java.lang.IllegalStateException: EntityManagerFactory is closed(Glassfish)
I am getting this exception when i try to execute a jpql query. My EJB interface and DAO which implements it are:
@Local public interface DeckInter
@Stateless public class DeckDAO implements DeckInter < @PersistenceContext(unitName = "NewPersistenceUnit") private EntityManager em; private ListdeckList; public String findDeck(String name) < try < Query query = em.createQuery("select d from Deck d"); deckList = query.getResultList(); return deckList.get(0).getDname(); >catch (Exception e) < e.printStackTrace(); >return "test"; > i am getting the «test» return , because the first one throws the exception. The persistence.xml is :

I’m developing a small stock control application using Java-SE8, JPA and Hibernate and this is my first contact with ORMs and the Persistence API. All was fine, but my tests failed when I created a method to retrieve things on the database(MySQL) and I get an:
I really don’t know what is happening and spent almost two days trying to fix this. Can anyone help me, please? Here are the pieces of code that trigger the error.
