[jboss-user] [EJB/JBoss] - how to turn on ejb transaction demarcation?
hello!
i have jboss-4.2.3GA and example from jboss-seam-2.1.1.GA sources (seam-booking)
i want to save user in a transaction and then change his name in another transaction, so
some changes were made in RegisterAction.java:
public void register()
| {
| if ( user.getPassword().equals(verify) )
| {
| List existing = em.createQuery("select u.username from User u where
u.username=#{user.username}")
| .getResultList();
| if (existing.size()==0)
| {
| persistUser();
|
| user.setName(user.getName() + "1");
| persistUserWithException();
|
| facesMessages.add("Successfully registered as
#{user.username}");
| registered = true;
| }
| else
| {
| facesMessages.addToControl("username", "Username
#{user.username} already exists");
| }
| }
| else
| {
| facesMessages.addToControl("verify", "Re-enter your
password");
| verify=null;
| }
| }
|
| @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
| private void persistUser() {
| em.persist(user);
| }
|
| @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
| private void persistUserWithException() {
| em.persist(user);
| throw new RuntimeException();
| }
this expects that user with original name will be persisted, but change of his name
won't apply.
but this doesn't work. both operations will be rollbacked because they are in the same
transaction.
what's wrong? please help me!
