Hi nizzy, I am not sure what exactly you are tryign to do int eh client, but as per your last stacktrace i think you are using your own hibernate session to update the database or closing the jbpmcontext between your methods anonymous wrote : deploy | createProcessInstance | storeInContextInstance Eitehr you need to start a seperate transaction and mange the operations with in that new transaction or do all the operations in one single method/call. hope this may help you.
