• Tellago releases a RESTful API for BizTalk Server business rules

  - by Charles Young

  Jesus Rodriguez has blogged recently on Tellago Devlabs' release of an open source RESTful API for BizTalk Server Business Rules.   This is an excellent addition to the BizTalk ecosystem and I congratulate Tellago on their work.   See http://weblogs.asp.net/gsusx/archive/2011/02/08/tellago-devlabs-a-restful-api-for-biztalk-server-business-rules.aspx   The Microsoft BRE was originally designed to be used as an embedded library in .NET applications. This is reflected in the implementation of the Rules Engine Update (REU) Service which is a TCP/IP service that is hosted by a Windows service running locally on each BizTalk box. The job of the REU is to distribute rules, managed and held in a central database repository, across the various servers in a BizTalk group.   The engine is therefore distributed on each box, rather than exploited behind a central rules service.   This model is all very well, but proves quite restrictive in enterprise environments. The problem is that the BRE can only run legally on licensed BizTalk boxes. Increasingly we need to deliver rules capabilities across a more widely distributed environment. For example, in the project I am working on currently, we need to surface decisioning capabilities for use within WF workflow services running under AppFabric on non-BTS boxes. The BRE does not, currently, offer any centralised rule service facilities out of the box, and hence you have to roll your own (and then run your rules services on BTS boxes which has raised a few eyebrows on my current project, as all other WCF services run on a dedicated server farm ).   Tellago's API addresses this by providing a RESTful API for querying the rules repository and executing rule sets against XML passed in the request payload. As Jesus points out in his post, using a RESTful approach hugely increases the reach of BRE-based decisioning, allowing simple invocation from code written in dynamic languages, mobile devices, etc.   We developed our own SOAP-based general-purpose rules service to handle scenarios such as the one we face on my current project. SOAP is arguably better suited to enterprise service bus environments (please don't 'flame' me - I refuse to engage in the RESTFul vs. SOAP war). For example, on my current project we use claims based authorisation across the entire service bus and use WIF and WS-Federation for this purpose.   We have extended this to the rules service. I can't release the code for commercial reasons :-( but this approach allows us to legally extend the reach of BRE far beyond the confines of the BizTalk boxes on which it runs and to provide general purpose decisioning capabilities on the bus.   So, well done Tellago.   I haven't had a chance to play with the API yet, but am looking forward to doing so.

• Hello From South Florida

  - by Sam Abraham

  Fellow Blog Readers: I figured I use my first blog post on GeeksWithBlogs to introduce myself.   I recently relocated from Long Island, NY to South Florida where I joined a local company as Software Engineer specializing in technologies such as C#, ASP.Net 3.5, WCF, Silverlight, SQL Server 2008 and LINQ, to name a few. I am an MCP and MCTS ASP.Net 3.5, looking to get my .Net 4.0 certification soon.   Having been in industry for a few years so far, I figured I would share with you my take on the importance of being involved(at least attending) in local user groups.   I am a firm believer that besides using a certain technology, the best way to expand one’s knowledge is by sharing it with others and being equally open to learn from others just as much as you are willing to share what you know.   In my opinion, an important factor that makes a good developer stand-out is his/her ability to keep abreast with the latest and greatest even in areas outside his/her direct expertise.   Additionally, having spoken to various recruiters, technical user group attendees are always favorably looked upon as genuinely interested in their field and willing to take the initiative to expand their knowledge which offers job candidates good leverage when competing for jobs.   I believe I am very blessed to be in an area with a very strong and vibrant developer community. I found in the local .Net community leadership a genuine interest in constantly extending the opportunity to all developers to get more involved and encouraging those who are willing to take that initiative achieve their goal: Speak in meetings, volunteer at events or write and publish articles/blogs about latest and greatest technologies.   With Vishal Shukla (Site director for the West Palm Beach .Net User Group) traveling overseas, I have been extended the opportunity to come on board as site coordinator for FladotNet's WPB .Net User Group along with Venkata Subramanian, an opportunity which I gratefully accepted.   Being involved in running a .Net User Group will surely help me personally and professionally, but my real hope is to use this opportunity to assist in delivering the ultimate common-goal: spread the word about new .Net Technologies, help everybody get more involved and simply have fun learning new things.   With my introduction out of the way, in the next few days I will be posting some notes on an upcoming talk I will be giving about MVC2 and VS2010 in mid-April.   Environment.Exit(0); --Sam

• Why I Love Microsoft Development

  - by Brian Lanham

  I've been writing software for a while and recently had an opportunity to broaden my horizons and start developing for iOS. We decided to leverage, as much as possible, our existing skills and use MonoTouch and MonoDevelop by Novell.    For those of you who do not know, Mono is a .NET port originally designed for Linux but adapted for other platforms as well. MonoTouch is a port specifically for building iOS applications using the .NET framework. MonoDroid is a port (in CTP-esque release) for Android.   A MISSING COMPONENT - VISUAL DESIGNER   MonoDevelop lacks one very significant component compared with other tools I am using: NO VISUAL DESIGNER. Instead of using an integrated visual designer, MonoDevelop shells to the Mac OS "Interface Builder".  Since MonoDevelop lets me have a "Visual Studio-esque" feel *and* I get to use C#, AND it's FREE, I am gladly willing to overlook this.  In fact, it's not even a question.  Free?  Sure, I'll take it with no Visual Designer.   In my experiences I've grown from UNIX and DOS to .NET development through many steps. Java/JSP/Servlets; Windows; Web; etc. I've been doing .NET for quite a few years and I guess I just got "comfortable" with the tools.   WHY AM I NOT GETTING IT?   Interface Builder (IB) is amazingly confusing for me. I had the opportunity to speak at the Northern VA Code Camp on 12/11/2010. My presentation was "Getting Started with iOS Development using MonoTouch and C#".    At the visual design part of the presentation, I asked one of the 3 or 4 Mac developers in the room about my confusion with the IB. I don't understand why the "Classes" list includes objects. I don't understand what "File's Owner" is. And, most importantly, WHAT THE HECK IS AN OUTLET AND WHY IS IT NECESSARY?!?!?"   His response to these question (especially Outlets): "They did it wrong."   I'm accustom to a visual designer that creates variables for graphical widgets for me. Not IB. Instead, I have to create "Outlets" manually. I still do not understand why and, the explanation from a seasoned Mac developer is that it's wrong. (He received nods of confirmation from the other Mac devs in the room.)   I LOVE MS DEV   I love development for Microsoft platforms using Microsoft development tools. I love Windows 7. I love Visual Studio 2010. I love SQL Server. Azure, Entity Framework, Active Directory, Office, WCF/WF/WPF, etc. are all designed with integration in mind. They are also all designed with developers in mind.   Steve Ballmer recently ranted "It's the developers!" That's why it is relatively quick to build apps using MS tools. Clearly, MS knows that while we usually enjoy building technology solutions, we are here to make money. And we need tools that accelerate our time to market without compromising the power and quality of our solutions.   So, yeah, I am sucking up I guess. But I love Microsoft Development. Thank you, Microsoft, for providing the plethora of great development tools.    P.S. (but please slow down a bit…I'm having trouble keeping up!)

• Content Based Routing with BRE and ESB

  - by Christopher House

  I've been working with BizTalk 2009 and the ESB toolkit for the past couple of days.  This is actually my first exposure to ESB and so far I'm pleased with how easy it is to work with. Initially we had planned to use UDDI for storing endpoint information.  However after discussing this with my client, we opted to look at BRE instead of UDDI since we're already storing transforms in BRE.  Fortunately making the change to BRE from UDDI was quite simple.  This solution of course has the added advantage of not needing to go through the convoluted process of registering our endpoints in UDDI. The first thing to remember if you want to do content based routing with BRE and ESB is that the pipleines included in the ESB toolkit don't include disassembler components.  This means that you'll need to first create a custom recieve pipeline with the necessary disassembler for your message type as well as the ESB components, itinerary selector and dispather. Next you need to create a BRE policy.  The ESB.ContextInfo vocabulary contains vocabulary links for the various items in the ESB context dictionary.  In this vocabulary, you'll find an item called Context Message Type, use this as the left hand side of your condition.  Set the right hand side to your message type, something like http://your.message.namespace/#yourrootelement.  Now find the ESB.EndPointInfo vocabulary.  This contains links to all the properties related to endpoint information.  Use the various set operators in your rule's action to configure your endpoint. In the example above, I'm using the WCF-SQL adapter. Now that the hard work is out of the way, you just need to configure the resolver in your itinerary. Nothing complicated here.  Just select BRE as your resolver implementation and select your policy from the drop-down list.  Note that when you select a policy, the Version field will be automatically filled in with the version of your policy.  If you leave this as-is, the resolver will always use that policy version.  Alternatively, you can clear the version number and the resolver will use the highest deployed version.

• Telesharp – An Application Repository for .NET applications

  - by cibrax

  A year ago, we released SO-Aware as our first product in Tellago Studios. SO-Aware represented a new way to manage web services and all the related artifacts like configuration, tests or monitoring data in the Microsoft stack. It was based on the idea of using a lightweight SOA governance approach with a central repository exposed through RESTful services. At that point, we thought the same idea could be extended to enterprise applications in general by providing a generic repository for many of the runtime or design time artifacts generated during the development like configuration, application description or topology (a high level view of the components that made up a system), logging information or binaries. It took us several months to give a form to that idea and implement it as a product, but it is finally here and I am very proud to announce the release today under the name of “TeleSharp”. Telesharp provides in a nutshell the following features, 1. Configure your application topology in a central repository. Application topology in this context means that you can decompose your application and describe it in terms of components and how they interact each other. For example, you can tell that the CRM system is made up of a couple of WCF services and a ASP.NET MVC front end. 2. Centralize configuration for your applications and components.  You can import existing .NET configuration sections into the repository and associate them to the different components. In addition, environment overrides are supported for the configuration sections. We provide tooling and extensions in Visual Studio for managing all the configuration, and a set of powershell commands for automating the configuration deployment. 3. Browse all the assemblies and types remotely in your application servers in a web browser using an interface similar to any of the existing .NET reflection tools. You can easily determine this way whether the server is running the correct version of your applications. 4. Centralize logging and exception management into the repository. You get different reports and a pivot viewer experience for browsing all the different logging information generated by your applications. In addition, TeleSharp provides different providers for pushing the logging information to the central repository using well-known frameworks like ELMAH, Log4Net, EntLib or even Windows ETW.  The central repository itself is implemented as a set of OData services that any application can easily consume using regular Http. You can read more details in this introductory post If you think this product can be a good fit in your organization, you can request a trial version in our Tellago Studios website.

• Web Apps vs Web Services: 302s and 401s are not always good Friends

  - by Your DisplayName here!

  It is not very uncommon to have web sites that have web UX and services content. The UX part maybe uses WS-Federation (or some other redirect based mechanism). That means whenever an authorization error occurs (401 status code), this is picked by the corresponding redirect module and turned into a redirect (302) to the login page. All is good. But in services, when you emit a 401, you typically want that status code to travel back to the client agent, so it can do error handling. These two approaches conflict. If you think (like me) that you should separate UX and services into separate apps, you don’t need to read on. Just do it ;) If you need to mix both mechanisms in a single app – here’s how I solved it for a project. I sub classed the redirect module – this was in my case the WIF WS-Federation HTTP module and modified the OnAuthorizationFailed method. In there I check for a special HttpContext item, and if that is present, I suppress the redirect. Otherwise everything works as normal: class ServiceAwareWSFederationAuthenticationModule : WSFederationAuthenticationModule {     protected override void OnAuthorizationFailed(AuthorizationFailedEventArgs e)     {         base.OnAuthorizationFailed(e);         var isService = HttpContext.Current.Items[AdvertiseWcfInHttpPipelineBehavior.DefaultLabel];         if (isService != null)         {             e.RedirectToIdentityProvider = false;         }     } } Now the question is, how do you smuggle that value into the HttpContext. If it is a MVC based web service, that’s easy of course. In the case of WCF, one approach that worked for me was to set it in a service behavior (dispatch message inspector to be exact): public void BeforeSendReply( ref Message reply, object correlationState) {     if (HttpContext.Current != null)     {         HttpContext.Current.Items[DefaultLabel] = true;     } } HTH

• What layer to introduce human readable error messages?

  - by MrLane

  One of the things that I have never been happy with on any project I have worked on over the years and have really not been able to resolve myself is exactly at what tier in an application should human readable error information be retrieved for display to a user. A common approach that has worked well has been to return strongly typed/concrete "result objects" from the methods on the public surface of the business tier/API. A method on the interface may be: public ClearUserAccountsResult ClearUserAccounts(ClearUserAccountsParam param); And the result class implementation: public class ClearUserAccountsResult : IResult { public readonly List<Account> ClearedAccounts{get; set;} public readonly bool Success {get; set;} // Implements IResult public readonly string Message{get; set;} // Implements IResult, human readable // Constructor implemented here to set readonly properties... } This works great when the API needs to be exposed over WCF as the result object can be serialized. Again this is only done on the public surface of the API/business tier. The error message can also be looked up from the database, which means it can be changed and localized. However, it has always been suspect to me, this idea of returning human readable information from the business tier like this, partly because what constitutes the public surface of the API may change over time...and it may be the case that the API will need to be reused by other API components in the future that do not need the human readable string messages (and looking them up from a database would be an expensive waste). I am thinking a better approach is to keep the business objects free from such result objects and keep them simple and then retrieve human readable error strings somewhere closer to the UI layer or only in the UI itself, but I have two problems here: 1) The UI may be a remote client (Winforms/WPF/Silverlight) or an ASP.NET web application hosted on another server. In these cases the UI will have to fetch the error strings from the server. 2) Often there are multiple legitimate modes of failure. If the business tier becomes so vague and generic in the way it returns errors there may not be enough information exposed publicly to tell what the error actually was: i.e: if a method has 3 modes of legitimate failure but returns a boolean to indicate failure, you cannot work out what the appropriate message to display to the user should be. I have thought about using failure enums as a substitute, they can indicate a specific error that can be tested for and coded against. This is sometimes useful within the business tier itself as a way of passing via method returns the specifics of a failure rather than just a boolean, but it is not so good for serialization scenarios. Is there a well worn pattern for this? What do people think? Thanks.

• OData &ndash; The easiest service I can create

  - by Jon Dalberg

  I wanted to create an OData service with the least amount of code so I fired up Visual Studio and got cracking. I decided to serve up a list of naughty words and make them read-only. Create a new web project. I created an empty MVC 2 application but MVC is not required for OData. Add a new WCF Data Service to the project. I named mine NastyWords.svc since I’m serving up a list of nasty words. Add a class to expose via the service: NastyWord 1: [DataServiceKey("Word")] 2: public class NastyWord 3: { 4: public string Word { get; set; } 5: }   I need to be able to uniquely identify instances of NastyWords for the DataService so I used the DataServiceKey attribute with the “Word” property as the key. I could have added an “ID” property which would have uniquely identified them and would then not need the “DataServiceKey” attribute because the DataService would apply some reflection and heuristics to guess at which property would be the unique identifier. However, the words themselves are unique so adding an “ID” property would be redundantly repetitive. Then I created a data source to expose my NastyWord objects to the service. This is just a simple class with IQueryable<T> properties exposing the entities for my service: 1: public class NastyWordsDataSource 2: { 3: private static IList<NastyWord> words = new List<NastyWord> 4: { 5: new NastyWord{ Word="crap"}, 6: new NastyWord{ Word="darn"}, 7: new NastyWord{ Word="hell"}, 8: new NastyWord{ Word="shucks"} 9: }; 10:   11: public NastyWordsDataSource() 12: { 13: NastyWords = words.AsQueryable(); 14: } 15:   16: public IQueryable<NastyWord> NastyWords { get; private set; } 17: }   Now I can go to the NastyWords.svc class and tell it which data source to use and which entities to expose: 1: public class NastyWords : DataService<NastyWordsDataSource> 2: { 3: // This method is called only once to initialize service-wide policies. 4: public static void InitializeService(DataServiceConfiguration config) 5: { 6: config.SetEntitySetAccessRule("*", EntitySetRights.AllRead); 7: config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; 8: } 9: }   Compile and browse to my NastWords.svc and weep with joy Now I can query my service just like any other OData service. Next time, I’ll modify this service to allow updates to sent so I can build up my list of nasty words. Enjoy!

• How granular should a command be in a CQ[R]S model?

  - by Aaronaught

  I'm considering a project to migrate part of our WCF-based SOA over to a service bus model (probably nServiceBus) and using some basic pub-sub to achieve Command-Query Separation. I'm not new to SOA, or even to service bus models, but I confess that until recently my concept of "separation" was limited to run-of-the-mill database mirroring and replication. Still, I'm attracted to the idea because it seems to provide all the benefits of an eventually-consistent system while sidestepping many of the obvious drawbacks (most notably the lack of proper transactional support). I've read a lot on the subject from Udi Dahan who is basically the guru on ESB architectures (at least in the Microsoft world), but one thing he says really puzzles me: As we get larger entities with more fields on them, we also get more actors working with those same entities, and the higher the likelihood that something will touch some attribute of them at any given time, increasing the number of concurrency conflicts. [...] A core element of CQRS is rethinking the design of the user interface to enable us to capture our users’ intent such that making a customer preferred is a different unit of work for the user than indicating that the customer has moved or that they’ve gotten married. Using an Excel-like UI for data changes doesn’t capture intent, as we saw above. -- Udi Dahan, Clarified CQRS From the perspective described in the quotation, it's hard to argue with that logic. But it seems to go against the grain with respect to SOAs. An SOA (and really services in general) are supposed to deal with coarse-grained messages so as to minimize network chatter - among many other benefits. I realize that network chatter is less of an issue when you've got highly-distributed systems with good message queuing and none of the baggage of RPC, but it doesn't seem wise to dismiss the issue entirely. Udi almost seems to be saying that every attribute change (i.e. field update) ought to be its own command, which is hard to imagine in the context of one user potentially updating hundreds or thousands of combined entities and attributes as it often is with a traditional web service. One batch update in SQL Server may take a fraction of a second given a good highly-parameterized query, table-valued parameter or bulk insert to a staging table; processing all of these updates one at a time is slow, slow, slow, and OLTP database hardware is the most expensive of all to scale up/out. Is there some way to reconcile these competing concerns? Am I thinking about it the wrong way? Does this problem have a well-known solution in the CQS/ESB world? If not, then how does one decide what the "right level" of granularity in a Command should be? Is there some "standard" one can use as a starting point - sort of like 3NF in databases - and only deviate when careful profiling suggests a potentially significant performance benefit? Or is this possibly one of those things that, despite several strong opinions being expressed by various experts, is really just a matter of opinion?

• Use Expressions with LINQ to Entities

  - by EltonStoneman

  [Source: http://geekswithblogs.net/EltonStoneman] Recently I've been putting together a generic approach for paging the response from a WCF service. Paging changes the service signature, so it's not as simple as adding a behavior to an existing service in config, but the complexity of the paging is isolated in a generic base class. We're using the Entity Framework talking to SQL Server, so when we ask for a page using LINQ's .Take() method we get a nice efficient SQL query for just the rows we want, with minimal impact on SQL Server and network traffic. We use the maximum ID of the record returned as a high-water mark (rather than using .Skip() to go to the next record), so the approach caters for records being deleted between page requests. In the paged response we include a HasMorePages indicator, computed by comparing the max ID in the page of results to the max ID for the whole resultset - if the latter is bigger, then there are more pages. In some quick performance testing, the paged version of the service performed much more slowly than the unpaged version, which was unexpected. We narrowed it down to the code which gets the max ID for the full resultset - instead of building an efficient MAX() SQL query, EF was returning the whole resultset and then computing the max ID in the service layer. It's easy to reproduce - take this AdventureWorks query:             var context = new AdventureWorksEntities();             var query = from od in context.SalesOrderDetail                         where od.ModifiedDate >= modified                          && od.SalesOrderDetailID.CompareTo(id) > 0                         orderby od.SalesOrderDetailID                         select od;   We can find the maximum SalesOrderDetailID like this:             var maxIdEfficiently = query.Max(od => od.SalesOrderDetailID);   which produces our efficient MAX() SQL query. If we're doing this generically and we already have the ID function in a Func:             Func<SalesOrderDetail, int> idFunc = od => od.SalesOrderDetailID;             var maxIdInefficiently = query.Max(idFunc);   This fetches all the results from the query and then runs the Max() function in code. If you look at the difference in Reflector, the first call passes an Expression to the Max(), while the second call passes a Func. So it's an easy fix - wrap the Func in an Expression:             Expression<Func<SalesOrderDetail, int>> idExpression = od => od.SalesOrderDetailID;             var maxIdEfficientlyAgain = query.Max(idExpression);   - and we're back to running an efficient MAX() statement. Evidently the EF provider can dissect an Expression and build its equivalent in SQL, but it can't do that with Funcs.

• TransportWithMessageCredential & Service Bus – Introduction

  - by Michael Stephenson

  Recently we have been working on a project using the Windows Azure Service Bus to expose line of business applications. One of the topics we discussed a lot was around the security aspects of the solution. Most of the samples you see for Windows Azure Service Bus often use the shared secret with the Access Control Service to protect the service bus endpoint but one of the problems we found was that with this scenario any claims resulting from credentials supplied by the client are not passed through to the service listening to the service bus endpoint. As an example of this we originally were hoping that we could give two different clients their own shared secret key and the issuer for each would indicate which client it was. If the claims had flown to the listening service then we could check that the message sent by client one was a type they are allowed to send. Unfortunately this claim isn't flown to the listening service so we were unable to implement this scenario. We had also seen samples that talk about changing the relayClientAuthenticationType attribute would allow you to authenticate the client within the service itself rather than with ACS. While this was interesting it wasn't exactly what we wanted. By removing the step where access to the Relay endpoint is protected by authentication against ACS it means that anyone could send messages via the service bus to the on-premise listening service which would then authenticate clients. In our scenario we certainly didn't want to allow clients to skip the ACS authentication step because this could open up two attack opportunities for an attacker. The first of these would allow an attacker to send messages through to our on-premise servers and potentially cause a denial of service situation. The second case would be with the same kind of attack by running lots of messages through service bus which were then rejected the attacker would be causing us to incur charges per message on our Windows Azure account. The correct way to implement our desired scenario is to combine one of the common options for authenticating against ACS so the service bus endpoint cannot be accessed by an unauthenticated caller with the normal WCF security features using the TransportWithMessageCredential security option. Looking around I could not find any guidance on how to implement this correctly so on the back of setting this up I decided to write a couple of articles to walk through a couple of the common scenarios you may be interested in. These are available on the following links: Walkthrough - Combining shared secret and username token Walkthrough – Combining shared secret and certificates

• BizTalk Orchestration & Port Tutorial Part 2

  - by bosuch

  In Part 1 I showed how to create and publish a simple Orchestration demo. Now we’ll finish configuring it in the admin console and test it. Open the BizTalk Server 2009 Administration Console, and expand BizTalk Server 2009 Administration, then Applications. You should have an entry for OrchestrationPortDemo – expand it as well. First, we’ll add the Receive Port – the place that we’ll drop the test file. Right-click on Receive Ports and select New One-way Receive Port. On the General tab, name it InputPort, then click over to Receive Locations.   Click New to add a new location. Your receive location can be FTP, SQL, WCF, SharePoint, or many other choices, but for this demo we’ll add a File location. Click the Configure button and set a receive folder (something like “C:\PortDemo\”) and a file mask (stick with “*.xml” for now) and click OK three times to create your Receive Port.   Next we’ll create the Send port – the location where BizTalk will drop the file. Right-click on Send Ports and choose New Static One-way Send Port. Give it an appropriate name, and configure the FILE Transport Properties as shown:   Click OK twice and your Send Port will be created. Now we’ll configure the Orchestration Bindings. Click on Orchestrations, then right-click the orchestration itself and select Properties. Select the Bindings tab. Choose BizTalkServerApplication as the host, and select the Send and Receive ports you previously created, as shown:   Now it’s time to fire everything up. Right-click on the send port you created and click Start. Once the Status column displays “Started”, click on Receive Locations and Enable the Receive Location previously created. Finally, start the Orchestration. Now, time to test! Create a simple xml file like: <root>    <Node1>Test</Node1>    <Node2>Test</Node2> </root> And drop it into the C:\PortDemo folder. After a couple of seconds the file should disappear – this indicates BizTalk has picked it up for processing. Look in the C:\PortDemo\Output folder and you should see an xml file with a GUID for a name, like {7C50104F-FC3E-4A49-B2FA-4F560A37636D}.xml. Open it to verify that it matches your input file. Practically, this demo doesn’t do a whole heck of a lot, but it shows you the basics for building, publishing and running an orchestration.

• Getting Started Building Windows 8 Store Apps with XAML/C#

  - by dwahlin

  Technology is fun isn’t it? As soon as you think you’ve figured out where things are heading a new technology comes onto the scene, changes things up, and offers new opportunities. One of the new technologies I’ve been spending quite a bit of time with lately is Windows 8 store applications. I posted my thoughts about Windows 8 during the BUILD conference in 2011 and still feel excited about the opportunity there. Time will tell how well it ends up being accepted by consumers but I’m hopeful that it’ll take off. I currently have two Windows 8 store application concepts I’m working on with one being built in XAML/C# and another in HTML/JavaScript. I really like that Microsoft supports both options since it caters to a variety of developers and makes it easy to get started regardless if you’re a desktop developer or Web developer. Here’s a quick look at how the technologies are organized in Windows 8: In this post I’ll focus on the basics of Windows 8 store XAML/C# apps by looking at features, files, and code provided by Visual Studio projects. To get started building these types of apps you’ll definitely need to have some knowledge of XAML and C#. Let’s get started by looking at the Windows 8 store project types available in Visual Studio 2012.   Windows 8 Store XAML/C# Project Types When you open Visual Studio 2012 you’ll see a new entry under C# named Windows Store. It includes 6 different project types as shown next.   The Blank App project provides initial starter code and a single page whereas the Grid App and Split App templates provide quite a bit more code as well as multiple pages for your application. The other projects available can be be used to create a class library project that runs in Windows 8 store apps, a WinRT component such as a custom control, and a unit test library project respectively. If you’re building an application that displays data in groups using the “tile” concept then the Grid App or Split App project templates are a good place to start. An example of the initial screens generated by each project is shown next: Grid App Split View App   When a user clicks a tile in a Grid App they can view details about the tile data. With a Split View app groups/categories are shown and when the user clicks on a group they can see a list of all the different items and then drill-down into them:   For the remainder of this post I’ll focus on functionality provided by the Blank App project since it provides a simple way to get started learning the fundamentals of building Windows 8 store apps.   Blank App Project Walkthrough The Blank App project is a great place to start since it’s simple and lets you focus on the basics. In this post I’ll focus on what it provides you out of the box and cover additional details in future posts. Once you have the basics down you can move to the other project types if you need the functionality they provide. The Blank App project template does exactly what it says – you get an empty project with a few starter files added to help get you going. This is a good option if you’ll be building an app that doesn’t fit into the grid layout view that you see a lot of Windows 8 store apps following (such as on the Windows 8 start screen). I ended up starting with the Blank App project template for the app I’m currently working on since I’m not displaying data/image tiles (something the Grid App project does well) or drilling down into lists of data (functionality that the Split App project provides). The Blank App project provides images for the tiles and splash screen (you’ll definitely want to change these), a StandardStyles.xaml resource dictionary that includes a lot of helpful styles such as buttons for the AppBar (a special type of menu in Windows 8 store apps), an App.xaml file, and the app’s main page which is named MainPage.xaml. It also adds a Package.appxmanifest that is used to define functionality that your app requires, app information used in the store, plus more. The App.xaml, App.xaml.cs and StandardStyles.xaml Files The App.xaml file handles loading a resource dictionary named StandardStyles.xaml which has several key styles used throughout the application: <Application x:Class="BlankApp.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:BlankApp"> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <!-- Styles that define common aspects of the platform look and feel Required by Visual Studio project and item templates --> <ResourceDictionary Source="Common/StandardStyles.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application>   StandardStyles.xaml has style definitions for different text styles and AppBar buttons. If you scroll down toward the middle of the file you’ll see that many AppBar button styles are included such as one for an edit icon. Button styles like this can be used to quickly and easily add icons/buttons into your application without having to be an expert in design. <Style x:Key="EditAppBarButtonStyle" TargetType="ButtonBase" BasedOn="{StaticResource AppBarButtonStyle}"> <Setter Property="AutomationProperties.AutomationId" Value="EditAppBarButton"/> <Setter Property="AutomationProperties.Name" Value="Edit"/> <Setter Property="Content" Value="&#xE104;"/> </Style> Switching over to App.xaml.cs, it includes some code to help get you started. An OnLaunched() method is added to handle creating a Frame that child pages such as MainPage.xaml can be loaded into. The Frame has the same overall purpose as the one found in WPF and Silverlight applications - it’s used to navigate between pages in an application. /// <summary> /// Invoked when the application is launched normally by the end user. Other entry points /// will be used when the application is launched to open a specific file, to display /// search results, and so forth. /// </summary> /// <param name="args">Details about the launch request and process.</param> protected override void OnLaunched(LaunchActivatedEventArgs args) { Frame rootFrame = Window.Current.Content as Frame; // Do not repeat app initialization when the Window already has content, // just ensure that the window is active if (rootFrame == null) { // Create a Frame to act as the navigation context and navigate to the first page rootFrame = new Frame(); if (args.PreviousExecutionState == ApplicationExecutionState.Terminated) { //TODO: Load state from previously suspended application } // Place the frame in the current Window Window.Current.Content = rootFrame; } if (rootFrame.Content == null) { // When the navigation stack isn't restored navigate to the first page, // configuring the new page by passing required information as a navigation // parameter if (!rootFrame.Navigate(typeof(MainPage), args.Arguments)) { throw new Exception("Failed to create initial page"); } } // Ensure the current window is active Window.Current.Activate(); }   Notice that in addition to creating a Frame the code also checks to see if the app was previously terminated so that you can load any state/data that the user may need when the app is launched again. If you’re new to the lifecycle of Windows 8 store apps the following image shows how an app can be running, suspended, and terminated.   If the user switches from an app they’re running the app will be suspended in memory. The app may stay suspended or may be terminated depending on how much memory the OS thinks it needs so it’s important to save state in case the application is ultimately terminated and has to be started fresh. Although I won’t cover saving application state here, additional information can be found at http://msdn.microsoft.com/en-us/library/windows/apps/xaml/hh465099.aspx. Another method in App.xaml.cs named OnSuspending() is also included in App.xaml.cs that can be used to store state as the user switches to another application:   /// <summary> /// Invoked when application execution is being suspended. Application state is saved /// without knowing whether the application will be terminated or resumed with the contents /// of memory still intact. /// </summary> /// <param name="sender">The source of the suspend request.</param> /// <param name="e">Details about the suspend request.</param> private void OnSuspending(object sender, SuspendingEventArgs e) { var deferral = e.SuspendingOperation.GetDeferral(); //TODO: Save application state and stop any background activity deferral.Complete(); } The MainPage.xaml and MainPage.xaml.cs Files The Blank App project adds a file named MainPage.xaml that acts as the initial screen for the application. It doesn’t include anything aside from an empty <Grid> XAML element in it. The code-behind class named MainPage.xaml.cs includes a constructor as well as a method named OnNavigatedTo() that is called once the page is displayed in the frame.   /// <summary> /// An empty page that can be used on its own or navigated to within a Frame. /// </summary> public sealed partial class MainPage : Page { public MainPage() { this.InitializeComponent(); } /// <summary> /// Invoked when this page is about to be displayed in a Frame. /// </summary> /// <param name="e">Event data that describes how this page was reached. The Parameter /// property is typically used to configure the page.</param> protected override void OnNavigatedTo(NavigationEventArgs e) { } }   If you’re experienced with XAML you can switch to Design mode and start dragging and dropping XAML controls from the ToolBox in Visual Studio. If you prefer to type XAML you can do that as well in the XAML editor or while in split mode. Many of the controls available in WPF and Silverlight are included such as Canvas, Grid, StackPanel, and Border for layout. Standard input controls are also included such as TextBox, CheckBox, PasswordBox, RadioButton, ComboBox, ListBox, and more. MediaElement is available for rendering video or playing audio files. Some of the “common” XAML controls included out of the box are shown next:   Although XAML/C# Windows 8 store apps don’t include all of the functionality available in Silverlight 5, the core functionality required to build store apps is there with additional functionality available in open source projects such as Callisto (started by Microsoft’s Tim Heuer), Q42.WinRT, and others. Standard XAML data binding can be used to bind C# objects to controls, converters can be used to manipulate data during the data binding process, and custom styles and templates can be applied to controls to modify them. Although Visual Studio 2012 doesn’t support visually creating styles or templates, Expression Blend 5 handles that very well. To get started building the initial screen of a Windows 8 app you can start adding controls as mentioned earlier. Simply place them inside of the <Grid> element that’s included. You can arrange controls in a stacked manner using the StackPanel control, add a border around controls using the Border control, arrange controls in columns and rows using the Grid control, or absolutely position controls using the Canvas control. One of the controls that may be new to you is the AppBar. It can be used to add menu/toolbar functionality into a store app and keep the app clean and focused. You can place an AppBar at the top or bottom of the screen. A user on a touch device can swipe up to display the bottom AppBar or right-click when using a mouse. An example of defining an AppBar that contains an Edit button is shown next. The EditAppBarButtonStyle is available in the StandardStyles.xaml file mentioned earlier. <Page.BottomAppBar> <AppBar x:Name="ApplicationAppBar" Padding="10,0,10,0" AutomationProperties.Name="Bottom App Bar"> <Grid> <StackPanel x:Name="RightPanel" Orientation="Horizontal" Grid.Column="1" HorizontalAlignment="Right"> <Button x:Name="Edit" Style="{StaticResource EditAppBarButtonStyle}" Tag="Edit" /> </StackPanel> </Grid> </AppBar> </Page.BottomAppBar> Like standard XAML controls, the <Button> control in the AppBar can be wired to an event handler method in the MainPage.Xaml.cs file or even bound to a ViewModel object using “commanding” if your app follows the Model-View-ViewModel (MVVM) pattern (check out the MVVM Light package available through NuGet if you’re using MVVM with Windows 8 store apps). The AppBar can be used to navigate to different screens, show and hide controls, display dialogs, show settings screens, and more.   The Package.appxmanifest File The Package.appxmanifest file contains configuration details about your Windows 8 store app. By double-clicking it in Visual Studio you can define the splash screen image, small and wide logo images used for tiles on the start screen, orientation information, and more. You can also define what capabilities the app has such as if it uses the Internet, supports geolocation functionality, requires a microphone or webcam, etc. App declarations such as background processes, file picker functionality, and sharing can also be defined Finally, information about how the app is packaged for deployment to the store can also be defined. Summary If you already have some experience working with XAML technologies you’ll find that getting started building Windows 8 applications is pretty straightforward. Many of the controls available in Silverlight and WPF are available making it easy to get started without having to relearn a lot of new technologies. In the next post in this series I’ll discuss additional features that can be used in your Windows 8 store apps.

• Metro, Authentication, and the ASP.NET Web API

  - by Stephen.Walther

  Imagine that you want to create a Metro style app written with JavaScript and you want to communicate with a remote web service. For example, you are creating a movie app which retrieves a list of movies from a movies service. In this situation, how do you authenticate your Metro app and the Metro user so not just anyone can call the movies service? How can you identify the user making the request so you can return user specific data from the service? The Windows Live SDK supports a feature named Single Sign-On. When a user logs into a Windows 8 machine using their Live ID, you can authenticate the user’s identity automatically. Even better, when the Metro app performs a call to a remote web service, you can pass an authentication token to the remote service and prevent unauthorized access to the service. The documentation for Single Sign-On is located here: http://msdn.microsoft.com/en-us/library/live/hh826544.aspx In this blog entry, I describe the steps that you need to follow to use Single Sign-On with a (very) simple movie app. We build a Metro app which communicates with a web service created using the ASP.NET Web API. Creating the Visual Studio Solution Let’s start by creating a Visual Studio solution which contains two projects: a Windows Metro style Blank App project and an ASP.NET MVC 4 Web Application project. Name the Metro app MovieApp and the ASP.NET MVC application MovieApp.Services. When you create the ASP.NET MVC application, select the Web API template: After you create the two projects, your Visual Studio Solution Explorer window should look like this: Configuring the Live SDK You need to get your hands on the Live SDK and register your Metro app. You can download the latest version of the SDK (version 5.2) from the following address: http://www.microsoft.com/en-us/download/details.aspx?id=29938 After you download the Live SDK, you need to visit the following website to register your Metro app: https://manage.dev.live.com/build Don’t let the title of the website — Windows Push Notifications & Live Connect – confuse you, this is the right place. Follow the instructions at the website to register your Metro app. Don’t forget to follow the instructions in Step 3 for updating the information in your Metro app’s manifest. After you register, your client secret is displayed. Record this client secret because you will need it later (we use it with the web service): You need to configure one more thing. You must enter your Redirect Domain by visiting the following website: https://manage.dev.live.com/Applications/Index Click on your application name, click Edit Settings, click the API Settings tab, and enter a value for the Redirect Domain field. You can enter any domain that you please just as long as the domain has not already been taken: For the Redirect Domain, I entered http://superexpertmovieapp.com. Create the Metro MovieApp Next, we need to create the MovieApp. The MovieApp will: 1. Use Single Sign-On to log the current user into Live 2. Call the MoviesService web service 3. Display the results in a ListView control Because we use the Live SDK in the MovieApp, we need to add a reference to it. Right-click your References folder in the Solution Explorer window and add the reference: Here’s the HTML page for the Metro App: <!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>MovieApp</title> <!-- WinJS references --> <link href="//Microsoft.WinJS.1.0.RC/css/ui-dark.css" rel="stylesheet" /> <script src="//Microsoft.WinJS.1.0.RC/js/base.js"></script> <script src="//Microsoft.WinJS.1.0.RC/js/ui.js"></script> <!-- Live SDK --> <script type="text/javascript" src="/LiveSDKHTML/js/wl.js"></script> <!-- WebServices references --> <link href="/css/default.css" rel="stylesheet" /> <script src="/js/default.js"></script> </head> <body> <div id="tmplMovie" data-win-control="WinJS.Binding.Template"> <div class="movieItem"> <span data-win-bind="innerText:title"></span> <br /><span data-win-bind="innerText:director"></span> </div> </div> <div id="lvMovies" data-win-control="WinJS.UI.ListView" data-win-options="{ itemTemplate: select('#tmplMovie') }"> </div> </body> </html> The HTML page above contains a Template and ListView control. These controls are used to display the movies when the movies are returned from the movies service. Notice that the page includes a reference to the Live script that we registered earlier: <!-- Live SDK --> <script type="text/javascript" src="/LiveSDKHTML/js/wl.js"></script> The JavaScript code looks like this: (function () { "use strict"; var REDIRECT_DOMAIN = "http://superexpertmovieapp.com"; var WEBSERVICE_URL = "http://localhost:49743/api/movies"; function init() { WinJS.UI.processAll().done(function () { // Get element and control references var lvMovies = document.getElementById("lvMovies").winControl; // Login to Windows Live var scopes = ["wl.signin"]; WL.init({ scope: scopes, redirect_uri: REDIRECT_DOMAIN }); WL.login().then( function(response) { // Get the authentication token var authenticationToken = response.session.authentication_token; // Call the web service var options = { url: WEBSERVICE_URL, headers: { authenticationToken: authenticationToken } }; WinJS.xhr(options).done( function (xhr) { var movies = JSON.parse(xhr.response); var listMovies = new WinJS.Binding.List(movies); lvMovies.itemDataSource = listMovies.dataSource; }, function (xhr) { console.log(xhr.statusText); } ); }, function(response) { throw WinJS.ErrorFromName("Failed to login!"); } ); }); } document.addEventListener("DOMContentLoaded", init); })(); There are two constants which you need to set to get the code above to work: REDIRECT_DOMAIN and WEBSERVICE_URL. The REDIRECT_DOMAIN is the domain that you entered when registering your app with Live. The WEBSERVICE_URL is the path to your web service. You can get the correct value for WEBSERVICE_URL by opening the Project Properties for the MovieApp.Services project, clicking the Web tab, and getting the correct URL. The port number is randomly generated. In my code, I used the URL  “http://localhost:49743/api/movies”. Assuming that the user is logged into Windows 8 with a Live account, when the user runs the MovieApp, the user is logged into Live automatically. The user is logged in with the following code: // Login to Windows Live var scopes = ["wl.signin"]; WL.init({ scope: scopes, redirect_uri: REDIRECT_DOMAIN }); WL.login().then(function(response) { // Do something }); The scopes setting determines what the user has permission to do. For example, access the user’s SkyDrive or access the user’s calendar or contacts. The available scopes are listed here: http://msdn.microsoft.com/en-us/library/live/hh243646.aspx In our case, we only need the wl.signin scope which enables Single Sign-On. After the user signs in, you can retrieve the user’s Live authentication token. The authentication token is passed to the movies service to authenticate the user. Creating the Movies Service The Movies Service is implemented as an API controller in an ASP.NET MVC 4 Web API project. Here’s what the MoviesController looks like: using System.Collections.Generic; using System.Linq; using System.Net; using System.Net.Http; using System.Web.Http; using JWTSample; using MovieApp.Services.Models; namespace MovieApp.Services.Controllers { public class MoviesController : ApiController { const string CLIENT_SECRET = "NtxjF2wu7JeY1unvVN-lb0hoeWOMUFoR"; // GET api/values public HttpResponseMessage Get() { // Authenticate // Get authenticationToken var authenticationToken = Request.Headers.GetValues("authenticationToken").FirstOrDefault(); if (authenticationToken == null) { return new HttpResponseMessage(HttpStatusCode.Unauthorized); } // Validate token var d = new Dictionary<int, string>(); d.Add(0, CLIENT_SECRET); try { var myJWT = new JsonWebToken(authenticationToken, d); } catch { return new HttpResponseMessage(HttpStatusCode.Unauthorized); } // Return results return Request.CreateResponse( HttpStatusCode.OK, new List<Movie> { new Movie {Title="Star Wars", Director="Lucas"}, new Movie {Title="King Kong", Director="Jackson"}, new Movie {Title="Memento", Director="Nolan"} } ); } } } Because the Metro app performs an HTTP GET request, the MovieController Get() action is invoked. This action returns a set of three movies when, and only when, the authentication token is validated. The Movie class looks like this: using Newtonsoft.Json; namespace MovieApp.Services.Models { public class Movie { [JsonProperty(PropertyName="title")] public string Title { get; set; } [JsonProperty(PropertyName="director")] public string Director { get; set; } } } Notice that the Movie class uses the JsonProperty attribute to change Title to title and Director to director to make JavaScript developers happy. The Get() method validates the authentication token before returning the movies to the Metro app. To get authentication to work, you need to provide the client secret which you created at the Live management site. If you forgot to write down the secret, you can get it again here: https://manage.dev.live.com/Applications/Index The client secret is assigned to a constant at the top of the MoviesController class. The MoviesController class uses a helper class named JsonWebToken to validate the authentication token. This class was created by the Windows Live team. You can get the source code for the JsonWebToken class from the following GitHub repository: https://github.com/liveservices/LiveSDK/blob/master/Samples/Asp.net/AuthenticationTokenSample/JsonWebToken.cs You need to add an additional reference to your MVC project to use the JsonWebToken class: System.Runtime.Serialization. You can use the JsonWebToken class to get a unique and validated user ID like this: var user = myJWT.Claims.UserId; If you need to store user specific information then you can use the UserId property to uniquely identify the user making the web service call. Running the MovieApp When you first run the Metro MovieApp, you get a screen which asks whether the app should have permission to use Single Sign-On. This screen never appears again after you give permission once. Actually, when I first ran the app, I get the following error: According to the error, the app is blocked because “We detected some suspicious activity with your Online Id account. To help protect you, we’ve temporarily blocked your account.” This appears to be a bug in the current preview release of the Live SDK and there is more information about this bug here: http://social.msdn.microsoft.com/Forums/en-US/messengerconnect/thread/866c495f-2127-429d-ab07-842ef84f16ae/ If you click continue, and continue running the app, the error message does not appear again.  Summary The goal of this blog entry was to describe how you can validate Metro apps and Metro users when performing a call to a remote web service. First, I explained how you can create a Metro app which takes advantage of Single Sign-On to authenticate the current user against Live automatically. You learned how to register your Metro app with Live and how to include an authentication token in an Ajax call. Next, I explained how you can validate the authentication token – retrieved from the request header – in a web service. I discussed how you can use the JsonWebToken class to validate the authentication token and retrieve the unique user ID.

• HowTo import Certificate (pfx) with private key in WinXP

  - by Gunther

  Hello, I tried the whole day just to import a cetrificate in winXP, but I allways failed. I did following: Create the certificate with private key (no pasword): makecert -sr LocalMachine -ss My -pe -sky exchange -n "CN=TestCert" -a sha1 -sv TestCert.pvk TestCert.cer Then put certificate and private key together into pfx file: pvk2pfx.exe -pvk TestCert.pvk -spc TestCert.cer -pfx TestCert.pfx Import pfx file with commandline tool (German System): winhttpcertcfg.exe -i TestCert.pfx -a NT-AUTORITÄT\NETZWERKDIENST -c LOCAL_MACHINE\My Error: Unable to import contents of PFX file. Please make sure the filename and path, as well as the password, are correct. Hint: "NT-AUTORITÄT\NETZWERKDIENST" -- "NT-AUTHORITY\NETWORKSERVICE" Filename is ok, password was not set. Even if I set the password (e.g. "MyPassword") in Step 1 and type at the end of step 3: ... -p MyPassword I got the same error. Then I tried to import in the certificate console (mmc with certificate snap-in). There i got following error: "Der private Schlüssel, den Sie importieren, erfordert möglicherweise einen Dienstanbieter, der nicht installiert ist." -- "The imported private key may requires a service-supplier which is not installed". But the Microsoft Crypto-Service is up and running. What else can I do? On Windows Vista and Windows 7 I got this running without these problems. I need this Certificate to run a WCF Service. Thanks in advance for any hint. Regards, Gunther

• Cannot start listening on a certain TCP port, but there's nothing currently listening on it

  - by John Rasch

  I have Windows Service that uses a WCF service host to listen for connections on TCP port 61000. When I try to start the service, I get the error: Service cannot be started. System.ServiceModel.AddressAlreadyInUseException: HTTP could not register URL http://+:61000/ because TCP port 61000 is being used by another application. ---> System.Net.HttpListenerException: The process cannot access the file because it is being used by another process at System.Net.HttpListener.AddAll() at System.Net.HttpListener.Start() at System.ServiceModel.Channels.SharedHttpTransportManager.OnOpen() --- End of inner exception stack trace --- at System.ServiceModel.Channels.SharedHttpTransportManager.OnOpen() at System.ServiceModel.Channels.TransportManager.Open(TransportChannelListener channelListener) at System.ServiceModel.Channels.TransportManagerContainer.Open(SelectTransportManagersCallback selectTransportManagerCallback) at System.ServiceModel.Channels.HttpChannelListener.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.Dispatcher.ChannelDispatcher.OnOpen(TimeSpan timeout) at... A quick netstat -a shows there is nothing listening on port 61000. I've also found several posts online that mention reserving namespaces using netstat, but the account that the service runs under has administrator privileges so that shouldn't be necessary. Any other ideas as to why I'm getting this message? This service is running on 64-bit Windows Server 2008 R2 Standard.

• What should I do to make sure that IIS does not recycle my application?

  - by AngryHacker

  I have a WCF service app hosted in IIS. On startup, it goes and fetches a really expensive (in terms of time and cpu) resource to use as local cache. Unfortunately, IIS seems to recycle the process on a fairly regular basis. So I am trying to change the settings on the Application Pool to make sure that IIS does not recycle the application. So far, I've change the following: Limit Interval under CPU from 5 to 0. Idle Time-out under Process Model from 20 to 0. Regular Time Interval under Recycling from 1740 to 0. Will this be enough? And I have specific questions about the items I changed: What specifically does Limit Interval setting under CPU mean? Does it mean that if a certain CPU usage is exceeded, the application pool will be recycled? What exactly does "recycled" mean? Is the application completely torn down and started up again? What is the difference between "Worker Process shutdown" and "Application Pool recycling"? The documentation for the Idle Time-out under Process Model talks about shutting down the worker process. While the docs for Regular Time Interval under Recycling talk about application pool recycling. I don't quite grok the difference between the two. I thought the w3wp.exe is the worker process which runs the application pool. Can someone explain the difference to the application between the two? The reason for having IIS7 and IIS7.5 tags is because the app will run in both and hope the answers are the same between the versions. Image for reference:

• Handling HumanTask attachments in Oracle BPM 11g PS4FP+ (II)

  - by ccasares

  Retrieving uploaded attachments -UCM- As stated in my previous blog entry, Oracle BPM 11g 11.1.1.5.1 (aka PS4FP) introduced a new cool feature whereby you can use Oracle WebCenter Content (previously known as Oracle UCM) as the repository for the human task attached documents. For more information about how to use or enable this feature, have a look here. The attachment scope (either TASK or PROCESS) also applies to UCM-attachments. But even with this other feature, one question might arise when using UCM attachments. How can I get them from within the process? The first answer would be to use the same getTaskAttachmentContents() XPath function already explained in my previous blog entry. In fact, that's the way it should be. But in Oracle BPM 11g 11.1.1.5.1 (PS4FP) and 11.1.1.6.0 (PS5) there's a bug that prevents you to do that. If you invoke such function against a UCM-attachment, you'll get a null content response (bug#13907552). Even if the attachment was correctly uploaded. While this bug gets fixed, next I will show a workaround that lets me to retrieve the UCM-attached documents from within a BPM process. Besides, the sample will show how to interact with WCC API from within a BPM process.Aside note: I suggest you to read my previous blog entry about Human Task attachments where I briefly describe some concepts that are used next, such as the execData/attachment[] structure. Sample Process I will be using the following sample process: A dummy UserTask using "HumanTask2" Human Task, followed by an Embedded Subprocess that will retrieve the attachments payload. In this case, and here's the key point of the sample, we will retrieve such payload using WebCenter Content WebService API (IDC): and once retrieved, we will write each of them back to a file in the server using a File Adapter service: In detail:  We will use the same attachmentCollection XSD structure and same BusinessObject definition as in the previous blog entry. However we create a separate variable, named attachmentUCM, based on such BusinessObject. We will still need to keep a copy of the HumanTask output's execData structure. Therefore we need to create a new variable of type TaskExecutionData (different one than the other used for non-UCM attachments): As in the non-UCM attachments flow, in the output tab of the UserTask mapping, we'll keep a copy of the execData structure: Now we get into the embedded subprocess that will retrieve the attachments' payload. First, and using an XSLT transformation, we feed the attachmentUCM variable with the following information: The name of each attachment (from execData/attachment/name element) The WebCenter Content ID of the uploaded attachment. This info is stored in execData/attachment/URI element with the format ecm://<id>. As we just want the numeric <id>, we need to get rid of the protocol prefix ("ecm://"). We do so with some XPath functions as detailed below: with these two functions being invoked, respectively: We, again, set the target payload element with an empty string, to get the <payload></payload> tag created. The complete XSLT transformation is shown below. Remember that we're using the XSLT for-each node to create as many target structures as necessary.  Once we have fed the attachmentsUCM structure and so it now contains the name of each of the attachments along with each WCC unique id (dID), it is time to iterate through it and get the payload. Therefore we will use a new embedded subprocess of type MultiInstance, that will iterate over the attachmentsUCM/attachment[] element: In each iteration we will use a Service activity that invokes WCC API through a WebService. Follow these steps to create and configure the Partner Link needed: Login to WCC console with an administrator user (i.e. weblogic). Go to Administration menu and click on "Soap Wsdls" link. We will use the GetFile service to retrieve a file based on its dID. Thus we'll need such service WSDL definition that can be downloaded by clicking the GetFile link. Save the WSDL file in your JDev project folder. In the BPM project's composite view, drag & drop a WebService adapter to create a new External Reference, based on the just added GetFile.wsdl. Name it UCM_GetFile. WCC services are secured through basic HTTP authentication. Therefore we need to enable the just created reference for that: Right-click the reference and click on Configure WS Policies. Under the Security section, click "+" to add the "oracle/wss_username_token_client_policy" policy The last step is to set the credentials for the security policy. For the sample we will use the admin user for WCC (weblogic/welcome1). Open the composite.xml file and select the Source view. Search for the UCM_GetFile entry and add the following highlighted elements into it:   <reference name="UCM_GetFile" ui:wsdlLocation="GetFile.wsdl">     <interface.wsdl interface="http://www.stellent.com/GetFile/#wsdl.interface(GetFileSoap)"/>     <binding.ws port="http://www.stellent.com/GetFile/#wsdl.endpoint(GetFile/GetFileSoap)"                 location="GetFile.wsdl" soapVersion="1.1">       <wsp:PolicyReference URI="oracle/wss_username_token_client_policy"                            orawsp:category="security" orawsp:status="enabled"/>       <property name="weblogic.wsee.wsat.transaction.flowOption"                 type="xs:string" many="false">WSDLDriven</property>       <property name="oracle.webservices.auth.username"                 type="xs:string">weblogic</property>       <property name="oracle.webservices.auth.password"                 type="xs:string">welcome1</property>     </binding.ws>   </reference> Now the new external reference is ready: Once the reference has just been created, we should be able now to use it from our BPM process. However we find here a problem. The WCC GetFile service operation that we will use, GetFileByID, accepts as input a structure similar to this one, where all element tags are optional: <get:GetFileByID xmlns:get="http://www.stellent.com/GetFile/">    <get:dID>?</get:dID>   <get:rendition>?</get:rendition>   <get:extraProps>      <get:property>         <get:name>?</get:name>         <get:value>?</get:value>      </get:property>   </get:extraProps></get:GetFileByID> and we need to fill up just the <get:dID> tag element. Due to some kind of restriction or bug on WCC, the rest of the tag elements must NOT be sent, not even empty (i.e.: <get:rendition></get:rendition> or <get:rendition/>). A sample request that performs the query just by the dID, must be in the following format: <get:GetFileByID xmlns:get="http://www.stellent.com/GetFile/">   <get:dID>12345</get:dID></get:GetFileByID> The issue here is that the simple mapping in BPM does create empty tags being a sample result as follows: <get:GetFileByID xmlns:get="http://www.stellent.com/GetFile/"> <get:dID>12345</get:dID> <get:rendition/> <get:extraProps/> </get:GetFileByID> Although the above structure is perfectly valid, it is not accepted by WCC. Therefore, we need to bypass the problem. The workaround we use (many others are available) is to add a Mediator component between the BPM process and the Service that simply copies the input structure from BPM but getting rid of the empty tags. Follow these steps to configure the Mediator: Drag & drop a new Mediator component into the composite. Uncheck the creation of the SOAP bindings and use the Interface Definition from WSDL template and select the existing GetFile.wsdl Double click in the mediator to edit it. Add a static routing rule to the GetFileByID operation, of type Service and select References/UCM_GetFile/GetFileByID target service: Create the request and reply XSLT mappers: Make sure you map only the dID element in the request: And do an Auto-mapper for the whole response: Finally, we can now add and configure the Service activity in the BPM process. Drag & drop it to the embedded subprocess and select the NormalizedGetFile service and getFileByID operation: Map both the input: ...and the output: Once this embedded subprocess ends, we will have all attachments (name + payload) in the attachmentsUCM variable, which is the main goal of this sample. But in order to test everything runs fine, we finish the sample writing each attachment to a file. To that end we include a final embedded subprocess to concurrently iterate through each attachmentsUCM/attachment[] element: On each iteration we will use a Service activity that invokes a File Adapter write service. In here we have two important parameters to set. First, the payload itself. The file adapter awaits binary data in base64 format (string). We have to map it using XPath (Simple mapping doesn't recognize a String as a base64-binary valid target): Second, we must set the target filename using the Service Properties dialog box: Again, note how we're making use of the loopCounter index variable to get the right element within the embedded subprocess iteration. Final blog entry about attachments will handle how to inject documents to Human Tasks from the BPM process and how to share attachments between different User Tasks. Will come soon. Again, once I finish will all posts on this matter, I will upload the whole sample project to java.net.

• Stumbling Through: Visual Studio 2010 (Part I)

  Ive spent the better part of the last two years doing nothing but K2 workflow development, which until very recently could only be done in Visual Studio 2005 so I am a bit behind the times. I seem to have skipped over using Visual Studio 2008 entirely, and I am now ready to stumble through all that Ive missed. Not that I will abandon my K2 ramblings, but I need to get back to some of the other technologies I am passionate about but havent had the option of working with them on a day-to-day basis as I have with K2 blackpearl. Specifically, I am going to be focusing my efforts on what is new in the Entity Framework and WPF in Visual Studio 2010, though you have to keep in mind that since I have skipped VS 2008, I may be giving VS 2010 credit for things that really have been around for a while (hey, if I havent seen it, it is new to me!). I have the following simple goals in mind for this exercise: Entity Framework Model an inherited class Entity Framework Model a lookup entity WPF Bind a list of entities WPF - on selection of an entity in the bound list, display values of the selected entity WPF For the lookup field, provide a dropdown of potential values to lookup All of these goals must be accomplished using as little code as possible, relying on the features we get out of the box in Visual Studio 2010. This isnt going to be rocket science here, Im not even looking to get or save this data from/to a data source, but I gotta start somewhere and hopefully it will grow into something more interesting. For this exercise, I am going to try to model some fictional data about football players and personnel (maybe turning this into some sort of NFL simulation game if I lose my job and can play with this all day), so Ill start with a Person class that has a name property, and extend that with a Player class to include a Position lookup property. The idea is that a Person can be a Player, Coach or whatever other personnel type may be associated with a football team but well only flesh out the Player aspect of a person for this. So to get started, I fired up Visual Studio 2010 and created a new WPF Application: To this project, I added a new ADO.NET Entity Data Model named PlayerModel (for now, not sure what will be an appropriate name so this may be revisited): I chose for it to be an empty model, as I dont have a database designed for this yet: Using the toolbox, I dragged out an entity for each of the items we identified earlier: Person, Player and Position, and gave them some simple properties (note that I kept the default Id property for each of them): Now to figure out how to link these things together the way I want to first, lets try to tell it that Player extends Person. I see that Inheritance is one of the items in the toolbox, but I cant seem to drag it out anywhere onto the canvas. However, when I right-click an element, I get the option to Add Inheritance to it, which gives us exactly what we want: Ok, now that we have that, how do we tell it that each player has a position? Well, despite association being in the toolbox, I have learned that you cant just drag and drop those elements so I right click Player and select Add -> Association to get the following dialog: I see the option here to Add foreign key properties to my entities Ive read somewhere this this is a new and highly-sought after feature so Ill see what it does. Selecting it includes a PositionId on the Player element for me, which seems pretty database-centric and I would like to see if I can live without it for now given that we also got the Position property out of this association. Ill bring it back into the fold if it ends up being useful later. Here is what we end up with now: Trying to compile this resulted in an error stating that the Player entity cannot have an Id, because the Person element it extends already has a property named Id. Makes sense, so I remove it and compile again. Success, but with a warning but success is a good thing so Ill pretend I didnt see that warning for now. It probably has to do with the fact that my Player entity is now pretty useless as it doesnt have any non-navigation properties. So things seem to match what we are going for, great now what the heck do we do with this? Lets switch gears and see what we get for free dealing with this model from the UI. Lets open up the MainWindow.xaml and see if we can connect to our entities as a data source. Hey, whats this? Have you read my mind, Visual Studio? Our entities are already listed in the Data Sources panel: I do notice, however, that our Player entity is missing. Is this due to that compilation warning? Ill add a bogus property to our player entity just to see if that is the case no, still no love. The warning reads: Error 2062: No mapping specified for instances of the EntitySet and AssociationSet in the EntityContainer PlayerModelContainer. Well if everything worked without any issues, then I wouldnt be stumbling through at all, so lets get to the bottom of this. My good friend google indicates that the warning is due to the model not being tied up to a database. Hmmm, so why dont Players show up in my data sources? A little bit of drill-down shows that they are, in fact, exposed under Positions: Well now that isnt quite what I want. While you could get to players through a position, it shouldnt be that way exclusively. Oh well, I can ignore that for now lets drag Players out onto the canvas after selecting List from the dropdown: Hey, what the heck? I wanted a list not a listview. Get rid of that list view that was just dropped, drop in a listbox and then drop the Players entity into it. That will bind it for us. Of course, there isnt any data to show, which brings us to the really hacky part of all this and that is to stuff some test data into our view source without actually getting it from any data source. To do this through code, we need to grab a reference to the positionsPlayersViewSource resource that was created for us when we dragged out our Players entity. We then set the source of that reference equal to a populated list of Players.  Well add a couple of players that way as well as a few positions via the positionsViewSource resource, and Ill ensure that each player has a position specified.  Ultimately, the code looks like this: System.Windows.Data.CollectionViewSource positionViewSource = ((System.Windows.Data.CollectionViewSource)(this.FindResource("positionsViewSource")));             List<Position> positions = new List<Position>();             Position newPosition = new Position();             newPosition.Id = 0;             newPosition.Name = "WR";             positions.Add(newPosition);             newPosition = new Position();             newPosition.Id = 1;             newPosition.Name = "RB";             positions.Add(newPosition);             newPosition = new Position();             newPosition.Id = 2;             newPosition.Name = "QB";             positions.Add(newPosition);             positionViewSource.Source = positions;             System.Windows.Data.CollectionViewSource playerViewSource = ((System.Windows.Data.CollectionViewSource)(this.FindResource("positionsPlayersViewSource")));             List<Player> players = new List<Player>();             Player newPlayer = new Player();             newPlayer.Id = 0;             newPlayer.Name = "Test Dude";             newPlayer.Position = positions[0];             players.Add(newPlayer);             newPlayer = new Player();             newPlayer.Id = 1;             newPlayer.Name = "Test Dude II";             newPlayer.Position = positions[1];             players.Add(newPlayer);             newPlayer = new Player();             newPlayer.Id = 2;             newPlayer.Name = "Test Dude III";             newPlayer.Position = positions[2];             players.Add(newPlayer);             playerViewSource.Source = players; Now that our views are being loaded with data, we can go about tying things together visually. Drop a text box (to show the selected players name) and a combo box (to show the selected players position). Drag the Positions entity from the data sources panel to the combo box to wire it up to the positions view source. Click the text box that was dragged, and find its Text property in the properties pane. There is a little glyph next to it that displays Advanced Properties when hovered over click this and then select Apply Data Binding. In the dialog that appears, we can select the current players name as the value to bind to: Similarly, we can wire up the combo boxs SelectedItem value to the current players position: When the application is executed and we navigate through the various players, we automatically get their name and position bound to the appropriate fields: All of this was accomplished with no code save for loading the test data, and I might add, it was pretty intuitive to do so via the drag and drop of entities straight from the data sources panel. So maybe all of this was old hat to you, but I was very impressed with this experience and I look forward to stumbling through the caveats of doing more complex data modeling and binding in this fashion. Next up, I suppose, will be figuring out how to get the entities to get real data from a data source instead of stuffing it with test data as well as trying to figure out why Players ended up being under Positions in the data sources panel.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• MS Dynamics CRM users disappear

  - by Max Kosyakov

  Recently we came across quite a weird issue. The administrators say that once in a while they notice that user accounts in MS Dynamics CRM are lost . When a new user is added to the system, the administrators add him/her to the Active Directory first. Then, they go to Dynamics CRM interface, then to system configuration -> administration -> users and add the new user to the CRM, add roles to this user, grant them relevant permissions. Then the user is able to use a custom application, which connects to the Dynamics CRM via WCF. After a while (few weeks or months) the user is unable to use the custom application because Dynamics CRM cannot authorise this user. When administrators open the Dynamics CRM user management interface (configuration -> administration -> users ) and browse through the list of CRM users they cannot find the user in the list. When they try to add the user to Dynamics CRM back, the CRM fails with the error message "User already exists". Moreover, the user still exists in the Active Directory. The admins are very sure the user had been added to the CRM before he/she started to work. The only fact the the user was able to use the custom application normally says that the user had been indeed registered in the CRM. How come the user is not listed in the CRM user management interface at all? Have anyone faced any issues like that? Seen or heard of disappearing CRM users somewhere? Any help is appreciated. Where can one start digging?

• Does IIS Sometimes Allocate More Worker Processes Than Configured?

  - by Paul Williams

  We have an IIS 7.5 web service on Windows Server 2008 that handles WCF requests from C# clients. This service is configured to have Maximum Worker Processes = 1, so it is not a web garden. IIS is setup to recycle itself at the same time every day (3 AM). I am trying to debug gnarly connection issues, so I wanted to be sure the application pool was not recycling itself. I configured the pool to log an event when it recycles itself. To my surprise, I see the following entries in the System event log: Level: Information Date/Time: 3/23/2012 3:00:00 AM - Source: WAS - Event ID: 5076 A worker process with process id of '6636' serving application pool 'MyAppPool' has requested a recycle because it reached its scheduled recycle time. Level: Information Date/Time: 3/23/2012 2:59:39 AM - Source: WAS - Event ID: 5076 A worker process with process id of '9364' serving application pool 'MyAppPool' has requested a recycle because it reached its scheduled recycle time. IIS is correctly recycling the application pool at 3 AM. However, I do not understand why I would be getting two recycle events in the log within a few seconds of each other. The maximum number of processes is 1. Does IIS sometimes allocate multiple processes for an application pool that is specified as having 1 process? -- edit -- I connected at about 4 PM today and only saw 1 w3wp.exe process. There are no other event log entries that would indicate a crash.
