JTA Application Managed EntityManager question

[Benoît de Chateauvieux]

Hi all,

I want to test the use of EntityManager.joinTransaction() in the case of BMT.

I wrote a simple method in my class annotated with @TransactionManagement(TransactionManagementType.BEAN):

MyEntity me;
EntityManagerFactory emf;
EntityManager em;
        
emf = Persistence.createEntityManagerFactory("JtaAppliManagedEM");
em = emf.createEntityManager();
me = new MyEntity();
me.setId(200);
try {
            UserTransaction ut = ctx.getUserTransaction();
            ut.begin();
            em.joinTransaction();
            em.persist(me);
            em.flush();
            ut.commit();
...

I have:

<persistence-unit name="JtaAppliManagedEM" transaction-type="JTA">

and I got the following error:

Caused by: javax.persistence.TransactionRequiredException: 
Exception Description: No transaction is currently active

Any idea?
Thanks a lot,

Beno�t

Move the emf.getEmtityManager after the ut.begin()

For the EJB, default transaction management type is CONTAINER and default transaction attribute for a business method is REQUIRED. So even though we did not specify transaction attributes in our bean class, defaults took over.

But for Bean manager Transaction as here.... Nothing is specified...???
Hence the Answer.

Then, what do you want to say other than what Shivreet Sekhon has already said ? What do you suggest ?
