Taking your advise, i store the session id and the work item id and can complete a process instance which has only one Huam Task. When my process has one more and the process instance reached the second Huam Task node, i can get an exception:
2011-04-18 10:59:17,773 ERROR [org.drools.persistence.SingleSessionCommandService] - Could not commit session
