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???

|

|
my workflowInterceptor is:
| package com.santex.darwin.service.interceptor;
|
| import javax.interceptor.AroundInvoke;
| import javax.interceptor.InvocationContext;
|
| import org.jboss.seam.contexts.Contexts;
|
| /**

| 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.Retention;
