Hello, I'm a newbie to drools. I would like to know why i get the following output on the console : Test Message found!! No strange message :-) Test Message found!! Test Message found!! NotifyEngineTest.java creates 10 events. Rule "test2" should be activated with every event, so that the output should look like this: Test Message found!! No strange message :-) Test Message found!! No strange message :-) Test Message found!! No strange message :-) Could somebody help me with this ? I appriciate your help Thanks in advance, Anna // NotifyEngineTest.java// for (int i = 0; i < 10; i++){ Event e = new Event(); e.setId("ID"+Math.random()); e.setTimestamp(new Date()); e.setCatagory("TEST"); e.setMessage( i + " Test"); e.setSystem("localhost"); ruleEngine.insert(e); _____________________________________________________________________ // RuleEngine.java// public void insert(Event e) throws RuleEngineException { FactHandle factHandle = ksession.insert(e); int numberOfRules = ksession.fireAllRules(); logger.debug("Rules fired: "+numberOfRules); } ______________________________________________________________________ // Notify.drl// rule "test" salience 10 when $r: Event(message matches ".*Test.*") then System.out.println("Test Message found!! "+ $r); end rule "test2" salience 5 when not ( Event( (system == "anySystem" && catagory == "anyCatagory" ) || (system == "anyHost" && message matches ".*Hello.*"))) then System.out.println(" No strange message :-) "); end ____________________________________________________________________ -- View this message in context: http://drools.46999.n3.nabble.com/Multiple-Insert-and-negative-rule-tp353...
