Re: [rules-users] Can Drools Flow Persistence Work without JTA

as it turned out if one uses EntityManager configuration as I described in my previous post and at the same time runs actions async by spawning new threads then marking workItems as being completed can be a little tricky as it's very easy to see "EntityManager has been closed" exception. The solution to this problem is to use knowledgeSession that has been created when the task was being created. i.e. MyWorkItemHandler implements WorkItemHandler { //pass this session as a part of registering workitemhandler private StatefullKnowledgeSession knowledgeSession; public void executeWorkItem(final WorkItem workItem, final WorkItemManager workItemManager){ Thread t = new Thread(){ @Override public void run() { action.execute(processContext, domainInstance); //don't use passes workItemManager as its entityManager has been already closed (we're running tasks async) knowledgeSession.getWorkItemManager().completeWorkItem(workItem.getId(), action.getResults()); } }; //start action async t.start(); } } -- View this message in context: http://drools.46999.n3.nabble.com/Can-Drools-Flow-Persistence-Work-withou...
