The key point is the jbpm4 using org.hibernate.Session to access Database,  So I am afraid at this moment, we couldn't use JPA directly.  Maybe someone could provide a JPA DbSession implementation to achieve this feature. For the TransactionManager issue, I think we could use the PlatformTransactionManager which was provided by spring,  You could refer Developer Guide to get more information about how to integrate spring and jbpm-4.x http://docs.jboss.com/jbpm/v4/devguide/html_single/#springIntegration http://docs.jboss.com/jbpm/v4/devguide/html_single/#springIntegration -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/555332#555332] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
