[rules-users] Persisted stateful sessions and knowledge base changes (revisited)

I have an Drools 5.5. application that persists a stateful session to a database. While it was running, I made some changes to my rules (via Guvnor). When I restarted my application it was no longer able to reload the persisted session: *Caused by: java.lang.RuntimeException: Unable to load session snapshot at org.drools.persistence.session.JPASessionMarshallingHelper.loadSnapshot(JPASessionMarshallingHelper.java:96)* FYI, I do not use a KnowledgeAgent because I have a lot of events coming in and I only want to load the knowledgebase changes when my application starts up. About two years ago, a discussion occurred on this topic (https://community.jboss.org/message/628586#628586). Unfortunately, I haven't seen much since but I am hoping that someone has concurred this problem (elegantly or otherwise). Is there a common way to solve this problem? Given a persisted session what are the steps needed to migrate it to the new ruleset? Thanks for any insight. -J -- View this message in context: http://drools.46999.n3.nabble.com/Persisted-stateful-sessions-and-knowled...
