  • How do I configure StructureMap to use a generic repository?

    - by simonjreid
    I have an interface IGenericRepository<TEntity> where TEntity : IEntity and an implementation GenericRepository<TEntity> where TEntity : Entity. I'm trying to inject a specific IGenericRepository<Section> into a class using StructureMap: ObjectFactory.Initialize(x => { x.For(typeof(IGenericRepository<>)).Use(typeof(GenericRepository<>)); }); But when I try to use ObjectFactory.GetInstance<IGenericRepository<Section>>(); I get: StructureMap Exception Code: 202 No Default Instance defined for PluginFamily System.Data.Common.DbConnection Any ideas why this is or what I'm doing wrong? Thanks in advance, Simon

  • What is the proper way to access datastore in custom Model Binders?

    - by mare
    How should I properly implement data access in my custom model binders? Like in controllers I use IContentRepository and then have it create an instance of its implementing class in constructor. So I have everything ready for incorporating IoC (DI) at a later stage. Now I need something similar in model binder. I need to make some DB lookups in the binder. I'm thinking of doing it the same way I do it in controllers but I am open to suggestion. This is a snippet from one of my controllers so you can imagine how I'm doing it in them: public class WidgetZoneController : BaseController { // BaseController has IContentRepository ContentRepository field public WidgetZoneController() : this(new XmlWidgetZoneRepository()) { } public WidgetZoneController(IContentRepository repository) { ContentRepository = repository; } ...

  • Unable to step into interface implementation configured by unity application block

    - by Rahul
    I have configured a set of interface implementations with EntLib. unity block. The constructor of implementation classes work fine as soon as I run the application: 1. The interface to implement when I run the application the cctor runs fine, which shows that unity resolution was successful: But when I try to call a method of this class, the code just passes through without actually invoking the function of the implemented class: Edit: Added on June 11, 2012 Following is the Unity Configuration I have. (This is all the unity configuration I am doing) public class UnityControllerFactory : DefaultControllerFactory { private static readonly IUnityContainer container; private static UnityControllerFactory factory = null; static UnityControllerFactory() { container = new UnityContainer(); UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity"); section.Configure(container); factory = new UnityControllerFactory(); } public static UnityControllerFactory GetControllerFactory() { return factory; } protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { return container.Resolve(controllerType) as IController; } } I am unable to step into this code and the implementation simply skips out without executing anything. What is wrong here?

  • How can I pass methods in javascript?

    - by peterjwest
    I often need to pass methods from objects into other objects. However I usually want the method to be attached to the original object (by attached I mean 'this' should refer to the original object). I know a few ways to do this: a) In the object constructor: ObjectA = function() { var that = this; var method = function(a,b,c) { that.abc = a+b+c }} b) In objectA which has been passed objectB: objectB.assign(function(a,b,c) { that.method(a,b,c) }) c) Outside both objects: objectB.assign(function(a,b,c) { objectA.method(a,b,c) }) I want to know if there is a simpler way to pass methods attached to their original objects.

  • Hibernate session method to update object

    - by EugeneP
    I need this roadmap of a Hibernate managed object instance. First, I create an instance with initial properties and persist this object in a db. Then session associated with this object is closed. But still, I serialize my object and on the next step deserialize it, invoke some setters, and again, I need to update what changed in a database. What methods of Hibernate session should I use? persist() or save() on the first step and saveOrUpdate() on the second? In fact I see that saveOrUpdate() can be used on each step. What would you recommend?

  • Dynamic domain methods missing from grails service when injected into java service in grails app.

    - by Gordon C
    I had the idea that I would write my GroovyDao as a grails service. Next I would write a MyJavaService in java and locate it in the java sources dir in my grails app. MyJavaService contains a instance reference to groovyDao for spring injection. I would wire up in resources.groovy the MyJavaService with a groovyDao = ref("GroovyDao"). Everything starts up fine. However if I make call to MyJavaService any Domain method like Domain.list() returns a Method not found error. Any help is appreciated.

  • If the dependency is a unique snapshot version and install is called, what does maven select?

    - by chrsk
    Imagine two projects. The first is the framework-core project which is in version 1.1.0 and has several snapshot builds. The other is the example-business project which has the following dependency to framework-core on the build-iteration number 9. <dependency> <groupId>org.example</groupId> <artifactId>framework-core</artifactId> <version>1.1.0-20100518.134928-9</version> </dependency> What happens if mvn install is called on the framework-core? I found out that the artifact is copied to the folder and is named to *.1.1.0-SNAPSHOT.jar (as expected). This lead me to the assumption that this version is only used if even this 1.1.0-SNAPSHOT version is defined as dependency and not the precise build. To test something local without deploying it to the maven repository: call mvn install, change the dependency to 1.1.0-SNAPSHOT -- and the artifact just installed is used? Or is it possible to overwrite the specific build (with using the install lifecycle phase)?

  • Custom SessionListener, name is not bound in this context, javax.naming.NameNotFoundException

    - by mehmet6parmak
    Hi, I am trying to implement HttpSessionListener so that users of this listener can register implementation of ISessionEvent interface to session Events.code is below: public class MySessionListener implements HttpSessionListener{ @Resource ISessionEvent sessionEvent; public ISessionEvent getSessionEvent() { return sessionEvent; } public void setSessionEvent(ISessionEvent sessionEvent) { this.sessionEvent = sessionEvent; } @Override public void sessionCreated(HttpSessionEvent arg0) { sessionEvent.SessionCreated(arg0.getSession()); } @Override public void sessionDestroyed(HttpSessionEvent arg0) { sessionEvent.SessionDestroyed(arg0.getSession()); } } When user implement ISessionEvent and add as a bean, SessionCreated and SessionDestroyed functions of implementation will be called when these events occured. You can ask why dont you just write inside listeners methods, i dont i'm just trying. When i try the code above i got the following error message: javax.naming.NameNotFoundException: Name com.mehmet6parmak.sessionlistener.MySessionListener is not bound in this Context at org.apache.naming.NamingContext.lookup(NamingContext.java:770) at org.apache.naming.NamingContext.lookup(NamingContext.java:153) at org.apache.catalina.util.DefaultAnnotationProcessor.lookupFieldResource(DefaultAnnotationProcessor.java:278) at org.apache.catalina.util.DefaultAnnotationProcessor.processAnnotations(DefaultAnnotationProcessor.java:187) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4082) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4630) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardHost.start(StandardHost.java:785) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:445) at org.apache.catalina.core.StandardService.start(StandardService.java:519) at org.apache.catalina.core.StandardServer.start(StandardServer.java:710) at org.apache.catalina.startup.Catalina.start(Catalina.java:581) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:289) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:414) Resource annotation causes the error but i could not resolve it.

  • Best way to order menu items injected by an IoC/plugin Framework

    - by Daver
    One of the common things I've seen done in applications built on IoC/plugin frameworks is to add commands to menus or toolbars from the dynamically loaded plugins. For example, the application's default plugins supply actions like "New, Open, Save" that show up in the context menu for a certain item in the workspace. A new plugin may add "Mail, Post, Encrypt" commands, but where do those commands show up in relation to "New, Open, Save"? How can the application that is loading components through IoC impose order on the items that get injected? Does it require metadata from the plugins that give a hint on how to group or order the items? Does it use a config file of previously known menu names (or ids) to define the order (seems a little weak to me)? Or are "unknown" plugins treated as second class citizens and always get dumped into sub menus? Something I've never even imagined (which I'm hoping to see in the answers)

  • Dynamically create and cast objects at runtime

    - by vaibhav bindroo
    Let's say we have 2 classes A and B public class A{ private int member1; A() { member1 = 10; } public getMember(){ return member1; } } Class B is also on the same lines except that its member variable is named member2 and gets intitialized to say 20 inside the constructor. My Requirement : At runtime , I get a string which contains a className ( could be A or B). I want to dynamically create an object of this class along with invoking the constructor. How can I achieve this . I don't want to use interfaces for common functionality of above classes Morever, later on I set the properties of this raw object using Propery Builder Bean Util class based on a list of columns . Class clazz = Class.forName("className"); Obj obj = clazz.newInstance(); How I can dynamically convert that obj to className object.

  • PHP object class variable

    - by mck89
    I have built a class in PHP and I must declare a class variable as an object. Everytime I want to declare an empty object I use: $var=new stdClass; But if I use it to declare a class variable as class foo { var $bar=new stdClass; } a parse error occurs. Is there a way to do this or must I declare the class variable as an object in the constructor function? PS: I'm using PHP 4.

  • Comparing all properties of an object using expression trees

    - by stringargs
    Hi, I'm trying to write a simple generator that uses an expression tree to dynamically generate a method that compares all properties of an instance of a type to the properties of another instance of that type. This works fine for most properties, like int an string, but fails for DateTime? (and presumably other nullable value types). The method: static Delegate GenerateComparer(Type type) { var left = Expression.Parameter(type, "left"); var right = Expression.Parameter(type, "right"); Expression result = null; foreach (var p in type.GetProperties()) { var leftProperty = Expression.Property(left, p.Name); var rightProperty = Expression.Property(right, p.Name); var equals = p.PropertyType.GetMethod("Equals", new[] { p.PropertyType }); var callEqualsOnLeft = Expression.Call(leftProperty, equals, rightProperty); result = result != null ? (Expression)Expression.And(result, callEqualsOnLeft) : (Expression)callEqualsOnLeft; } var method = Expression.Lambda(result, left, right).Compile(); return method; } On a DateTime? property it fails with: Expression of type 'System.Nullable`1[System.DateTime]' cannot be used for parameter of type 'System.Object' of method 'Boolean Equals(System.Object)' OK, so it finds an overload of Equals that expects object. So why can't I pass a DateTime? into that, as it's convertible to object? If I look at Nullable<T>, it indeed has an override of Equals(object o). PS: I realize that this isn't a proper generator yet as it can't deal with null values, but I'll get to that :)

  • Unity: Replace registered type with another type at runtime

    - by gehho
    We have a scenario where the user can choose between different hardware at runtime. In the background we have several different hardware classes which all implement an IHardware interface. We would like to use Unity to register the currently selected hardware instance for this interface. However, when the user selects another hardware, this would require us to replace this registration at runtime. The following example might make this clearer: public interface IHardware { // some methods... } public class HardwareA : IHardware { // ... } public class HardwareB : IHardware { // ... } container.RegisterInstance<IHardware>(new HardwareA()); // user selects new hardware somewhere in the configuration... // the following is invalid code, but can it be achieved another way? container.ReplaceInstance<IHardware>(new HardwareB()); Can this behavior be achieved somehow? BTW: I am completely aware that instances which have already been resolved from the container will not be replaced with the new instances, of course. We would take care of that ourselves by forcing them to resolve the instance once again.
