Unable to locate current JTA transaction

[crussell42]

When I deploy the jbpm-enterprise.ear to jboss 4.0.5ga and try to log into the
jbpm-console web app I am getting the following error.
Unable to locate current JTA transaction

Here is the pertinent hibernate.cfg.xml part

 <!-- JBoss transaction manager lookup (begin) -->

 <!-- JBoss transaction manager lookup (end) -->

http://www.jboss.com/index.html?module=bb&op=viewtopic&t=99366&postdays=0&postorder=asc&start=0
Found the solution in this posting.
Had to change config option in jbpm.cfg.cml to false.
Not sure why this is but it seems to fix things

 <field name="isCurrentSessionEnabled"><false /></field>

[crussell42]

ALthough the jbpm-console seems to work like this, lots of exceptions are spewed mostly

org.hibernate.TransactionException: Could not register synchronization for container transaction Could not register synchronization for container transaction.

So is there a nice easy way to turn on JTA or CMT ?
See the post mentioned above as it philosiphises but never determines
how to make 3.2.beta1 use either CMT or JTA it only describes how
to disable isCurrentSessionEnabled.

In poking around and finally getting into building jbpm-enterprise.ear from the
cvs head, I got a little further in my testing. Because I cant figure out how to configure transactions properly, I just tried to turn them off by editing the
jbpm.cfg.xml and setting

<field name="isCurrentSessionEnabled"><false /></field>
<field name="isTransactionEnabled"><false /></field>

Then I started getting some exceptions withing the JbpmPhaseListener and started lookuing at DbPersistenceService and found this bug.
http://jira.jboss.com/jira/browse/JBPM-833
I fixed my source version and this gets me to the next set of exceptions.
These seem to have to do with jini naming of the
TimerServiceBean. For some reason when I deploy the ear, jboss is picking up and configuring the CommandServiceBean properly to "ejb/CommandServiceBean" but
the TimerServiceBean is not being registered as expected

14:55:45,045 INFO [EARDeployer] Init J2EE application: file:/usr/local/jboss-4.0.5.GA/server/messaging/deploy/jbpm-enterprise.ear

14:55:47,736 INFO [BaseLocalProxyFactory] Bound EJB LocalHome 'TimerServiceBean' to jndi 'local/TimerServiceBean@743673026'

And so we get the exception and message "ejb local timer lookup problem".
Could use help here if anyone has an idea???

[crussell42]

Also needed to apply this fix for compiling the cvs head.
http://jira.jboss.com/jira/browse/JBPM-834

All I wanted was a Pepsi !!!

No really, I'm just trying not to lose any information on how to get the beast to run with Jboss 4.0.5GA, ejb3, jms messaging, and annotated class persistence in a ContextInstance. This forum will help me do that and maybe help others.

Ok, doing pretty well now but when I try to signal a transition to an end state I get the following:
See JIRA ISSUE http://jira.jboss.com/jira/browse/JBPM-836

Ok, at this point things are running pretty well.
I have deployed the cvs trunk build jbpm.3 (3.2.beta2)'s jbpm-enterprise.ear to
jboss4.0.5ga with ejb3 and messaging.
I am able to create start and transition through process;s.
Keep in mind the reason for this posting.
We have isTransactionEnabled set to false and isCurrentSessionEnabled set to false.
So here I almost have it working with Transactions turned OFF.
When a process transitions to an end state however and the clean up of the process instance begins, I get the following exception:

16:26:00,719 ERROR [STDERR] org.hibernate.TransactionException: Could not register synchronization
 at org.hibernate.transaction.CMTTransaction.registerSynchronization(CMTTransaction.java:159)
 at org.jbpm.db.JobSession.deleteJobsForProcessInstance(JobSession.java:214)
 at org.jbpm.scheduler.ejbtimer.EjbSchedulerService.deleteTimersByProcessInstance(EjbSchedulerService.java:165)
 at org.jbpm.graph.exe.ProcessInstance.end(ProcessInstance.java:276)

So back to the original question, HOW DO I PROPERLY CONFIGURE USE OF EITHER JTA OR CMT TRANSACTIONS?????????
I've managed to make it hobble along with the transactions turned off (I think) but what I really want is to properly configure transactions....
PLEASE HELP!

I am also getting the same error. I am working on jbpm3.2.2\jbpm-jpdl-3.2.2 & websphere 6. I am able to connect and give token.signal but at state-end i am getting this error.

I ran into http://jira.jboss.com/jira/browse/JBPM-836 some time ago on 3.2.1 and applied the fix to jbpm-enterprise.ear. Quite surprised to run into it again after my upgrade to 3.2.2.

Could this be permanently fixed in the next release ?

[kukeltje]

The issue was never formally fixed (it is still open). So no real surprise that it is still an issue in 3.2.2. I've set the fix version to 3.3 so it does not slip of the radar

[kukeltje]

3.2.3 that should say.

org.jbpm.db.JobSession deleteJobsForProcessInstance org.hibernate.TransactionException: Could not register synchronization

Can you please help me. I already running behind time. and saw all sites from almost 2 weeks. but still not getting any solution.....

I don't have a solution, but I'm experiencing the same problem, I think. In my case, I'm manually clicking "End" while viewing a process instance in the jbpm-console web app.

I've followed the stack traces and found that the reason that the synchronization couldn't be registered is because of a NullPointerException that occurs inside CMTTransaction on line 156:

154: public void registerSynchronization(Synchronization sync) throws HibernateException {
155: try {
156: getTransaction().registerSynchronization(sync);
157: }
158: catch (Exception e) {
159: throw new TransactionException("Could not register synchronization", e);
160: }
161: }

So for some reason, getTransaction() is returning null...
