"jBPM 5 in JBoss 5/6 appserver - start and resume" To view the discussion, visit: http://community.jboss.org/message/583477#583477 -------------------------------------------------------------- I'm wondering what the best way to initialise/launch drools flow in an appserver would be. I need to be able to support persistent workflows with transactions so that if I kill the appserver I can restart back to where I was. Long term, cluster failover (which is a similar requirement) would also be required. I suspect that I should probably use some sort of ejb (stateless session bean or message driven bean) that initialises or resumes the process instances in the ejbCreate() method (since I believe using an ejb can help me support cluster failover as well). How do you resume a bunch of persisted workflows? They would all either be waiting on an event, the presence of a fact in their session or a return from a call out to a work item (either a domain specific node or a human task). When you restart, how do you recover the old session objects? Do you create and load a new KnowledgeBase? If the session is persisted I suppose there must be a hibernate query I can make to find all the existing instances. What do I do with them then? I'm actuallly struggling working out what the right question is :-) In short, I want to use jBPM in the JBoss appserver and have workflow instances reliably span restarts. thanks. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/583477#583477] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034]
