I have JBoss 4.0.3SPI with an EJB RC5 patch. I am able to deploy a Hibernate Entity Manager using persistence.xml, and even place it in JNDI. I can access the entity manager via JNDI, but cannot access using direct injection. My injection code is:

@PersistenceContext(unitName="vramPu") // I've tried with/without name
EntityManager em

...

// Access em
em.<someMethod>

Each time I get an NPE.

Now, if I access via JNDI, it appears that I am now in BMP, since I need to add transactional behavior to the code. *Then*, there seems to be an issue with how this is done. Do I use UserTransaction, which requires javax.ejb.Resource which doesn't appear to be part of the RC5 specification???

I could really use some advice from anyone who has successfully used the hibernate entity manager with JBoss 4.0.3SP1. Thank you.
