[rules-users] Using the drools as the backend engine for a service

[Jai Vasanth]

I must have not been clear, yes I was planning on instantiating the rulebase
when the service starts and instantiating a new session for every request.



ONCE:

 RuleBase ruleBase = RuleBaseFactory.newRuleBase();
ruleBase.addPackage( pkg );

PER REQUEST:
Stateful session = ruleBase.newStatefulSession();  (Is this what you were
referring to as working memory ? )


I hope that looks ok.

Thanks

Jai
