nothing persisting?

[ibivibiv]

I've used JBPM back in version 2 and I have set up the 3.2.2 version recently. I've noticed quite a few changes in the use of the context and the lack of use of the JBPMSession. I can start and move processes along all day and all night, but there is nothing in my JBPM_XXXInstance tables. No processes, tasks, etc. Did something change or am I still suppose to use the JBPMSession to allow for persisting?

The JTADBPersistenceServiceFactory seems to be my culprit. Switching to the DBPersistenceServiceFactory solved the issue for me.

So, now that I know that the JTA persistance is not committing, can anyone give me a hint as to the why? I'll paste my config and a quick example of a MDB that starts a process that never commits to the database.

<jbpm-configuration>

 <jbpm-context>
 <service name="persistence" factory="org.jbpm.persistence.jta.JtaDbPersistenceServiceFactory" />
 <!--<service name="persistence" factory="org.jbpm.persistence.db.DbPersistenceServiceFactory" />-->

 </jbpm-context>

 <!-- use the context class loader -->
 <string name="jbpm.classLoader" value="context" />

 <!--
 Note, that the default job executor needs to be overwritten with a null value.
 In the enterprise configuration there should be no job executor.
