• IBM Websphere on Windows- OutOfMemoryError: Failed to create a thread

  - by Kishnan

  I have a J2EE application running on an IBM Websphere Application Server on a Windows Operating System. Occasionally I see an OutOfMemoryError Exception with the following information in the javacore file. 1TISIGINFO Dump Event "systhrow" (00040000) Detail "java/lang/OutOfMemoryError":"Failed to create a thread: retVal -1073741830, errno 12" received Java is run with the following configurations: -Xms512m -Xmx1350m -Xscmx50M Analyzing the javacore file, the number of threads are just 124. Analyzing the heap dump, the memory occupied by the heap is about 500Mb. Given the relatively normal number of threads and heap size a lot lower than the maximum, I am trying to figure out why I see this error? I´m not sure if this helps, but here is the top section of the javacore file...

• Hibernate unable to instantiate default tuplizer - cannot find getter

  - by ZeldaPinwheel

  I'm trying to use Hibernate to persist a class that looks like this: public class Item implements Serializable, Comparable<Item> { // Item id private Integer id; // Description of item in inventory private String description; // Number of items described by this inventory item private int count; //Category item belongs to private String category; // Date item was purchased private GregorianCalendar purchaseDate; public Item() { } public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } public int getCount() { return count; } public void setCount(int count) { this.count = count; } public String getCategory() { return category; } public void setCategory(String category) { this.category = category; } public GregorianCalendar getPurchaseDate() { return purchaseDate; } public void setPurchasedate(GregorianCalendar purchaseDate) { this.purchaseDate = purchaseDate; } My Hibernate mapping file contains the following: <property name="puchaseDate" type="java.util.GregorianCalendar"> <column name="purchase_date"></column> </property> When I try to run, I get error messages indicating there is no getter function for the purchaseDate attribute: 577 [main] INFO org.hibernate.connection.DriverManagerConnectionProvider -

• Creating a dynamic proxy generator with c# – Part 2 – Interceptor Design

  - by SeanMcAlinden

  Creating a dynamic proxy generator – Part 1 – Creating the Assembly builder, Module builder and caching mechanism For the latest code go to http://rapidioc.codeplex.com/ Before getting too involved in generating the proxy, I thought it would be worth while going through the intended design, this is important as the next step is to start creating the constructors for the proxy. Each proxy derives from a specified type The proxy has a corresponding constructor for each of the base type constructors The proxy has overrides for all methods and properties marked as Virtual on the base type For each overridden method, there is also a private method whose sole job is to call the base method. For each overridden method, a delegate is created whose sole job is to call the private method that calls the base method. The following class diagram shows the main classes and interfaces involved in the interception process. I’ll go through each of them to explain their place in the overall proxy.   IProxy Interface The proxy implements the IProxy interface for the sole purpose of adding custom interceptors. This allows the created proxy interface to be cast as an IProxy and then simply add Interceptors by calling it’s AddInterceptor method. This is done internally within the proxy building process so the consumer of the API doesn’t need knowledge of this. IInterceptor Interface The IInterceptor interface has one method: Handle. The handle method accepts a IMethodInvocation parameter which contains methods and data for handling method interception. Multiple classes that implement this interface can be added to the proxy. Each method override in the proxy calls the handle method rather than simply calling the base method. How the proxy fully works will be explained in the next section MethodInvocation. IMethodInvocation Interface & MethodInvocation class The MethodInvocation will contain one main method and multiple helper properties. Continue Method The method Continue() has two functions hidden away from the consumer. When Continue is called, if there are multiple Interceptors, the next Interceptors Handle method is called. If all Interceptors Handle methods have been called, the Continue method then calls the base class method. Properties The MethodInvocation will contain multiple helper properties including at least the following: Method Name (Read Only) Method Arguments (Read and Write) Method Argument Types (Read Only) Method Result (Read and Write) – this property remains null if the method return type is void Target Object (Read Only) Return Type (Read Only) DefaultInterceptor class The DefaultInterceptor class is a simple class that implements the IInterceptor interface. Here is the code: DefaultInterceptor namespace Rapid.DynamicProxy.Interception {     /// <summary>     /// Default interceptor for the proxy.     /// </summary>     /// <typeparam name="TBase">The base type.</typeparam>     public class DefaultInterceptor<TBase> : IInterceptor<TBase> where TBase : class     {         /// <summary>         /// Handles the specified method invocation.         /// </summary>         /// <param name="methodInvocation">The method invocation.</param>         public void Handle(IMethodInvocation<TBase> methodInvocation)         {             methodInvocation.Continue();         }     } } This is automatically created in the proxy and is the first interceptor that each method override calls. It’s sole function is to ensure that if no interceptors have been added, the base method is still called. Custom Interceptor Example A consumer of the Rapid.DynamicProxy API could create an interceptor for logging when the FirstName property of the User class is set. Just for illustration, I have also wrapped a transaction around the methodInvocation.Coninue() method. This means that any overriden methods within the user class will run within a transaction scope. MyInterceptor public class MyInterceptor : IInterceptor<User<int, IRepository>> {     public void Handle(IMethodInvocation<User<int, IRepository>> methodInvocation)     {         if (methodInvocation.Name == "set_FirstName")         {             Logger.Log("First name seting to: " + methodInvocation.Arguments[0]);         }         using (TransactionScope scope = new TransactionScope())         {             methodInvocation.Continue();         }         if (methodInvocation.Name == "set_FirstName")         {             Logger.Log("First name has been set to: " + methodInvocation.Arguments[0]);         }     } } Overridden Method Example To show a taster of what the overridden methods on the proxy would look like, the setter method for the property FirstName used in the above example would look something similar to the following (this is not real code but will look similar): set_FirstName public override void set_FirstName(string value) {     set_FirstNameBaseMethodDelegate callBase =         new set_FirstNameBaseMethodDelegate(this.set_FirstNameProxyGetBaseMethod);     object[] arguments = new object[] { value };     IMethodInvocation<User<IRepository>> methodInvocation =         new MethodInvocation<User<IRepository>>(this, callBase, "set_FirstName", arguments, interceptors);          this.Interceptors[0].Handle(methodInvocation); } As you can see, a delegate instance is created which calls to a private method on the class, the private method calls the base method and would look like the following: calls base setter private void set_FirstNameProxyGetBaseMethod(string value) {     base.set_FirstName(value); } The delegate is invoked when methodInvocation.Continue() is called within an interceptor. The set_FirstName parameters are loaded into an object array. The current instance, delegate, method name and method arguments are passed into the methodInvocation constructor (there will be more data not illustrated here passed in when created including method info, return types, argument types etc.) The DefaultInterceptor’s Handle method is called with the methodInvocation instance as it’s parameter. Obviously methods can have return values, ref and out parameters etc. in these cases the generated method override body will be slightly different from above. I’ll go into more detail on these aspects as we build them. Conclusion I hope this has been useful, I can’t guarantee that the proxy will look exactly like the above, but at the moment, this is pretty much what I intend to do. Always worth downloading the code at http://rapidioc.codeplex.com/ to see the latest. There will also be some tests that you can debug through to help see what’s going on. Cheers, Sean.

• GZip/Deflate Compression in ASP.NET MVC

  - by Rick Strahl

  A long while back I wrote about GZip compression in ASP.NET. In that article I describe two generic helper methods that I've used in all sorts of ASP.NET application from WebForms apps to HttpModules and HttpHandlers that require gzip or deflate compression. The same static methods also work in ASP.NET MVC. Here are the two routines:/// <summary> /// Determines if GZip is supported /// </summary> /// <returns></returns> public static bool IsGZipSupported() { string AcceptEncoding = HttpContext.Current.Request.Headers["Accept-Encoding"]; if (!string.IsNullOrEmpty(AcceptEncoding) && (AcceptEncoding.Contains("gzip") || AcceptEncoding.Contains("deflate"))) return true; return false; } /// <summary> /// Sets up the current page or handler to use GZip through a Response.Filter /// IMPORTANT: /// You have to call this method before any output is generated! /// </summary> public static void GZipEncodePage() { HttpResponse Response = HttpContext.Current.Response; if (IsGZipSupported()) { string AcceptEncoding = HttpContext.Current.Request.Headers["Accept-Encoding"]; if (AcceptEncoding.Contains("gzip")) { Response.Filter = new System.IO.Compression.GZipStream(Response.Filter, System.IO.Compression.CompressionMode.Compress); Response.Headers.Remove("Content-Encoding"); Response.AppendHeader("Content-Encoding", "gzip"); } else { Response.Filter = new System.IO.Compression.DeflateStream(Response.Filter, System.IO.Compression.CompressionMode.Compress); Response.Headers.Remove("Content-Encoding"); Response.AppendHeader("Content-Encoding", "deflate"); } } // Allow proxy servers to cache encoded and unencoded versions separately Response.AppendHeader("Vary", "Content-Encoding"); } The first method checks whether the client sending the request includes the accept-encoding for either gzip or deflate, and if if it does it returns true. The second function uses IsGzipSupported() to decide whether it should encode content and uses an Response Filter to do its job. Basically response filters look at the Response output stream as it's written and convert the data flowing through it. Filters are a bit tricky to work with but the two .NET filter streams for GZip and Deflate Compression make this a snap to implement. In my old code and even now in MVC I can always do:public ActionResult List(string keyword=null, int category=0) { WebUtils.GZipEncodePage(); …} to encode my content. And that works just fine. The proper way: Create an ActionFilterAttribute However in MVC this sort of thing is typically better handled by an ActionFilter which can be applied with an attribute. So to be all prim and proper I created an CompressContentAttribute ActionFilter that incorporates those two helper methods and which looks like this:/// <summary> /// Attribute that can be added to controller methods to force content /// to be GZip encoded if the client supports it /// </summary> public class CompressContentAttribute : ActionFilterAttribute { /// <summary> /// Override to compress the content that is generated by /// an action method. /// </summary> /// <param name="filterContext"></param> public override void OnActionExecuting(ActionExecutingContext filterContext) { GZipEncodePage(); } /// <summary> /// Determines if GZip is supported /// </summary> /// <returns></returns> public static bool IsGZipSupported() { string AcceptEncoding = HttpContext.Current.Request.Headers["Accept-Encoding"]; if (!string.IsNullOrEmpty(AcceptEncoding) && (AcceptEncoding.Contains("gzip") || AcceptEncoding.Contains("deflate"))) return true; return false; } /// <summary> /// Sets up the current page or handler to use GZip through a Response.Filter /// IMPORTANT: /// You have to call this method before any output is generated! /// </summary> public static void GZipEncodePage() { HttpResponse Response = HttpContext.Current.Response; if (IsGZipSupported()) { string AcceptEncoding = HttpContext.Current.Request.Headers["Accept-Encoding"]; if (AcceptEncoding.Contains("gzip")) { Response.Filter = new System.IO.Compression.GZipStream(Response.Filter, System.IO.Compression.CompressionMode.Compress); Response.Headers.Remove("Content-Encoding"); Response.AppendHeader("Content-Encoding", "gzip"); } else { Response.Filter = new System.IO.Compression.DeflateStream(Response.Filter, System.IO.Compression.CompressionMode.Compress); Response.Headers.Remove("Content-Encoding"); Response.AppendHeader("Content-Encoding", "deflate"); } } // Allow proxy servers to cache encoded and unencoded versions separately Response.AppendHeader("Vary", "Content-Encoding"); } } It's basically the same code wrapped into an ActionFilter attribute, which intercepts requests MVC requests to Controller methods and lets you hook up logic before and after the methods have executed. Here I want to override OnActionExecuting() which fires before the Controller action is fired. With the CompressContentAttribute created, it can now be applied to either the controller as a whole:[CompressContent] public class ClassifiedsController : ClassifiedsBaseController { … } or to one of the Action methods:[CompressContent] public ActionResult List(string keyword=null, int category=0) { … } The former applies compression to every action method, while the latter is selective and only applies it to the individual action method. Is the attribute better than the static utility function? Not really, but it is the standard MVC way to hook up 'filter' content and that's where others are likely to expect to set options like this. In fact,  you have a bit more control with the utility function because you can conditionally apply it in code, but this is actually much less likely in MVC applications than old WebForms apps since controller methods tend to be more focused. Compression Caveats Http compression is very cool and pretty easy to implement in ASP.NET but you have to be careful with it - especially if your content might get transformed or redirected inside of ASP.NET. A good example, is if an error occurs and a compression filter is applied. ASP.NET errors don't clear the filter, but clear the Response headers which results in some nasty garbage because the compressed content now no longer matches the headers. Another issue is Caching, which has to account for all possible ways of compression and non-compression that the content is served. Basically compressed content and caching don't mix well. I wrote about several of these issues in an old blog post and I recommend you take a quick peek before diving into making every bit of output Gzip encoded. None of these are show stoppers, but you have to be aware of the issues.

• ASP.NET AJAX ToolkitScriptManager Issue With Combining Scripts

  - by Kumar

  I have an ASP.NET 3.5 web application in which i am using the ToolkitScriptManager as below: <ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" EnablePageMethods="true" ScriptMode="Release" LoadScriptsBeforeUI="false" runat="server" CombineScripts="false"> <CompositeScript> <Scripts> <asp:ScriptReference Path="~/JavaScript/jquery-1.4.1.min.js" /> <asp:ScriptReference Path="~/JavaScript/Validators.js" /> </Scripts> </CompositeScript> </ajaxToolkit:ToolkitScriptManager> This works fine but from a performance standpoint this is not good as the pages are making a lot of requests to the webresources.axd and scriptresource.axd files. When I changed the CombineScripts property to true my ASP.NET AJAX control extenders are no longer working. What is the reason for this weired behavior and is there a fix for this?

• Creating an ASP.NET report using Visual Studio 2010 - Part 1

  - by rajbk

  This tutorial walks you through creating an report based on the Northwind sample database. You will add a client report definition file (RDLC), create a dataset for the RDLC, define queries using LINQ to Entities, design the report and add a ReportViewer web control to render the report in a ASP.NET web page. The report will have a chart control. Different results will be generated by changing filter criteria. At the end of the walkthrough, you should have a UI like the following.  From the UI below, a user is able to view the product list and can see a chart with the sum of Unit price for a given category. They can filter by Category and Supplier. The drop downs will auto post back when the selection is changed.  This demo uses Visual Studio 2010 RTM. This post is split into three parts. The last part has the sample code attached. Creating an ASP.NET report using Visual Studio 2010 - Part 2 Creating an ASP.NET report using Visual Studio 2010 - Part 3   Lets start by creating a new ASP.NET empty web application called “NorthwindReports” Creating the Data Access Layer (DAL) Add a web form called index.aspx to the root directory. You do this by right clicking on the NorthwindReports web project and selecting “Add item..” . Create a folder called “DAL”. We will store all our data access methods and any data transfer objects in here.   Right click on the DAL folder and add a ADO.NET Entity data model called Northwind. Select “Generate from database” and click Next. Create a connection to your database containing the Northwind sample database and click Next.   From the table list, select Categories, Products and Suppliers and click next. Our Entity data model gets created and looks like this:    Adding data transfer objects Right click on the DAL folder and add a ProductViewModel. Add the following code. This class contains properties we need to render our report. public class ProductViewModel { public int? ProductID { get; set; } public string ProductName { get; set; } public System.Nullable<decimal> UnitPrice { get; set; } public string CategoryName { get; set; } public int? CategoryID { get; set; } public int? SupplierID { get; set; } public bool Discontinued { get; set; } } Add a SupplierViewModel class. This will be used to render the supplier DropDownlist. public class SupplierViewModel { public string CompanyName { get; set; } public int SupplierID { get; set; } } Add a CategoryViewModel class. public class CategoryViewModel { public string CategoryName { get; set; } public int CategoryID { get; set; } } Create an IProductRepository interface. This will contain the signatures of all the methods we need when accessing the entity model.  This step is not needed but follows the repository pattern. interface IProductRepository { IQueryable<Product> GetProducts(); IQueryable<ProductViewModel> GetProductsProjected(int? supplierID, int? categoryID); IQueryable<SupplierViewModel> GetSuppliers(); IQueryable<CategoryViewModel> GetCategories(); } Create a ProductRepository class that implements the IProductReposity above. The methods available in this class are as follows: GetProducts – returns an IQueryable of all products. GetProductsProjected – returns an IQueryable of ProductViewModel. The method filters all the products based on SupplierId and CategoryId if any. It then projects the result into the ProductViewModel. GetSuppliers() – returns an IQueryable of all suppliers projected into a SupplierViewModel GetCategories() – returns an IQueryable of all categories projected into a CategoryViewModel  public class ProductRepository : IProductRepository { /// <summary> /// IQueryable of all Products /// </summary> /// <returns></returns> public IQueryable<Product> GetProducts() { var dataContext = new NorthwindEntities(); var products = from p in dataContext.Products select p; return products; }   /// <summary> /// IQueryable of Projects projected /// into the ProductViewModel class /// </summary> /// <returns></returns> public IQueryable<ProductViewModel> GetProductsProjected(int? supplierID, int? categoryID) { var projectedProducts = from p in GetProducts() select new ProductViewModel { ProductID = p.ProductID, ProductName = p.ProductName, UnitPrice = p.UnitPrice, CategoryName = p.Category.CategoryName, CategoryID = p.CategoryID, SupplierID = p.SupplierID, Discontinued = p.Discontinued }; // Filter on SupplierID if (supplierID.HasValue) { projectedProducts = projectedProducts.Where(a => a.SupplierID == supplierID); }   // Filter on CategoryID if (categoryID.HasValue) { projectedProducts = projectedProducts.Where(a => a.CategoryID == categoryID); }   return projectedProducts; }     public IQueryable<SupplierViewModel> GetSuppliers() { var dataContext = new NorthwindEntities(); var suppliers = from s in dataContext.Suppliers select new SupplierViewModel { SupplierID = s.SupplierID, CompanyName = s.CompanyName }; return suppliers; }   public IQueryable<CategoryViewModel> GetCategories() { var dataContext = new NorthwindEntities(); var categories = from c in dataContext.Categories select new CategoryViewModel { CategoryID = c.CategoryID, CategoryName = c.CategoryName }; return categories; } } Your solution explorer should look like the following. Build your project and make sure you don’t get any errors. In the next part, we will see how to create the client report definition file using the Report Wizard.   Creating an ASP.NET report using Visual Studio 2010 - Part 2

• Setting up Metro 2.0 with Jetty 7

  - by trojanfoe

  This question relates to a previous question of mine. I am attempting to set-up a low overhead Web Container using Jetty 7 that I can deploy Web Services using Metro 2.0. I have installed the following Metro 2.0 libs into jetty/lib: webservices-extra-api.jar webservices-extra.jar webservices-rt.jar webservices-tools.jar And the following into a new jetty/lib/endorsed directory: jsr173_api.jar webservices-api.jar I start Jetty with the following script (Windows) to ensure that jetty/lib/endorsed is part of the 'endorsed library path' and to ensure that Jetty adds the webservices jars to its classpath: @echo off set JETTY_HOME=C:\dev\jetty-7.1.0 set JAVA_OPTS=-Xmx1024m -XX:MaxPermSize=512m -Djetty.home=%JETTY_HOME% -Djava.endorsed.dirs=%JETTY_HOME%\lib\endorsed -Djetty.class.path=%JETTY_HOME%\lib\webservices-rt.jar;%JETTY_HOME%\lib\endorsed\webservices-api.jar -DSTOP.PORT=8079 -DSTOP.KEY=jettykey pushd %JETTY_HOME% java %JAVA_OPTS% -jar start.jar popd However when I deploy a WebServices war file (for example Metro sample 'pricequote'), I get the following exception: java.lang.ClassNotFoundException: com.sun.xml.ws.transport.http.servlet.WSServletContextListener Can anyone help me with this please? I suspect it's related to the order of classes in Jetty's classpath?

• How to get MSBuild Exec to run a java program?

  - by Vaccano

  I am trying to run a command line action in my Team Build (MSBuild). When I run it on the command line of the build machine it works fine. But when run in the build script I get a "exited with code 3". This is command that I am running: C:\Program Files\Wavelink\Avalanche\PackageBuilder.\jresdk\bin\java -classpath "WLUtil.jar;WLPackageBuilder.jar" com.wavelink.buildpkg.AvalanchePackageBuilder /build PackageName This command only works when run from the above directory (I have tried running it from c:\ with the full path at it fails). When I try to run it using ms build this is my statement: <PropertyGroup> <!--Working directory of the Package Builder Call--> <PkgBldWorkingDir>&quot;C:\Program Files\Wavelink\Avalanche\PackageBuilder&quot;</PkgBldWorkingDir> <!--Command line to run to make Package builder "go"--> <PkgBldRun>.\jresdk\bin\java&quot; -classpath &quot;WLUtil.jar;WLPackageBuilder.jar&quot; com.wavelink.buildpkg.AvalanchePackageBuilder</PkgBldRun> </PropertyGroup> <!--Run package builder command line to update the Ava File.--> <Exec ContinueOnError="true" WorkingDirectory="$(PackageBuilderWorkingDir)" Command="$(PkgBldRun) /build PackageName"/> As I said above this "exits with code 3". This is the full output: Task "Exec" Command: .\jresdk\bin\java -classpath "WLUtil.jar;WLPackageBuilder.jar" com.wavelink.buildpkg.AvalanchePackageBuilder /build PackageName The system cannot find the path specified. MSBUILD : warning MSB3073: The command ".\jresdk\bin\java -classpath "WLUtil.jar;WLPackageBuilder.jar" com.wavelink.buildpkg.AvalanchePackageBuilder /build PackageName" exited with code 3. The previous error was converted to a warning because the task was called with ContinueOnError=true. Build continuing because "ContinueOnError" on the task "Exec" is set to "true". Done executing task "Exec" -- FAILED. It says it can't find the file (who knows what file). I have tried it with and without the quotes (") in the working directory and with a full path as the command (gives the same error as when run on the command line). Any ideas on how to make this run a command line action in MS Build?

• MvcExtensions – Bootstrapping

  - by kazimanzurrashid

  When you create a new ASP.NET MVC application you will find that the global.asax contains the following lines: namespace MvcApplication1 { // Note: For instructions on enabling IIS6 or IIS7 classic mode, // visit http://go.microsoft.com/?LinkId=9394801 public class MvcApplication : System.Web.HttpApplication { public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults ); } protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); } } } As the application grows, there are quite a lot of plumbing code gets into the global.asax which quickly becomes a design smell. Lets take a quick look at the code of one of the open source project that I recently visited: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute("Default","{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" }); } protected override void OnApplicationStarted() { Error += OnError; EndRequest += OnEndRequest; var settings = new SparkSettings() .AddNamespace("System") .AddNamespace("System.Collections.Generic") .AddNamespace("System.Web.Mvc") .AddNamespace("System.Web.Mvc.Html") .AddNamespace("MvcContrib.FluentHtml") .AddNamespace("********") .AddNamespace("********.Web") .SetPageBaseType("ApplicationViewPage") .SetAutomaticEncoding(true); #if DEBUG settings.SetDebug(true); #endif var viewFactory = new SparkViewFactory(settings); ViewEngines.Engines.Add(viewFactory); #if !DEBUG PrecompileViews(viewFactory); #endif RegisterAllControllersIn("********.Web"); log4net.Config.XmlConfigurator.Configure(); RegisterRoutes(RouteTable.Routes); Factory.Load(new Components.WebDependencies()); ModelBinders.Binders.DefaultBinder = new Binders.GenericBinderResolver(Factory.TryGet<IModelBinder>); ValidatorConfiguration.Initialize("********"); HtmlValidationExtensions.Initialize(ValidatorConfiguration.Rules); } private void OnEndRequest(object sender, System.EventArgs e) { if (((HttpApplication)sender).Context.Handler is MvcHandler) { CreateKernel().Get<ISessionSource>().Close(); } } private void OnError(object sender, System.EventArgs e) { CreateKernel().Get<ISessionSource>().Close(); } protected override IKernel CreateKernel() { return Factory.Kernel; } private static void PrecompileViews(SparkViewFactory viewFactory) { var batch = new SparkBatchDescriptor(); batch.For<HomeController>().For<ManageController>(); viewFactory.Precompile(batch); } As you can see there are quite a few of things going on in the above code, Registering the ViewEngine, Compiling the Views, Registering the Routes/Controllers/Model Binders, Settings up Logger, Validations and as you can imagine the more it becomes complex the more things will get added in the application start. One of the goal of the MVCExtensions is to reduce the above design smell. Instead of writing all the plumbing code in the application start, it contains BootstrapperTask to register individual services. Out of the box, it contains BootstrapperTask to register Controllers, Controller Factory, Action Invoker, Action Filters, Model Binders, Model Metadata/Validation Providers, ValueProvideraFactory, ViewEngines etc and it is intelligent enough to automatically detect the above types and register into the ASP.NET MVC Framework. Other than the built-in tasks you can create your own custom task which will be automatically executed when the application starts. When the BootstrapperTasks are in action you will find the global.asax pretty much clean like the following: public class MvcApplication : UnityMvcApplication { public void ErrorLog_Filtering(object sender, ExceptionFilterEventArgs e) { Check.Argument.IsNotNull(e, "e"); HttpException exception = e.Exception.GetBaseException() as HttpException; if ((exception != null) && (exception.GetHttpCode() == (int)HttpStatusCode.NotFound)) { e.Dismiss(); } } } The above code is taken from my another open source project Shrinkr, as you can see the global.asax is longer cluttered with any plumbing code. One special thing you have noticed that it is inherited from the UnityMvcApplication rather than regular HttpApplication. There are separate version of this class for each IoC Container like NinjectMvcApplication, StructureMapMvcApplication etc. Other than executing the built-in tasks, the Shrinkr also has few custom tasks which gets executed when the application starts. For example, when the application starts, we want to ensure that the default users (which is specified in the web.config) are created. The following is the custom task that is used to create those default users: public class CreateDefaultUsers : BootstrapperTask { protected override TaskContinuation ExecuteCore(IServiceLocator serviceLocator) { IUserRepository userRepository = serviceLocator.GetInstance<IUserRepository>(); IUnitOfWork unitOfWork = serviceLocator.GetInstance<IUnitOfWork>(); IEnumerable<User> users = serviceLocator.GetInstance<Settings>().DefaultUsers; bool shouldCommit = false; foreach (User user in users) { if (userRepository.GetByName(user.Name) == null) { user.AllowApiAccess(ApiSetting.InfiniteLimit); userRepository.Add(user); shouldCommit = true; } } if (shouldCommit) { unitOfWork.Commit(); } return TaskContinuation.Continue; } } There are several other Tasks in the Shrinkr that we are also using which you will find in that project. To create a custom bootstrapping task you have create a new class which either implements the IBootstrapperTask interface or inherits from the abstract BootstrapperTask class, I would recommend to start with the BootstrapperTask as it already has the required code that you have to write in case if you choose the IBootstrapperTask interface. As you can see in the above code we are overriding the ExecuteCore to create the default users, the MVCExtensions is responsible for populating the  ServiceLocator prior calling this method and in this method we are using the service locator to get the dependencies that are required to create the users (I will cover the custom dependencies registration in the next post). Once the users are created, we are returning a special enum, TaskContinuation as the return value, the TaskContinuation can have three values Continue (default), Skip and Break. The reason behind of having this enum is, in some  special cases you might want to skip the next task in the chain or break the complete chain depending upon the currently running task, in those cases you will use the other two values instead of the Continue. The last thing I want to cover in the bootstrapping task is the Order. By default all the built-in tasks as well as newly created task order is set to the DefaultOrder(a static property), in some special cases you might want to execute it before/after all the other tasks, in those cases you will assign the Order in the Task constructor. For Example, in Shrinkr, we want to run few background services when the all the tasks are executed, so we assigned the order as DefaultOrder + 1. Here is the code of that Task: public class ConfigureBackgroundServices : BootstrapperTask { private IEnumerable<IBackgroundService> backgroundServices; public ConfigureBackgroundServices() { Order = DefaultOrder + 1; } protected override TaskContinuation ExecuteCore(IServiceLocator serviceLocator) { backgroundServices = serviceLocator.GetAllInstances<IBackgroundService>().ToList(); backgroundServices.Each(service => service.Start()); return TaskContinuation.Continue; } protected override void DisposeCore() { backgroundServices.Each(service => service.Stop()); } } That’s it for today, in the next post I will cover the custom service registration, so stay tuned.

  Hi Experts, I have problems with bindings. I want to use a UserControl (Intellibox from codeplex) but I only get error messages in the output window. Basically I have window grid ... stuff ... usercontrol (self written) ... stuff ... usercontrol (IntelliBox) In the Output window I get following stuff: System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.UserControl', AncestorLevel='1''. BindingExpression:Path=ShowResults; DataItem=null; target element is 'Popup' (Name='IntelliboxPopup1'); target property is 'IsOpen' (type 'Boolean') The binding in the IntelliBox control is defined as follows: {Binding Path=ShowResults, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}} I guess there is a problem, cause the nesting withing usercontrols - how to I get this error fixed? Thanks!

  I wonder if there is a way of concating two strings in Silverlight inside xaml file. I have a DataGrid where one of the columns is 'Default Contact' and I would like to represent data in there as first and last name. <sdk:DataGridTextColumn Header="Default Contact" Binding="{Binding Path=DefaultContact.FirstName}" /> I was thinking about something like: Binding="{Binding Path=DefaultContact.FirstName + " " + DefaultContact.LasttName}" But this doesn't work. I don't even know if this is possible to achieve. Seems like really basic thing so I hope it is supported in some way. Any help would be greatly appreciated.

In a perfect world the user would tap a date and below the datepicker html output would give the user specific times for the selected date instead of my last project of an image. my probelm is nothing is loading, so my question is what am i doing wrong? my code is as follows <!DOCTYPE html> <link type="text/css" href="css/ui-darkness/jquery-ui-1.8.custom.css" rel="stylesheet" /> <script type="text/javascript" src="js/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="js/jquery-ui-1.8.custom.min.js"></script> <script type="text/javascript"> $(function(){ // Datepicker $('#datepicker').datepicker({ dateFormat: 'yy-mm-dd', inline: true, minDate: new Date(2010, 1 - 1, 1), maxDate:new Date(2010, 12 - 1, 31), altField: '#datepicker_value', onSelect: function(){ var day1 = $("#datepicker").datepicker('getDate').getDate(); var month1 = $("#datepicker").datepicker('getDate').getMonth() + 1; var year1 = $("#datepicker").datepicker('getDate').getFullYear(); var fullDate = year1 + "" + month1 + "" + day1; //var str_output ="<img src=\"http://69.89.20.27/images/a" + fullDate +".png\" width=\"100%\"/>"; //"<h1>"+fullDate+"</h1>"; //"<img src=\"http://69.*.*.*/images/a" + fullDate +".png\"/>"; //$('#page_output').html(str_output); var doc = loadXMLDoc('date.xml'); // loading the XML file var el = doc.getElementsByTagName('_'+date); // retrieving the elements corrsponding to a date, eg: _20100103 var page_output = document.getElementById('page_output'); if(el.length >= 1) { // matched XML data found for the specified date var dt = el[0].getElementsByTagName('date'); var great_times = el[0].getElementsByTagName('great_times'); var good_times = el[0].getElementsByTagName('good_times'); var str_output = "<h1><center>" + dt[0].childNodes[0].nodeValue + "</center></h1><br/><br>"; str_output += "<b>Excellent Times:</b><br> " + great_times[0].childNodes[0].nodeValue + "<br/><br>"; str_output += "<b>Good Times:</b><br> " + good_times[0].childNodes[0].nodeValue + "<br/><br>"; $('#page_output').html(str_output);// writing the results to the div element (page_out) } else { alert("Sorry","Action not allowed on this page"); page_output.innerHTML = ''; // No XML data found for the selected date reloadmainwDate(); return false; } return true; } }); //hover states on the static widgets $('#dialog_link, ul#icons li').hover( function() { $(this).addClass('ui-state-hover'); }, function() { $(this).removeClass('ui-state-hover'); } ); }); //var img_date = .datepicker('getDate'); //var day1 = $("#datepicker").datepicker('getDate').getDate(); //var month1 = $("#datepicker").datepicker('getDate').getMonth() + 1; //var year1 = $("#datepicker").datepicker('getDate').getFullYear(); //var fullDate = year1 + "-" + month1 + "-" + day1; //var date = $('#datepicker').datepicker({ dateFormat: 'dd-mm-yy' }); //var str_output = "<h1><center><p>"+ date + "</p></center></h1>"; //$('#page_output')[0].innerHTML = str_output; // writing the results to the div element (page_out) </script> <script> function loadXMLDoc(dname) { var xmlDoc; // IE 5 and IE 6 if(typeof ActiveXObject != 'undefined') { xmlDoc=new ActiveXObject("Microsoft.XMLDOM"); xmlDoc.async=false; xmlDoc.load(dname); return xmlDoc; } else if (window.XMLHttpRequest) // firefox { xmlDoc=new window.XMLHttpRequest(); xmlDoc.open("GET",dname,false); xmlDoc.send(""); return xmlDoc.responseXML; } alert("Error loading document"); return null; } <!-- Datepicker --> <div id="datepicker"></div> <!-- Highlight / Error --> <div id="page_output"></div> </body>

• Silverlight RelativeSource of TemplatedParent Binding within a DataTemplate, Is it possible?

  - by Matt.M

  I'm trying to make a bar graph Usercontrol. I'm creating each bar using a DataTemplate. The problem is in order to compute the height of each bar, I first need to know the height of its container (the TemplatedParent). Unfortunately what I have: Height="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Height, Converter={StaticResource HeightConverter}, Mode=OneWay}" Does not work. Each time a value of NaN is returned to my Converter. Does RelativeSource={RelativeSource TemplatedParent} not work in this context? What else can I do to allow my DataTemplate to "talk" to the element it is being applied to? Incase it helps here is the barebones DataTemplate: <DataTemplate x:Key="BarGraphTemplate"> <Grid Width="30"> <Rectangle HorizontalAlignment="Center" Stroke="Black" Width="20" Height="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Height, Converter={StaticResource HeightConverter}, Mode=OneWay}" VerticalAlignment="Bottom" /> </Grid> </DataTemplate>

• Android Actionbar Tabs + Fragments + Service

  - by Vladimir

  So, I have 3 problems with my code: 1) I want that each tab saves its state. So that a TextView shows changed text if it was changed. 2) if I go to Tab2 then to Tab1 I can't see the content of the fragments.

• ASP.NET MVC Checkbox Group

  - by Greg Ogle

  I am trying to formulate a work-around for the lack of a "checkbox group" in ASP.NET MVC. The typical way to implement this is to have check boxes of the same name, each with the value it represents. <input type="checkbox" name="n" value=1 /> <input type="checkbox" name="n" value=2 /> <input type="checkbox" name="n" value=3 /> When submitted, it will comma delimit all values to the request item "n".. so Request["n"] == "1,2,3" if all three are checked when submitted. In ASP.NET MVC, you can have a parameter of n as an array to accept this post. public ActionResult ActionName( int[] n ) { ... } All of the above works fine. The problem I have is that when validation fails, the check boxes are not restored to their checked state. Any suggestions. Problem Code: (I started with the default asp.net mvc project) Controller public class HomeController : Controller { public ActionResult Index() { var t = getTestModel("First"); return View(t); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Index(TestModelView t) { if(String.IsNullOrEmpty( t.TextBoxValue)) ModelState.AddModelError("TextBoxValue", "TextBoxValue required."); var newView = getTestModel("Next"); return View(newView); } private TestModelView getTestModel(string prefix) { var t = new TestModelView(); t.Checkboxes = new List<CheckboxInfo>() { new CheckboxInfo(){Text = prefix + "1", Value="1", IsChecked=false}, new CheckboxInfo(){Text = prefix + "2", Value="2", IsChecked=false} }; return t; } } public class TestModelView { public string TextBoxValue { get; set; } public List<CheckboxInfo> Checkboxes { get; set; } } public class CheckboxInfo { public string Text { get; set; } public string Value { get; set; } public bool IsChecked { get; set; } } } ASPX <% using( Html.BeginForm() ){ %> <p><%= Html.ValidationSummary() %></p> <p><%= Html.TextBox("TextBoxValue")%></p> <p><% int i = 0; foreach (var cb in Model.Checkboxes) { %> <input type="checkbox" name="Checkboxes[<%=i%>]" value="<%= Html.Encode(cb.Value) %>" <%=cb.IsChecked ? "checked=\"checked\"" : String.Empty %> /><%= Html.Encode(cb.Text)%><br /> <% i++; } %></p> <p><input type="submit" value="submit" /></p> <% } %> Working Code Controller [AcceptVerbs(HttpVerbs.Post)] public ActionResult Index(TestModelView t) { if(String.IsNullOrEmpty( t.TextBoxValue)) { ModelState.AddModelError("TextBoxValue", "TextBoxValue required."); return View(t); } var newView = getTestModel("Next"); return View(newView); } ASPX int i = 0; foreach (var cb in Model.Checkboxes) { %> <input type="checkbox" name="Checkboxes[<%=i%>].IsChecked" <%=cb.IsChecked ? "checked=\"checked\"" : String.Empty %> value="true" /> <input type="hidden" name="Checkboxes[<%=i%>].IsChecked" value="false" /> <input type="hidden" name="Checkboxes[<%=i%>].Value" value="<%= cb.Value %>" /> <input type="hidden" name="Checkboxes[<%=i%>].Text" value="<%= cb.Text %>" /> <%= Html.Encode(cb.Text)%><br /> <% i++; } %></p> <p><input type="submit" value="submit" /></p> Of course something similar could be done with Html Helpers, but this works.

• sqllite and populating list view, android

  I am populating a text and list view from a sqllite database.

• Seriously, what's the deal with InheritInChildApplications? Does this work for anyone??

  - by mare

  I've tried wrapping my <system.web> with <location path="." InheritInChildApplications="false"> like this <location path="." InheritInChildApplications="false"> <system.web>...</system.web> </location> But VS 2010 Web Developer Express keeps saying "The 'InheritInChildApplications' attribute is not allowed" and when I run my web app there's an error: "HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid." Config Error Unrecognized attribute 'InheritInChildApplications'. I've seen some smartguys all over the Internet discussing this and how it is working for them but there's much larger number of people here at SO and other places that did not get this to work. My configuration: ASP.NET 4.0 RTM, VS 2010, IIS 7.5

• Using Image Source with big images in WPF

  - by xyzzer

  I am working on an application that allows users to manipulate multiple images by using ItemsControl. I started running some tests and found that the app has problems displaying some big images - ie. it did not work with the high resolution (21600x10800), 20MB images from http://earthobservatory.nasa.gov/Features/BlueMarble/BlueMarble_monthlies.php, though it displays the 6200x6200, 60MB Hubble telescope image from http://zebu.uoregon.edu/hudf/hudf.jpg just fine. The original solution just specified an Image control with a Source property pointing at a file on a disk (through a binding). With the Blue Marble file - the image would just not show up. Now this could be just a bug hidden somewhere deep in the funky MVVM + XAML implementation - the visual tree displayed by Snoop goes like: Window/Border/AdornerDecorator/ContentPresenter/Grid/Canvas/UserControl/Border/ContentPresenter/Grid/Grid/Grid/Grid/Border/Grid/ContentPresenter/UserControl/UserControl/Border/ContentPresenter/Grid/Grid/Grid/Grid/Viewbox/ContainerVisual/UserControl/Border/ContentPresenter/Grid/Grid/ItemsControl/Border/ItemsPresenter/Canvas/ContentPresenter/Grid/Grid/ContentPresenter/Image... Now debug this! WPF can be crazy like that... Anyway, it turned out that if I create a simple WPF application - the images load just fine. I tried finding out the root cause, but I don't want to spend weeks on it. I figured the right thing to do might be to use a converter to scale the images down - this is what I have done: ImagePath = @"F:\Astronomical\world.200402.3x21600x10800.jpg"; TargetWidth = 2800; TargetHeight = 1866; and <Image> <Image.Source> <MultiBinding Converter="{StaticResource imageResizingConverter}"> <MultiBinding.Bindings> <Binding Path="ImagePath"/> <Binding RelativeSource="{RelativeSource Self}" /> <Binding Path="TargetWidth"/> <Binding Path="TargetHeight"/> </MultiBinding.Bindings> </MultiBinding> </Image.Source> </Image> and public class ImageResizingConverter : MarkupExtension, IMultiValueConverter { public Image TargetImage { get; set; } public string SourcePath { get; set; } public int DecodeWidth { get; set; } public int DecodeHeight { get; set; } public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture) { this.SourcePath = values[0].ToString(); this.TargetImage = (Image)values[1]; this.DecodeWidth = (int)values[2]; this.DecodeHeight = (int)values[3]; return DecodeImage(); } private BitmapImage DecodeImage() { BitmapImage bi = new BitmapImage(); bi.BeginInit(); bi.DecodePixelWidth = (int)DecodeWidth; bi.DecodePixelHeight = (int)DecodeHeight; bi.UriSource = new Uri(SourcePath); bi.EndInit(); return bi; } public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture) { throw new Exception("The method or operation is not implemented."); } public override object ProvideValue(IServiceProvider serviceProvider) { return this; } } Now this works fine, except for one "little" problem. When you just specify a file path in Image.Source - the application actually uses less memory and works faster than if you use BitmapImage.DecodePixelWidth. Plus with Image.Source if you have multiple Image controls that point to the same image - they only use as much memory as if only one image was loaded. With the BitmapImage.DecodePixelWidth solution - each additional Image control uses more memory and each of them uses more than when just specifying Image.Source. Perhaps WPF somehow caches these images in compressed form while if you specify the decoded dimensions - it feels like you get an uncompressed image in memory, plus it takes 6 times the time (perhaps without it the scaling is done on the GPU?), plus it feels like the original high resolution image also gets loaded and takes up space. If I just scale the image down, save it to a temporary file and then use Image.Source to point at the file - it will probably work, but it will be pretty slow and it will require handling cleanup of the temporary file. If I could detect an image that does not get loaded properly - maybe I could only scale it down if I need to, but Image.ImageFailed never gets triggered. Maybe it has something to do with the video memory and this app just using more of it with the deep visual tree, opacity masks etc. Actual question: How can I load big images as quickly as Image.Source option does it, without using more memory for additional copies and additional memory for the scaled down image if I only need them at a certain resolution lower than original? Also, I don't want to keep them in memory if no Image control is using them anymore.

• How can I Diff a Svn Repository using SharpSvn

  - by AngeDeLaMort

  Hello, My question is quite simple and with the SharpSvn Api, it should be easy as well. Here what I did: path = "c:\project"; using (SvnLookClient client = new SvnLookClient()) { SvnLookOrigin o = new SvnLookOrigin(path); Collection<SvnChangedEventArgs> changeList; client.GetChanged(o, out changeList); // <-- Exception } and when I call the GetChanged, I get an exception: Can't open file 'c:\project\format': The system cannot find the file specified. So, Maybe there is something I'm missing? Or maybe it's not the right way to do find out the list of files and folders that were modified in the local repository? Thanks in advance.
