BMT issue: EJBException Stateful instance org.jboss.as.ejb3.component.stateful.StatefulSessionComponentInstance is already associated with tx

[guinotphil]

Hello,

I’m currently having some issues with transaction management with BMT on JBoss AS 7.

This is in a Seam 2 application which is currently in production on JBoss AS 4. I’m not really sure about the origins of the problem, but I’ll try to give the maximum of details.

I’ve got an EJB with look something like that:

@Stateless(name="path/processManager")

@Name("path.processManager")

@AutoCreate

@TransactionManagement(TransactionManagementType.BEAN)

@JndiName("java:app/MyEjbProject/path/processManager")

public class ProcessManagerAction implements ProcessManager

{

    @Logger

    private Log log;

    @Resource

    private UserTransaction userTransaction;

    @PersistenceContext(unitName="entityManagerFactory")

    EntityManager em;

    public static ProcessManager instance() {

        return (ProcessManager) Component.getInstance(ProcessManagerAction.class);

    }

    static void beginTransaction(UserTransaction userTransaction, EntityManager em) {

        try {

            if (userTransaction.getStatus() == Status.STATUS_NO_TRANSACTION) {

                userTransaction.begin();

                em.joinTransaction();

            }

        } catch (Exception e) {

            log.error("Cannot begin transaction", e);

            throw new IllegalStateException("Cannot begin transaction", e);

        }

}

    static void commitTransaction (UserTransaction userTransaction, EntityManager em)

        try {

            if (userTransaction.getStatus() != javax.transaction.Status.STATUS_ACTIVE) {

                throw new IllegalStateException("No transaction active");

            }

            em.flush();

            userTransaction.commit();

       } catch (OptimisticLockException e) {

            throw e;

       } catch (EntityNotFoundException e) {

            throw e;

       } catch (Exception e) {

            log.error("Cannot commit transaction", e);

            throw new IllegalStateException("Cannot commit transaction", e);

       }

}

    public Object process(Object param) {

        beginTransaction(userTransaction, em);

        << some business code>>

        commitTransaction(userTransaction, em);

        return result;

    }

}

When I enter into the process method, the userTransaction is an instance of com.arjuna.ats.internal.jta.transaction.arjunacore.UserTransactionImple

(The trace-logged EJBException is then thrown)

As you can see, since I started running the process method, the only transaction logged is the current one : 0:ffffc0a80a80:354a2ce5:4e6f491c:175

The other transaction, 0:ffffc0a80a80:354a2ce5:4e6f491c:16f, is however still associated with the StatefulSessionComponentInstance but has been suspended as logged before.

Any idea on this? It is possible that it comes from a misconfiguration, the set up is very big (can’t attach the whole application sorry) as it use Seam 2, Hibernate 3 and also jBPM 3 (which I managed to patch to obtain the Hibernate SessionFactory from the EntityManagerFactory in JNDI), etc, etc.,

In a similar way, if I use Seam 2 to get the transaction instead of the injection:

    public Object process(Object param) {

        UserTransaction userTransaction = org.jboss.seam.transaction.Transaction.instance();

beginTransaction(userTransaction, em);

        << some business code>>

        commitTransaction(userTransaction, em);

        return result;

    }

The UserTransaction is time is an instance of org.jboss.seam.transaction.UTTransaction

Then, I the same EJBException is thrown during the beginTransaction while I had the exception only during business code when I was using the injected UserTransaction instance.

Thank you very much for any help !

[jaikiran]

Can you post that entire exception stacktrace? That will help us understand the flow a bit more better. Also which exact version of JBoss AS7?

[guinotphil]

Sorry, JBoss AS 7 is a nightly build downloaded on September 9th.

Here is the stack trace of course:
