    Error while using remoting with Home objects?

    Christopher no Newbie

      Hi,

      I have the following code:

      /*TestAction.java*/
      @Stateless
      @Name("testAction")
      public class TestAction extends EntityHome<Category> implements TestActionInterface{
      
       public String testName(String name){
       return "Hello, "+name;
       }
      
       @Remove
       public void destroy(){}
      }
      
      
      /*TestActionInterface.java*/
      
      @Local
      public interface TestActionInterface {
       @WebRemote
       public String testName(String name);
      
       @WebRemote
       @Remove
       public void destroy();
      }
      
      /*testfunctions.js*/
      
      function callAjax(name){
      
       Seam.Remoting.setDebug(true);
      
       Seam.Component.newInstance('testAction').testName(name, sayHaloCallback);
      
      };
      
      function sayHaloCallback(result){
       alert(result);
      
      }
      
      


      And it works fine. But I need to invoke a method from the Home object, so I uncomment "extends EntityHome".
      In this case I get the following error:

      ERROR [ContextualHttpServletRequest] ended request due to exception

      What am I doing wrong and how can I invoke method from Home object using remoting mechanism?

      And the next question is why Home objects can't be @Stateless? When I change @Stateful annotation (in TestAction.java) into @Stateless I get the following error:

          Sorry, the fragment in TestAcion.java

          extends EntityHome<Category>
          is initially commented! Then works fine. And when it's uncommented it causes errors as described above.

            Christopher no Newbie

            Hi,

            does anybody know if remoting mechnism is supported with home objects? Because I can?t get them work together! I get the error which is listed below. It says that method is not found. But if there isn?t ?extends EntityHome? the invoked method can be found somehow.
            I can?t understand that!
            I'm using jboss-seam-CVS.2007-09-07 and JBoss AS 4.2.
            Thanks in advance for any explanation.

            • 3. Re: Error while using remoting with Home objects?
              Christopher no Newbie

              Hi,

              actually the solution is easy (as the stack trace says) :). We have to override public void create() method from EntityHome class in our extended session bean class and then make it available in session bean business interface as @WebRemote.


              /*TestAction.java*/
              @Stateless
              @Name("testAction")
              public class TestAction extends EntityHome<Category> implements TestActionInterface{
              
               public String testName(String name){
               return "Hello, "+name;
               }
              
               
               public void create(){}
              
              
               @Remove
               public void destroy(){}
              
              
              }
              
              
              /*TestActionInterface.java*/
              
              @Local
              public interface TestActionInterface {
               @WebRemote
               public String testName(String name);
              
               
               @WebRemote
               public void create();
              
              
               @WebRemote
               @Remove
               public void destroy();
              }
