Hi, I have written the next rule : rule "Too many events in a short period of time" dialect "mvel" when $user : User() Number(intValue > 3) from accumulate($event : Event(userId == $user.id) over window:time(1m) from entry-point Event , count($event)) then //Java code... end And the events, I insert in the Event entrypoint, are 4 and have these timestamps: Calendar cal1 = Calendar.getInstance(); cal1.set(2010,9,23,10,30,00); Calendar cal2 = Calendar.getInstance(); cal2.set(2010,9,23,10,30,05); Calendar cal3 = Calendar.getInstance(); cal3.set(2010,9,23,10,30,10); Calendar cal4 = Calendar.getInstance(); cal4.set(2010,9,23,10,30,15); Has the rule any syntax or semantic problem, knowing that i aim to catch if there has been more than 3 events in the last minute? -- Nicolás Sanchez _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

About the questions you asked, here are the answers: - Is Event declared properly in the DRL? Yes, it's been declared properly - Is the session run properly? Yes - Is the insert call correct? Yes What I forgot to mention, and excuse me for that omission, is that this Event is declared inside the DRL file, there is no java class in the packages. This is the declare I have written: declare BankEvent @role(event) @timestamp(callDateTime.getTime()) @duration(callDuration) userId : String sequentialID : long transactionID : long opCode : long amount : int callDateTime : Date callDuration : long end I think the problem is with operator "over window:time(1m)" because if remove it, rule "Too many events in a short period of time" dialect "mvel" when $user : User() Number(intValue > 3) from accumulate($event : Event(userId == $user.id) from entry-point Event , count($event)) then //Java code... end the rule fires... -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-Agregate-function-count-the...

I have just tried it, but it doesn't fire. What is odd is that I have other rules, in the same drl, with time operators such as after[] and they work perfectly ok when using the @timestamp(callDateTime.getTime()) or @timestamp(callDateTime).
