hi all,
when running jbpm3.2.6 on jboss portal 2.7.2 the following error occurs in the start up of the JobExecutorThread.
| 22:25:37,101 ERROR [JobExecutorThread] exception in job executor thread. waiting

|
the problem is with jbpmContext.getJobSession(), as it can't get a user transaction.
| protected Collection<Job> acquireJobs() {
| Collection<Job> acquiredJobs = Collections.emptyList();
| synchronized (jobExecutor) {
| JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
| try {
| log.debug("querying for acquirable job...");
| String lockOwner = getName();
| JobSession jobSession = jbpmContext.getJobSession();
|
|
i am using the JtaDbPersistenceServiceFactory which has the isTransactionEnabled =false;
| <jbpm-context>
| <service name="persistence" factory="org.jbpm.persistence.jta.JtaDbPersistenceServiceFactory" />
|
|
WHat is going on here?
Why cant the java:comp/UserTransaction be found?
-lp
