[jboss-user] [JBoss Seam] - Re: Trouble W/ NullPointerException

[damianharvey]

Well not knowing your components.xml, I'd hazard a guess that maybe you should check that your entityManager is null? Put in a log line checking something like 'em==null' (or run it through a debugger).

And why not use @In
  | EntityManager entityManager;rather than PersistenceContext? You define your entityManager in your <persistence:managed-persistence-context> in your components.xml. 

Cheers,

Damian.
