[jboss-user] [JBoss Seam] - Re: ResourceBundle in Database

[Zerg-Spirit]

Thanks, it helped me a lot!
Now, I kinda understood how it's working, but my very last problem is pretty tough: I can't retrieve the EntityManager in my Session Bean extending ResourceBundle.

@Stateless
  | @Scope(SESSION)
  | @Name("dbResourceBundle")
  | public class DBResourceBundle extends ResourceBundle implements iDBResourceBundle{
  | 
  | 	@PersistenceContext
  | 	private EntityManager em;
  | 
  | 	private List<CustomResourceBundle> availableResourceBundles;
  | 	
  | 	public DBResourceBundle(){
  | 		System.out.println("EntityManager: "+em); //em is null :/
  | 		try{
  | 			availableResourceBundles = em.createQuery("select rb from CustomResourceBundle rb").getResultList();
  | 		}
  | 		catch(Exception e){
  | 			//null pointer exception cause em is null.
  | 			e.printStackTrace();
  | 			
  | 		}
  | 	}
  | ...
  | 

CustomResourceBundle being an entity bean representing a 'bundle' for the given language.
How to retrieve a workable EntityManager?
My guess is that when this Session Bean is instanciated, the PersistenceContext isn't created yet.
