[rules-users] having counter in drl

Hello, I would like to take 100 sampling facts for rule and persist it in the db and ignore other data. How Can I maintain the counter? as global variable? Please clarify with sample code. I tried following way and but it does not work as expected. Ex: global Integer counter; rule "get sampling data" when fact : Foo(some condition) && eval(counter <= 100) then counter++ // do some condition end -- View this message in context: http://www.nabble.com/having-counter-in-drl-tp20904469p20904469.html Sent from the drools - user mailing list archive at Nabble.com.
