CDI - using interceptor class from library

Question

Can we use annotation-based interceptor in ejb-jar from a different ejb-jar? I tried it with the @Logged example, but stucked with it. Can somebody help me out?

In core.jar:

@Inherited
@InterceptorBinding
@Retention(RUNTIME)
@Target({METHOD, TYPE})
public @interface Logged {}

and

@Logged
@Interceptor
public class LoggedInterceptor implements Serializable {

    private static final long serialVersionUID = 1L;

    public LoggedInterceptor() {
    }

    @AroundInvoke
    public Object logMethodEntry(InvocationContext invocationContext)
            throws Exception {
        System.out.println("Entering method: "
            + invocationContext.getMethod().getName() + " in class "
            + invocationContext.getMethod().getDeclaringClass().getName());

        return invocationContext.proceed();
    }
}

The question is: how to use this interceptor from another ejb-jar (inside an Enterprise Application)? For example: logging business method calls, where methods can be found in different modules:

module1.jar:

public class ModuleClass{
    @Logged public void doSomething(){...}
}

I've tried to put <interceptor><class..... to beans.xml too, but its not working for me.

Thanks for any advice!

That should definitely work, even though I recall that I fiddled quite a bit on JBoss 6.

You will have to activate the interceptor in the beans.xml of the JAR where it's defined, and I think there was an issue with EAR deployments, but that's quite a while ago and I don't have access to the source code any more.

Should that not work - play with the activation in the beans.xml in both JARs. Try to query the BeanManager if the interceptor is registered.
