Injecting EntityManager in a servlet

As the Sun's JEE tutorial, you can inject EntityManager/EntityManagerFactory in servlet or a class implementing ServletContextListener. I have a sample application that injects EntityManagerFactory in a class implementing ServletContextListener. It is working fine with the application server GlassFish. I tried to the same thing with JBoss. The EntityManager was never injected. It was always null. Can someone help me out.
It is sorta covered in the JavaRanch Style Guide.
