[rules-users] Problem in Concurrent execution of Rules

[Nikhil S. Kulkarni]

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
