EntityManager lookUp in generics POJO

[sventevith]

Is any possibility to retrieve Entity Manager in generics POJO ?

I know that dependency injection annotations only works in EJB objects - not generic POJOs. Is possibility to get EntityManager via JNDI ??

Entity Manager JNDI name is not accessible in Global JNDI Namespace.

Please help.

no.
But what's wrong with having an EJB3 doing the DAO layer?

hey, I have the similar question, how to get the another session bean by the session bean already got the client, which is a generic POJO ?

As §5.3.2 of the EJB 3.0 PFD

In any SE environment you can do :

EntityManagerFactory emf =
javax.persistence.Persistence.createEntityManagerFactory("YourFactory");
EntityManager em = emf.createEntityManager();

Did you already tried that ?
As a POJO unmanaged is a SE, as long as the persistence.xml is configured it should work ...

Anyway, I do not see also what's wrong with EJB3 the DAO ;-)

I have a similar problem because I need an EntityManager in a custom hibernate validator class. It sure would be nice if I could just dependency inject it, but for now I'll just look it up in JNDI (the old fashioned way).
