[rules-users] Problem in Concurrent execution of Rules

Hi All, I am using JBOSS Drools 5.0. The problem which I am currently facing is concurrent execution of Rules. I am using RuleBase to get Session object i.e. RuleBase ruleBase = RuleBaseFactory.newRuleBase(); StatelessSession session = ruleBase.newStatelessSession(); Session.execute(ArrayList of Facts); In the application I am creating separate RuleBase and session object for each request of process. Now the Problem is as follows :- There are currently two users logged in the System. Suppose User 1 clicks a button to process 100 members of Data using Rules and User 2 clicks same button to process same 100 members of Data, When request of User 1 comes to Rule Engine, it starts processing its data but as User 2 comes to Rule Engine, The engine stops processing the request of User 1 and continues processing Request of User 2 because of which I am not getting same output in both the cases though the Input to Rules is same. If I do the process one after the another then I am getting correct values but it is not working for Concurrent execution. Thanks & Regards, Nikhil S. Kulkarni MASTEK LTD.
