Bean managed Stateful Transactions

[Jarrod Felino]

Please look at the code below. Essientiallu I have 1 stateful bean with an extended context. I want the transaction to start on the start() method. Then I want
the transaction to be committed on the end() method. However when I execute the end() method I get a TransactionRequiredException. How come this is happening?
Shouldn't the transaction be carried over from the start() method? Or does this only work with CMP ?

@Stateful
@TransactionManagement(TransactionManagementType.BEAN )
public class WhaleBean implements WhaleInterface{
 
@Resource
SessionContext ctx;
@Resource
UserTransaction ut;

@PersistenceContext(unitName="titan", type=PersistenceContextType.EXTENDED)
EntityManager et;


@Override
public void start() throws NotSupportedException, SystemException, SecurityException, RuntimeException, Exception, Throwable, HeuristicRollbackException {
 
ut.begin();

Customer c = new Customer();
c.setAge(44);
c.setFirstName("Cam");
c.setSurname("Z");
et.persist(c);

}
 
@Override
@Remove
public void end() throws SecurityException, IllegalStateException, RollbackException, HeuristicMixedException, HeuristicRollbackException, SystemException {
Customer c = new Customer();
c.setAge(44);
c.setFirstName("R");
c.setSurname("VD");
et.persist(c);
et.flush();
ut.commit();
}
 
}

I am pretty sure now it is because I started up 2 different context from 2 different clients. As such the transaction was not preserved between the two different clients.
