Seam UserTransaction in wildfly 8.2.0

[pramanish]

Previously I was using seam 2.1 and JPA 1 along with JBOSS 5. In this configuration I was accessing user transaction using below code:

UserTransaction userTx = Transaction.instance();
  if (userTx != null) {
  boolean previousTransaction = Transaction.instance().isActive();
  if (!previousTransaction) {
  Transaction.instance().begin();
  }

  userTx.setTransactionTimeout(10 * 60);
  entityManager().joinTransaction();
  entityManager().persist(pur);
  entityManager().flush();
  userTx.commit();

  if (previousTransaction) {
  userTx.begin();
  }
  }
  }

After that I have migrated to seam 2.3 and jpa 2 along with wildfly 8.2.0. I can not access the user transaction with above code so can anyone please guide me on how to access the user transaction in wildfly 8.2.0.?

What I am primarily looking for is the way to immediately perist my changes when I do flush using entitymanagaer and it should not wait for method to exit.

Please guide me on this.

Hi Frank,

I have tried your code and I am getting following exception while getting the user transaction using the JNDI.

"java.lang.ClassCastException: org.jboss.tm.usertx.client.ServerVMClientUserTransaction cannot be cast to org.jboss.seam.transaction.UserTransaction"

Can you guide me further on this?

UserTransaction is of type javax.transaction.UserTransaction.
