UserTransaction in non-EJB beans

[cjalmeida]

@SessionScoped
public class MyNonEJBBean {

    @PersistenceContext
    EntityManager em;

    @Resource
    UserTransaction utx;

    public doSomeWork() throws Exception {
             utx.begin();
             Order order = em.find(Order.class, "ID");
             order.setName("newname");
             em.persist(order);
             em.flush();
             utx.commit();
    }

The code above fails with a transaction not active exception on flush(). It seems that the injected EntityManager is not bound to the UserTransaction.

My bad. Had to call joinTransaction(). I was spoiled by Seam2 managed transactions. :)

While Seam3 Persistence is pending a release, I developed my own poor man @Transactional interceptor. Even though I still have to call joinTransaction(), a lot of boilerplate code is gone.
