	private static JpaUtil instance;

	private EntityManagerFactory emf = Persistence.createEntityManagerFactory("default");

	private JpaUtil() {
	}

	public static JpaUtil getInstance() {
		if (instance == null) {
			instance = new JpaUtil();
		}
		return instance;
	}

	public EntityManager criarEntityManager() {

	}

	public void fecharEntityManager(EntityManager em) {
		if (em != null && !em.getTransaction().isActive()) {
