EntityManagerFactory emf = Persistence.createEntityManagerFactory("test");

EntityManager em = emf.createEntityManager();

and I'm getting the following error:

javax.persistence.PersistenceException: No Persistence provider for EntityManager

but it is a call in a class out of the SessionBean Class.

in the sessionBean class I'm using (see below) in order to get the entityManager

however I also need to acess the database out of the sessionbean class. For that, I have tried the EntityManagerFactory without success.

I'm new on it, and I don't have any idea to solve it.

Could you please help me in how I can overcome such problem?

Kind Regards
