Hi all, I am trying to get Drools working with OpenJPA. Currently I am stuck on the named query "ProcessInstancesWaitingForEvent". The term "in elements(..." seams to be Hibernate specific and can not be compiled by the OpenJPA JPQL compiler. Is there any workaround for this problem? thx Alexander -- View this message in context: http://drools.46999.n3.nabble.com/Drools-and-OpenJPA-tp3290343p3290343.html Sent from the Drools: User forum mailing list archive at Nabble.com.
