Hi!

I'm trying to inject a EJB within my RESTful Service (RESTEasy) via Annotations.

public class MyServelet implements MyServeletInterface {

...

@EJB

MyBean mybean;

...

}

Unfortunately there is no compilation or AS error, the variable "mybean" is just null and I get a NullPointerException when I try to use it.

What I'm doing wrong?

Here are some side-informations about my architecture:

JBoss 4.2.2.GA
Java version: 1.5.0_17
local MDB-Project
remote EJB-Project
WAR Project with the RESTful Service which uses the remote EJB and sends messages to the local MDB-Project

Thanks in advance!

br Dominik

p.s: everything is working fine when I use normal context lookup.
