Hi, If you're talking about the RequestDispatcher#forward method, the Servlet Spec guarantees that it will execute on the same thread as the original request (Servlet Spec v2.4, section SRV.8.2, it's unambiguous), so that's what you're missing there. For EJB calls, I don't know, you might be right. I don't work with them as much nowadays, so I don't remember the spec as well.
