Users may also use the EntityManager API outside the container. You may use the org.eclipse.persistence.jpa.JpaHelper class to obtain an EntityManager.
Using a server session
EntityManagerFactory emf = org.eclipse.persistence.jpa.JpaHelper.createEntityManagerFactory(serverSession);
EntityManager em = emf.createEntityManager();
Using a sessions.xml file
EntityManagerFactory emf = org.eclipse.persistence.jpa.JpaHelper.createEntityManagerFactory(sessionName);
EntityManager em = emf.createEntityManager();
Or you may use an EntityManager from a persistence.xml file.
Using a persistence unit name
EntityManagerFactory emf = Persistence.createEntityManagerFactory(persistenceUnitName, propertiesMap);
EntityManager em = emf.createEntityManager();
