Hello, I have just started looking at drools 4 to upgrade from drools 3. While reading the documentation, was wondering whether it is necessary to call session.dispose() after session.fireAllRules() for the StatefulSession. If I don't call session.dispose(), does that mean that the session will still be garbage collected? Also, Reading the documentation, I was not exactly clear for the difference between Stateful and Stateless sessions. Can you explain when StatefulSession and when StatelessSession can be used? Thanks. -- View this message in context: http://www.nabble.com/Drools-4-Stateful-Session-dispose-tf4437732.html#a1... Sent from the drools - user mailing list archive at Nabble.com.
