How do intercept specific interface in java?

Question

In MyInterceptor , which interface, Ifclocal or IfcRemote , invoked the method doStuff in MyEjb ? It's possible know through which "channel" your bean was called? I need know which dependency injection invoked the method.

@Local
public interface IfcLocal {
void doStuff(String s);
}

@Remote
public interface IfcRemote {
  void doStuff(String s);
}

@Stateless
@Interceptors({ MyInterceptor.class })
public class MyEjb implements IfcLocal, IfcRemote {
  @Override
  public void doStuff(String s) {
     System.out.println(s);
  }
}

public class MyManagedBean {
  @EJB private ifcLocal ifcLocal;
  @EJB private IfcRemote ifcRemote;

  public void go() {
    ifcLocal.doStuff("xxx");
    ifcRemote.doStuff("xxx");
  }
}

public class MyInterceptor {
  @AroundInvoke
  public Object intercept(InvocationContext inv) throws Exception {
    // ??? who invoked ???
    System.out.prinln(inv.getTarget().getClass()); // print MyEjb 
  }
}

Inject @Resource private SessionContext sessionContext; in MyInterceptor . After: Class<?> interfaceReference = sessionContext.getInvokedBusinessInterface() .
