I am trying for hours already to get this tutorial to work in JBoss 4.2.0:
http://www.eclipse.org/webtools/jst/components/j2ee/scenarios/jee5_application_creation_tutorial.html

I always get a NPE with that:
@PersistenceUnit(name="EJBProject1") EntityManagerFactory emf;

...
...
(inside a method)
EntityManager em1 = emf.createEntityManager(); // <== This causes a 
NullPointerException

Maybe its related to this: 
http://www.jboss.com/index.html?module=bb&op=viewforum&f=221
but I can't figure out how to fix it. Any help is appreciated. 
The eclipse project files can be downloaded here:
