Hi,
I'm completely stumped. I had a working configuration and I think the jbpm.cfg.xml file has been overwritten by someone. Now I can't get JBPM working again.
I'm using JBPM3.2.2 in JBOSS4.2.2. I had a Client which did a remote lookup of a SessionBean, this bean contained methods such as
deploy
createProcessInstance
storeInContextInstance
and so on.
Anyway to the problem;
I'm getting the following exception when I try to signal the process instance. The processDefinition I'm using runs fine "out of the container" which leads me to believe the issue is with the configuration of hibernate from JBPM.
It is only jbpm.cfg.xml which has changed, it is

I can see from the DB that the process definition is deployed fine.
I was sure that in my previous jbpm.cfg.xml file that I did not have the tx sevice defined! Is this possible?
Any help would be appreciated, I have been fighting with different issues in JBPM for a couple of weeks now and thought I had it cracked until this most recent issue.
Since it is running in the AS then I do not have a unit test that I can post. As I say this was working this morning!
Regards Alan
