Hi Alan, for using Dependeny injection in your Unit Tests (which are actually application clients), you have to do some very special tasks to start it. Here is a doc which describes the required steps for a standalone application client: http://www.jboss.org/community/wiki/HowtouseanapplicationclientinJBoss-5 But I fear this cannot be applied to JUnit, as you cannot use "org.jboss.client.AppClientMain" to run a test. So I think you have to perform a JNDI lookup in the JUnit tests. Best regards Wolfgang View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4248389#...
