[rules-users] Persistence and mina human task handling

Hello, I tried to setup a sample standalone "hello" application that attempts to run a process involving human tasks. Main components were: - mina task server (as documentation hinted, based on a sample), - standalone "hello sort of" application running a ruleflow with some workitems including a human task too, - eclipse human task view. I setup the persistence - following the documentation, asked for a jta datasource and used bitronix transaction manager. The application: - begins a new user transaction - creates a new process instance in a stateful session - calls fireallrules - waits on the console with System.in.read() (this was already a workaround to avoid completing the user transaction before the human task is handled in the HT view, this otherwise caused a nullpointer assigment at line 83 in JPAWorkItemManager which tried to refer to variable "em" which when set returned null for the following assignment if usertransaction were committed: EntityManager em = (EntityManager) this.workingMemory.getEnvironment().get( EnvironmentName.ENTITY_MANAGER );) ... following the above the message reaches the human task server, and then the task appears in the human task view - so far so good. Then when the task is started and completed in the view, the "GetCompletedTaskResponseHandler.execute()" begins handling the completed message. Unfortunately this call fails with : " no transaction started on this thread" I have then checked the threads in the debug view and looked like the message response is actually running in the "NioProcessor" thread. At this point I got stuck. If there is some guideance on how to correctly setup transaction management and Mina task client/human task work item handler it would be very much appreciated. thank you.
