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?
