You can easily add images to the menu items with a few lines of XAML. The Window / Dialog Box – You can use this control to make a very beautiful “Wizard” to help your users navigate between pages. This is useful in setup or installation. Calculator – This would be useful for any type of Banking app. Also a first that I’ve seen from a 3rd party Control company. DatePicker – This controls feels a lot smoother than the one provided by Microsoft. It also provides the ability to “Clear” the selection. Overall the DevExpress Silverlight Controls feature a lot of quality controls that you should check out. You can go ahead and download a trial version of it right now by clicking here. If you win the contest you can simply enter your registration key and continue using the product without reinstalling. Syncfusion User Interface Edition Before we get started with the Syncfusion User Interface Edition, here is a couple of links to bookmark. The Live Demos can be found here.

You may also download the documentation to your local machine if needed. Since the name of the package is “User Interface Edition”, I decided to share several samples that struck me as “awesome”. Dashboard Gauges – I was very impressed with the various gauges they have included. The digital clock also looks very impressive. Diagram – The diagrams are also very easy to build. In the sample project below you can drag/drop the shapes onto the content pane. More complex lines like the Bezier lines are also easy to create using Syncfusion. Scheduling – Another strong component was the Scheduling with built-in support for Themes. Tools – If all of that wasn’t enough, it also comes with a nice pack of essential tools. Syncfusion has a nice variety of Silverlight Controls that you should check out. You can go ahead and download a trial version of it right now by clicking here. Crypto Obfuscator The following feature set is what is important to me in an Obfuscator since I am a Silverlight/WP7 Developer: And thankfully this is what you get in Crypto Obfuscator. You can download a trial version right now if you want to go ahead and play with it. Let’s spend a few moments taking a look at the application. After you have installed Crypto Obfuscator you will see the following screen: After you click on Assemblies you have the option to add your .XAP file in: I went ahead and loaded my .xap file from a Silverlight Application. At this point, you can simply save your project and hit “Obfuscate” and your done. You don’t have to mess with any of the other settings if you don’t want too. Of course, you can change the settings and add obfuscation rules, watermarks and signing if you wish. After Obfuscation, it looks like this in .NET Reflector: I was trying to browse through methods and it actually crashed Reflector. This confirms the level of protection the obfuscator is providing. If this were a commercial application that my team built, I would have a huge smile on my face right now. Crypto Obfuscator is a great product and I hope you will spend the time learning more about it. Silverlight Spy Silverlight Spy is a runtime inspector tool that will tell you pretty much everything that is going on with the application. Basically, you give it a URL that contains a Silverlight application and you can explore the element tree, events, xaml and so much more. This has already been reviewed on MichaelCrump.net. _________________________________________________________________________________________ Thanks for reading and don’t forget to leave a comment below in order to win one of the four prizes available!

Premature-Optimization and Performance Anxiety

- by James Michael Hare

While writing my post analyzing the new .NET 4 ConcurrentDictionary class (here), I fell into one of the classic blunders that I myself always love to warn about. After analyzing the differences of time between a Dictionary with locking versus the new ConcurrentDictionary class, I noted that the ConcurrentDictionary was faster with read-heavy multi-threaded operations. Then, I made the classic blunder of thinking that because the original Dictionary with locking was faster for those write-heavy uses, it was the best choice for those types of tasks. In short, I fell into the premature-optimization anti-pattern. Basically, the premature-optimization anti-pattern is when a developer is coding very early for a perceived (whether rightly-or-wrongly) performance gain and sacrificing good design and maintainability in the process. At best, the performance gains are usually negligible and at worst, can either negatively impact performance, or can degrade maintainability so much that time to market suffers or the code becomes very fragile due to the complexity. Keep in mind the distinction above. I'm not talking about valid performance decisions. There are decisions one should make when designing and writing an application that are valid performance decisions. Examples of this are knowing the best data structures for a given situation (Dictionary versus List, for example) and choosing performance algorithms (linear search vs. binary search). But these in my mind are macro optimizations. The error is not in deciding to use a better data structure or algorithm, the anti-pattern as stated above is when you attempt to over-optimize early on in such a way that it sacrifices maintainability. In my case, I was actually considering trading the safety and maintainability gains of the ConcurrentDictionary (no locking required) for a slight performance gain by using the Dictionary with locking. This would have been a mistake as I would be trading maintainability (ConcurrentDictionary requires no locking which helps readability) and safety (ConcurrentDictionary is safe for iteration even while being modified and you don't risk the developer locking incorrectly) -- and I fell for it even when I knew to watch out for it. I think in my case, and it may be true for others as well, a large part of it was due to the time I was trained as a developer. I began college in in the 90s when C and C++ was king and hardware speed and memory were still relatively priceless commodities and not to be squandered. In those days, using a long instead of a short could waste precious resources, and as such, we were taught to try to minimize space and favor performance. This is why in many cases such early code-bases were very hard to maintain. I don't know how many times I heard back then to avoid too many function calls because of the overhead -- and in fact just last year I heard a new hire in the company where I work declare that she didn't want to refactor a long method because of function call overhead. Now back then, that may have been a valid concern, but with today's modern hardware even if you're calling a trivial method in an extremely tight loop (which chances are the JIT compiler would optimize anyway) the results of removing method calls to speed up performance are negligible for the great majority of applications. Now, obviously, there are those coding applications where speed is absolutely king (for example drivers, computer games, operating systems) where such sacrifices may be made. But I would strongly advice against such optimization because of it's cost. Many folks that are performing an optimization think it's always a win-win. That they're simply adding speed to the application, what could possibly be wrong with that? What they don't realize is the cost of their choice. For every piece of straight-forward code that you obfuscate with performance enhancements, you risk the introduction of bugs in the long term technical debt of the application. It will become so fragile over time that maintenance will become a nightmare. I've seen such applications in places I have worked. There are times I've seen applications where the designer was so obsessed with performance that they even designed their own memory management system for their application to try to squeeze out every ounce of performance. Unfortunately, the application stability often suffers as a result and it is very difficult for anyone other than the original designer to maintain. I've even seen this recently where I heard a C++ developer bemoaning that in VS2010 the iterators are about twice as slow as they used to be because Microsoft added range checking (probably as part of the 0x standard implementation). To me this was almost a joke. Twice as slow sounds bad, but it almost never as bad as you think -- especially if you're gaining safety. The only time twice is really that much slower is when once was too slow to begin with. Think about it. 2 minutes is slow as a response time because 1 minute is slow. But if an iterator takes 1 microsecond to move one position and a new, safer iterator takes 2 microseconds, this is trivial! The only way you'd ever really notice this would be in iterating a collection just for the sake of iterating (i.e. no other operations). To my mind, the added safety makes the extra time worth it. Always favor safety and maintainability when you can. I know it can be a hard habit to break, especially if you started out your career early or in a language such as C where they are very performance conscious. But in reality, these type of micro-optimizations only end up hurting you in the long run. Remember the two laws of optimization. I'm not sure where I first heard these, but they are so true: For beginners: Do not optimize. For experts: Do not optimize yet. This is so true. If you're a beginner, resist the urge to optimize at all costs. And if you are an expert, delay that decision. As long as you have chosen the right data structures and algorithms for your task, your performance will probably be more than sufficient. Chances are it will be network, database, or disk hits that will be your slow-down, not your code. As they say, 98% of your code's bottleneck is in 2% of your code so premature-optimization may add maintenance and safety debt that won't have any measurable impact. Instead, code for maintainability and safety, and then, and only then, when you find a true bottleneck, then you should go back and optimize further.

Using Sitecore RenderingContext Parameters as MVC controller action arguments

- by Kyle Burns

I have been working with the Technical Preview of Sitecore 6.6 on a project and have been for the most part happy with the way that Sitecore (which truly is an MVC implementation unto itself) has been expanded to support ASP.NET MVC. That said, getting up to speed with the combined platform has not been entirely without stumbles and today I want to share one area where Sitecore could have really made things shine from the "it just works" perspective. A couple days ago I was asked by a colleague about the usage of the "Parameters" field that is defined on Sitecore's Controller Rendering data template. Based on the standard way that Sitecore handles a field named Parameters, I was able to deduce that the field expected key/value pairs separated by the "&" character, but beyond that I wasn't sure and didn't see anything from a documentation perspective to guide me, so it was time to dig and find out where the data in the field was made available. My first thought was that it would be really nice if Sitecore handled the parameters in this field consistently with the way that ASP.NET MVC handles the various parameter collections on the HttpRequest object and automatically maps them to parameters of the action method executing. Being the hopeful sort, I configured a name/value pair on one of my renderings, added a parameter with matching name to the controller action and fired up the bugger to see... that the parameter was not populated. Having established that the field's value was not going to be presented to me the way that I had hoped it would, the next assumption that I would work on was that Sitecore would handle this field similar to how they handle other similar data and would plug it into some ambient object that I could reference from within the controller method. After a considerable amount of guessing, testing, and cracking code open with Redgate's Reflector (a must-have companion to Sitecore documentation), I found that the most direct way to access the parameter was through the ambient RenderingContext object using code similar to: string myArgument = string.Empty; var rc = Sitecore.Mvc.Presentation.RenderingContext.CurrentOrNull; if (rc != null) { var parms = rc.Rendering.Parameters; myArgument = parms["myArgument"]; } At this point, we know how this field is used out of the box from Sitecore and can provide information from Sitecore's Content Editor that will be available when the controller action is executing, but it feels a little dirty. In order to properly test the action method I would have to do a lot of setup work and possible use an isolation framework such as Pex and Moles to get at a value that my action method is dependent upon. Notice I said that my method is dependent upon the value but in order to meet that dependency I've accepted another dependency upon Sitecore's RenderingContext. I'm a big believer in, when possible, ensuring that any piece of code explicitly advertises dependencies using the method signature, so I found myself still wanting this to work the same as if the parameters were in the request route, querystring, or form by being able to add a myArgument parameter to the action method and have this parameter populated by the framework. Lucky for us, the ASP.NET MVC framework is extremely flexible and provides some easy to grok and use extensibility points. ASP.NET MVC is able to provide information from the request as input parameters to controller actions because it uses objects which implement an interface called IValueProvider and have been registered to service the application. The most basic statement of responsibility for an IValueProvider implementation is "I know about some data which is indexed by key. If you hand me the key for a piece of data that I know about I give you that data". When preparing to invoke a controller action, the framework queries registered IValueProvider implementations with the name of each method argument to see if the ValueProvider can supply a value for the parameter. (the rest of this post will assume you're working along and make a lot more sense if you do) Let's pull Sitecore out of the equation for a second to simplify things and create an extremely simple IValueProvider implementation. For this example, I first create a new ASP.NET MVC3 project in Visual Studio, selecting "Internet Application" and otherwise taking defaults (I'm assuming that anyone reading this far in the post either already knows how to do this or will need to take a quick run through one of the many available basic MVC tutorials such as the MVC Music Store). Once the new project is created, go to the Index action of HomeController. This action sets a Message property on the ViewBag to "Welcome to ASP.NET MVC!" and invokes the View, which has been coded to display the Message. For our example, we will remove the hard coded message from this controller (although we'll leave it just as hard coded somewhere else - this is sample code). For the first step in our exercise, add a string parameter to the Index action method called welcomeMessage and use the value of this argument to set the ViewBag.Message property. The updated Index action should look like: public ActionResult Index(string welcomeMessage) { ViewBag.Message = welcomeMessage; return View(); } This represents the entirety of the change that you will make to either the controller or view. If you run the application now, the home page will display and no message will be presented to the user because no value was supplied to the Action method. Let's now write a ValueProvider to ensure this parameter gets populated. We'll start by creating a new class called StaticValueProvider. When the class is created, we'll update the using statements to ensure that they include the following: using System.Collections.Specialized; using System.Globalization; using System.Web.Mvc; With the appropriate using statements in place, we'll update the StaticValueProvider class to implement the IValueProvider interface. The System.Web.Mvc library already contains a pretty flexible dictionary-like implementation called NameValueCollectionValueProvider, so we'll just wrap that and let it do most of the real work for us. The completed class looks like: public class StaticValueProvider : IValueProvider { private NameValueCollectionValueProvider _wrappedProvider; public StaticValueProvider(ControllerContext controllerContext) { var parameters = new NameValueCollection(); parameters.Add("welcomeMessage", "Hello from the value provider!"); _wrappedProvider = new NameValueCollectionValueProvider(parameters, CultureInfo.InvariantCulture); } public bool ContainsPrefix(string prefix) { return _wrappedProvider.ContainsPrefix(prefix); } public ValueProviderResult GetValue(string key) { return _wrappedProvider.GetValue(key); } } Notice that the only entry in the collection matches the name of the argument to our HomeController's Index action. This is the important "secret sauce" that will make things work. We've got our new value provider now, but that's not quite enough to be finished. Mvc obtains IValueProvider instances using factories that are registered when the application starts up. These factories extend the abstract ValueProviderFactory class by initializing and returning the appropriate implementation of IValueProvider from the GetValueProvider method. While I wouldn't do so in production code, for the sake of this example, I'm going to add the following class definition within the StaticValueProvider.cs source file: public class StaticValueProviderFactory : ValueProviderFactory { public override IValueProvider GetValueProvider(ControllerContext controllerContext) { return new StaticValueProvider(controllerContext); } } Now that we have a factory, we can register it by adding the following line to the end of the Application_Start method in Global.asax.cs: ValueProviderFactories.Factories.Add(new StaticValueProviderFactory()); If you've done everything right to this point, you should be able to run the application and be presented with the home page reading "Hello from the value provider!". Now that you have the basics of the IValueProvider down, you have everything you need to enhance your Sitecore MVC implementation by adding an IValueProvider that exposes values from the ambient RenderingContext's Parameters property. I'll provide the code for the IValueProvider implementation (which should look VERY familiar) and you can use the work we've already done as a reference to create and register the factory: public class RenderingContextValueProvider : IValueProvider { private NameValueCollectionValueProvider _wrappedProvider = null; public RenderingContextValueProvider(ControllerContext controllerContext) { var collection = new NameValueCollection(); var rc = RenderingContext.CurrentOrNull; if (rc != null && rc.Rendering != null) { foreach(var parameter in rc.Rendering.Parameters) { collection.Add(parameter.Key, parameter.Value); } } _wrappedProvider = new NameValueCollectionValueProvider(collection, CultureInfo.InvariantCulture); } public bool ContainsPrefix(string prefix) { return _wrappedProvider.ContainsPrefix(prefix); } public ValueProviderResult GetValue(string key) { return _wrappedProvider.GetValue(key); } } In this post I've discussed the MVC IValueProvider used to map data to controller action method arguments and how this can be integrated into your Sitecore 6.6 MVC solution.

How accurate is "Business logic should be in a service, not in a model"?

- by Jeroen Vannevel

Situation Earlier this evening I gave an answer to a question on StackOverflow. The question: Editing of an existing object should be done in repository layer or in service? For example if I have a User that has debt. I want to change his debt. Should I do it in UserRepository or in service for example BuyingService by getting an object, editing it and saving it ? My answer: You should leave the responsibility of mutating an object to that same object and use the repository to retrieve this object. Example situation: class User { private int debt; // debt in cents private string name; // getters public void makePayment(int cents){ debt -= cents; } } class UserRepository { public User GetUserByName(string name){ // Get appropriate user from database } } A comment I received: Business logic should really be in a service. Not in a model. What does the internet say? So, this got me searching since I've never really (consciously) used a service layer. I started reading up on the Service Layer pattern and the Unit Of Work pattern but so far I can't say I'm convinced a service layer has to be used. Take for example this article by Martin Fowler on the anti-pattern of an Anemic Domain Model: There are objects, many named after the nouns in the domain space, and these objects are connected with the rich relationships and structure that true domain models have. The catch comes when you look at the behavior, and you realize that there is hardly any behavior on these objects, making them little more than bags of getters and setters. Indeed often these models come with design rules that say that you are not to put any domain logic in the the domain objects. Instead there are a set of service objects which capture all the domain logic. These services live on top of the domain model and use the domain model for data. (...) The logic that should be in a domain object is domain logic - validations, calculations, business rules - whatever you like to call it. To me, this seemed exactly what the situation was about: I advocated the manipulation of an object's data by introducing methods inside that class that do just that. However I realize that this should be a given either way, and it probably has more to do with how these methods are invoked (using a repository). I also had the feeling that in that article (see below), a Service Layer is more considered as a façade that delegates work to the underlying model, than an actual work-intensive layer. Application Layer [his name for Service Layer]: Defines the jobs the software is supposed to do and directs the expressive domain objects to work out problems. The tasks this layer is responsible for are meaningful to the business or necessary for interaction with the application layers of other systems. This layer is kept thin. It does not contain business rules or knowledge, but only coordinates tasks and delegates work to collaborations of domain objects in the next layer down. It does not have state reflecting the business situation, but it can have state that reflects the progress of a task for the user or the program. Which is reinforced here: Service interfaces. Services expose a service interface to which all inbound messages are sent. You can think of a service interface as a façade that exposes the business logic implemented in the application (typically, logic in the business layer) to potential consumers. And here: The service layer should be devoid of any application or business logic and should focus primarily on a few concerns. It should wrap Business Layer calls, translate your Domain in a common language that your clients can understand, and handle the communication medium between server and requesting client. This is a serious contrast to other resources that talk about the Service Layer: The service layer should consist of classes with methods that are units of work with actions that belong in the same transaction. Or the second answer to a question I've already linked: At some point, your application will want some business logic. Also, you might want to validate the input to make sure that there isn't something evil or nonperforming being requested. This logic belongs in your service layer. "Solution"? Following the guidelines in this answer, I came up with the following approach that uses a Service Layer: class UserController : Controller { private UserService _userService; public UserController(UserService userService){ _userService = userService; } public ActionResult MakeHimPay(string username, int amount) { _userService.MakeHimPay(username, amount); return RedirectToAction("ShowUserOverview"); } public ActionResult ShowUserOverview() { return View(); } } class UserService { private IUserRepository _userRepository; public UserService(IUserRepository userRepository) { _userRepository = userRepository; } public void MakeHimPay(username, amount) { _userRepository.GetUserByName(username).makePayment(amount); } } class UserRepository { public User GetUserByName(string name){ // Get appropriate user from database } } class User { private int debt; // debt in cents private string name; // getters public void makePayment(int cents){ debt -= cents; } } Conclusion All together not much has changed here: code from the controller has moved to the service layer (which is a good thing, so there is an upside to this approach). However this doesn't look like it had anything to do with my original answer. I realize design patterns are guidelines, not rules set in stone to be implemented whenever possible. Yet I have not found a definitive explanation of the service layer and how it should be regarded. Is it a means to simply extract logic from the controller and put it inside a service instead? Is it supposed to form a contract between the controller and the domain? Should there be a layer between the domain and the service layer? And, last but not least: following the original comment Business logic should really be in a service. Not in a model. Is this correct? How would I introduce my business logic in a service instead of the model?

ASP.NET WebAPI Security 3: Extensible Authentication Framework

- by Your DisplayName here!

In my last post, I described the identity architecture of ASP.NET Web API. The short version was, that Web API (beta 1) does not really have an authentication system on its own, but inherits the client security context from its host. This is fine in many situations (e.g. AJAX style callbacks with an already established logon session). But there are many cases where you don’t use the containing web application for authentication, but need to do it yourself. Examples of that would be token based authentication and clients that don’t run in the context of the web application (e.g. desktop clients / mobile). Since Web API provides a nice extensibility model, it is easy to implement whatever security framework you want on top of it. My design goals were: Easy to use. Extensible. Claims-based. ..and of course, this should always behave the same, regardless of the hosting environment. In the rest of the post I am outlining some of the bits and pieces, So you know what you are dealing with, in case you want to try the code. At the very heart… is a so called message handler. This is a Web API extensibility point that gets to see (and modify if needed) all incoming and outgoing requests. Handlers run after the conversion from host to Web API, which means that handler code deals with HttpRequestMessage and HttpResponseMessage. See Pedro’s post for more information on the processing pipeline. This handler requires a configuration object for initialization. Currently this is very simple, it contains: Settings for the various authentication and credential types Settings for claims transformation Ability to block identity inheritance from host The most important part here is the credential type support, but I will come back to that later. The logic of the message handler is simple: Look at the incoming request. If the request contains an authorization header, try to authenticate the client. If this is successful, create a claims principal and populate the usual places. If not, return a 401 status code and set the Www-Authenticate header. Look at outgoing response, if the status code is 401, set the Www-Authenticate header. Credential type support Under the covers I use the WIF security token handler infrastructure to validate credentials and to turn security tokens into claims. The idea is simple: an authorization header consists of two pieces: the schema and the actual “token”. My configuration object allows to associate a security token handler with a scheme. This way you only need to implement support for a specific credential type, and map that to the incoming scheme value. The current version supports HTTP Basic Authentication as well as SAML and SWT tokens. (I needed to do some surgery on the standard security token handlers, since WIF does not directly support string-ified tokens. The next version of .NET will fix that, and the code should become simpler then). You can e.g. use this code to hook up a username/password handler to the Basic scheme (the default scheme name for Basic Authentication). config.Handler.AddBasicAuthenticationHandler( (username, password) => username == password); You simply have to provide a password validation function which could of course point back to your existing password library or e.g. membership. The following code maps a token handler for Simple Web Tokens (SWT) to the Bearer scheme (the currently favoured scheme name for OAuth2). You simply have to specify the issuer name, realm and shared signature key: config.Handler.AddSimpleWebTokenHandler( "Bearer", http://identity.thinktecture.com/trust, Constants.Realm, "Dc9Mpi3jaaaUpBQpa/4R7XtUsa3D/ALSjTVvK8IUZbg="); For certain integration scenarios it is very useful if your Web API can consume SAML tokens. This is also easily accomplishable. The following code uses the standard WIF API to configure the usual SAMLisms like issuer, audience, service certificate and certificate validation. Both SAML 1.1 and 2.0 are supported. var registry = new ConfigurationBasedIssuerNameRegistry(); registry.AddTrustedIssuer( "d1 c5 b1 25 97 d0 36 94 65 1c e2 64 fe 48 06 01 35 f7 bd db", "ADFS"); var adfsConfig = new SecurityTokenHandlerConfiguration(); adfsConfig.AudienceRestriction.AllowedAudienceUris.Add( new Uri(Constants.Realm)); adfsConfig.IssuerNameRegistry = registry; adfsConfig.CertificateValidator = X509CertificateValidator.None; // token decryption (read from configuration section) adfsConfig.ServiceTokenResolver = FederatedAuthentication.ServiceConfiguration.CreateAggregateTokenResolver(); config.Handler.AddSaml11SecurityTokenHandler("SAML", adfsConfig); Claims Transformation After successful authentication, if configured, the standard WIF ClaimsAuthenticationManager is called to run claims transformation and validation logic. This stage is used to transform the “technical” claims from the security token into application claims. You can either have a separate transformation logic, or share on e.g. with the containing web application. That’s just a matter of configuration. Adding the authentication handler to a Web API application In the spirit of Web API this is done in code, e.g. global.asax for web hosting: protected void Application_Start() { AreaRegistration.RegisterAllAreas(); ConfigureApis(GlobalConfiguration.Configuration); RegisterGlobalFilters(GlobalFilters.Filters); RegisterRoutes(RouteTable.Routes); BundleTable.Bundles.RegisterTemplateBundles(); } private void ConfigureApis(HttpConfiguration configuration) { configuration.MessageHandlers.Add( new AuthenticationHandler(ConfigureAuthentication())); } private AuthenticationConfiguration ConfigureAuthentication() { var config = new AuthenticationConfiguration { // sample claims transformation for consultants sample, comment out to see raw claims ClaimsAuthenticationManager = new ApiClaimsTransformer(), // value of the www-authenticate header, // if not set, the first scheme added to the handler collection is used DefaultAuthenticationScheme = "Basic" }; // add token handlers - see above return config; } You can find the full source code and some samples here. In the next post I will describe some of the samples in the download, and then move on to authorization. HTH
