Ibernazione.cfg.xml:

Ibernazione.cfg.xml e persistenza.xml sono memorizzati nella cartella project / META-INF e ricevo un errore su

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

Traccia dello stack:

javax.persistence.PersistenceException: No Persistence provider for EntityManager named firstOne
