"Re: JBPM5 running processess/tasks behaviour when App Server shutdown/restart" To view the discussion, visit: http://community.jboss.org/message/609010#609010 -------------------------------------------------------------- Hi Brkhard, Thanks for your response. I'm not using jbpm console ,I've integrated jbpm with my application and from there I start processes/task. Yes I was talking about long running task meaning process/task which is started but not finished and if we restart server then will it pick trigger again with same old session in sessioninfo table with that id=1 ? Mostly it works but sometime it doesn't complete the tasks after server restart may be because of old session is not used which had triggered those process/tasks. So new session gets created and that works fine to start new process/task. I'm using Oracle DB and on server(Tomcat) restart I test if JBPM sequence and tables is available then don't create new otherwise create new sequence/tables. Basically I need help related to session handling, I've notice some weird exception.Sometime after server restart I see "*java.lang.NullPointerException*" because ksession is null and hence while calling below line in CommandDelegate, application throw this exception. ksession.startProcess(processId, parameters).getId(); While server start,app looks for sessioninfo table for default id "1" otherwise commanddelgate class creates new session but sometime I see below exception(error laoding session snapshot) and it never create or use old session to trigger old or new process/tasks. Loading process AutoCyclicalRiskAssesment.bpmn Loading session data ... Error loading session data: java.lang.reflect.InvocationTargetException Error loading session data: java.lang.RuntimeException: Unable to load session snapshot 12:35:26,907 ERROR [CommandDelegate] java.lang.IllegalStateException: java.lang.reflect.InvocationTar getException So any help to handle session properly would be greatly appreciated .I need to know how to properly handle while server runs or if any server restart/shutdown/maintenance.
