Inject PersistenceContext with CDI

Question

Currently, I\'m using PersistenceContext to inject an EntityManager. The EM is injected perfectly.

@Stateless
public StatelessSessionBean implements Stateles         


        

Answer 1

@PersistenceContext is an EJB injection point, while @Inject is a CDI one

Actually, no. @PersistenceContext annotation can be used in CDI and is not connected with EJB. You can do something like this:

@Named
public class EntityDAO {
    @PersistenceContext
    private EntityManager manager;

    ...

}

EJB uses @EJB annotation to inject other EJB, but it can inject any CDI bean or persistence context with same annotations.
