[jboss-user] [JBoss Seam] - interceptor in ejb-jar.xml doesn't works

[juangiovanolli]

Hi:
     i created a new interceptor and i add it in ejb-jar.xml. this interceptor is a global interceptor, as you can see in my ejb-jar.xml shown below.
The problem is that the interceptor is never reached, That is, the workflowinterceptor is never loaded.
Any ideas???

  | 			</interceptor-class>
  | 		</interceptor-binding>
  | 	</assembly-descriptor>
  | 
  | 
  | </ejb-jar>
  | 

my workflowInterceptor is:


  | package com.santex.darwin.service.interceptor;
  | 
  | import javax.interceptor.AroundInvoke;
  | import javax.interceptor.InvocationContext;
  | 
  | import org.jboss.seam.contexts.Contexts;
  | 
  | /**
  |  * 
  |  * @author Juan Giovanolli
  |  * 29/12/2006
  |  */
  | public class WorkflowInterceptor
  | {
  |     @AroundInvoke
  |     public Object manageWorkflowRuntime(final InvocationContext invocation) throws Exception {
  |         
  |         if (invocation.getMethod().isAnnotationPresent(StartActivity.class)) {
  |             System.out.println("tiene el start");
  |         }
  |         if (invocation.getMethod().isAnnotationPresent(EndActivity.class)) {
  |             System.out.println("tiene el end");
  |         }
  |    
  |         return invocation.proceed();
  |     }
  | }
  | 
  | 

and my startActivity and endactivity annotations are 


  | /**
  |  * 
  |  */
  | package com.santex.darwin.service.interceptor;
  | 
  | import java.lang.annotation.ElementType;
  | import java.lang.annotation.Retention;
  | import java.lang.annotation.RetentionPolicy;
  | import java.lang.annotation.Target;
  | 
  | import javax.interceptor.Interceptors;
  | 
  | /**

  | @Target(ElementType.METHOD)
  | @Retention(RetentionPolicy.RUNTIME)
  | 
  | //@Interceptors(WorkflowInterceptor.class)
  | public @interface StartActivity
  | {
  | 
  | }
  | 
  | 


  | /**

  | package com.santex.darwin.service.interceptor;
  | 
  | import java.lang.annotation.ElementType;

  |

  | @Target(ElementType.METHOD)
  | @Retention(RetentionPolicy.RUNTIME)
  | 
  | //@Interceptors(WorkflowInterceptor.class)
  | public @interface EndActivity
  | {
  | 
  | }
  | 
  | 

the class where i testing this is this:
