Based on a short conversation on the drools-user list:

Is there any documentation on how to configure JBPM 5 with container managed persistence using EJB3. It works using bean managed persistence. But would make life much easier if I did not have to manage the tx myself.

...

Thanks for the reply. I use JBPM for some business transaction flow orchestration. I run the JBPM layer over a stateless session bean layer to manage business logic underpinned by jpa for persistence. My stateless session beans are all container managed beans so having JPBM use bean managed persistence is a bit messy in my architecture.
