This session was previously disposed." To view the discussion, visit: https://community.jboss.org/message/798781#798781 -------------------------------------------------------------- problem is that you try to use (probably by mistake) a disposed session:                    // Let's reload the session                   StatefulKnowledgeSession loadedKsession = JPAKnowledgeService.loadStatefulKnowledgeSession(sessionId, kbase, null, env);                   // All the listeners and WorkItemHandlers are volatile, so we need to register them each time that we reload the session                   //  from the DB.                   LocalHTWorkItemHandler localHTWorkItemHandler2 = new LocalHTWorkItemHandler(client, *ksession*); ksession (marked in bold) is disposed session and thus should not be used any more. Use instead session that you just loaded (loadedKsession) and the program will work just fine.
