Re: [rules-users] IllegalStateException:

Raj, I'd like to see how you used to create the KieSessions before. If you just did: KieContainer.newKieSession() that might not work You should instead be able to do: KieBase.newKieSession(), but create the KieBase only once, not every time you need a KieSession (assuming that all sessions will essentially use the same rules) The way you do it now works, but has a heavy impact on performance, since you recreate the KieBase every time.

Kiebase is thread safe.
