    EXTENDED @PersistenceContext @Produces

      Hi,


      I have a question how to make a extended PersistenceContext producer.I want to have an annotation @ExtUserDatabase. I tried like this:


      @Stateful
public class UserExtDatabaseProducer implements Serializable {
    @Produces @RequestScoped @ExtUserDatabase @PersistenceContext(unitName="userPU", type=PersistenceContextType.EXTENDED)
    public static EntityManager extendedItrackDatabase;
}



      I have also problems with implementing producer for non extended entitymanager (from here)


      class UserDatabaseProducer {
   @Produces @UserDatabase @PersistenceContext(unitName="userPU")
   static EntityManager userDatabase;
}



      I always getting an error:


      WELD-000044 Unable to obtain instance from org.jboss.weld.bean-...




      If I do it like so (without static), it works:


      public class UserDatabaseProducer implements Serializable {
    @Produces @UserDatabase @PersistenceContext(unitName="userPU")
    public EntityManager itrackDatabase;
}



      thanks.

              According to the JPA spec you can't do extended persistence contexts outside of a stateful session bean.
              Also according to the CDI spec the container is not required to support resources with scope other than @Dependent.


              These is a preliminary version of the seam managed persistence context in seam-persistence availible, but you have to build it yourself:


              https://anonsvn.jboss.org/repos/seam/modules/persistence/trunk/


              You use it as follows:


              @RequestScoped
@Produces
@PersistenceUnit
@ExtUserDatabase
public EntityManagerFactory emf;



              and then you can inject the seam managed PC :


              @Inject
@ExtUserDatabase
EntityManager entityManager;

                Also, according to the spec, a non-static field of a session beans cannot be annotated @Produces (hence resources cannot be defined that way).
