      • create a bean annotated with @Named
      • inject the statelss session bean into the @Named bean using @EJB
      • create a method in the @Named bean in which you access the injected stateless session bean
      • bind the created interceptor to that method using @Interceptors annotation

    Description

      I have a @Named bean in which I'd like to inject a component, using @Inject as well as a stateless session bean, using @EJB. The ejb is accessed using the no-interface view. Both references get injected properly in that case, but when I use an interceptor on one of the methods, only the references annotated with @Inject get injected, whereas those annotated with @EJB don't.

      The interceptor doesn't need to do anything special, this behaviour occurs even if only proceed() is invoked on the invocation context - the interceptor is always invoked correctly.

      The following snippet explains the issue:

      @Named
      public class MyController {

      @EJB
      private MyDao dao;

      @Interceptors(MyInterceptor.class)
      public void control()

      { dao.doDataAccessStuff(); /* NPE */ }

      }

      ---------------------------------------------------------------
      @Stateless
      public class MyDao {

      public void doDataAccessStuff()

      { ... }

      }
      ---------------------------------------------------------------
      public class MyInterceptor {

      @AroundInvoke
      public Object intercept(InvocationContext context) throws Exception

      { return context.proceed(); }

      }
