The stateless session is just a convenience wrapper around the stateful session.

It avoids the need to call dispose()." -----Original Message----- From: [email protected] [mailto:rules-users- [email protected]] On Behalf Of Wolfgang Laun Sent: 20 October 2010 12:34 To: Rules Users List Subject: Re: [rules-users] Stateless K-Session but no Sequential Mode If I understand this correctly, there isn't much point in having a non-sequential-mode stateless session. If I want a one-shot execution, I can call inserts, fireAllRules and dispose() just as well in a stateful session. Possibly this is due to past development.

Fire all activations. 4. Done. None Sequential (Standard) mode: 1. Insert facts. 2. Create initial activations. 3. Pop and fire highest salience activation. 4. Update activations (if update, retract etc was performed). 5. If there are more activations goto 3. 6. Done. They key difference is that in the standard mode rule consequences can activate and deactivate activations as they update the working memory.

To turn it on, either call..." This tells me about a StatelessKnowledgeSession WITH sequential mode. So, what if I create a StatelessKnowledgeSession from a KnowledgeBase, but do not turn sequential mode on?

What the documentation does not tell me (or I haven't seen it) is the difference of a Stateless Knowledge Session with and without Sequential Mode.
