I'm running into the same problem using jbpm-3.1.1, hibernate-3.2.4.SP1 and
JBoss 4.0.5.GA.
But I'm using this testcode (with a minimum-workflow consisting of a start and
an end node) as CMT bean:
public void showError() {
|
| log.info("Request received");
| JbpmContext wfContext = wfConfiguration.createJbpmContext();
| ProcessInstance process =
wfContext.newProcessInstance("HelloWorld");
| process.signal();
|
| // Session hibernateSession = wfContext.getSession();
| wfContext.close();
| }
|
As single session bean method called by a servlet.
JBoss closes the JDBC connection

Does anybody know why JBoss is closing the connection just a few milliseconds
before JBPM tries it itself?
I'm using a clean JBoss 4.0.5.GA with hibernate tree cache as MXBean and JBPM
and Hibernate as POJO inside the EAR file (consisting of the small session bean
above and the servlet calling that session bean).
