Kris, As far as I can see, JPAWorkItemManager isn't used. When loadStatefulKnowledgeSession is called in class JPAKnowledgeServiceProviderImpl, a new instance of CommandBasedStatefulKnowledgeSession is returned. If you look at the getWorkItemManager method of this class, it returns an instance of an anonymous local class - it doesn't appear to be reading the property to determine which work item manager factory to use.
Thanks for looking at this, Alan Kris Verlaenen <kris.verlae...@cs.kuleuven.be> 26/08/2009 10:40 To Rules Users List <rules-users@lists.jboss.org>, alan.gai...@tessella.com cc Subject Re: [rules-users] When is JPAWorkItemManager used in Drools Flow? Alan, The JPAWorkItemManager should be used instead (automatically) as it is defined in the session configuration properties (earlier in the same method): props.setProperty( "drools.workItemManagerFactory", "org.drools.persistence.processinstance.JPAWorkItemManagerFactory" ); Are you encountering problems where the JPAWorkItemManager is not being used?
