[rules-users] Getting a Drools Fusion - CEP Example to work

Hello I have built my first few test rules and now I'm working on moving on to more complex questions. Since I need to monitor data over time I would like to lern from the example provided here: http://javabeans.asia/articles/drools_5_case_study_2_complex_event_proces... Unfortunately I can't get the tutorial to work properly. In eclipse I have the error marker ---------------------- Description Resource Path Location Type Error: java.lang.NullPointerException account.drl /SlidingWindowCEP/etc Unknown Drools Error ---------------------- and upon build and get following error: ---------------------- [81,20]: [ERR 101] Line 81:20 no viable alternative at input '90d' in rule "NinetyDaysPeriod" java.lang.IllegalArgumentException: Could not parse knowledge. at net.javabeansdotasia.casestudy.test.Tester.prepareKnowledgeBase(Tester.java:85) at net.javabeansdotasia.casestudy.test.Tester.setUp(Tester.java:54) at net.javabeansdotasia.casestudy.test.Tester.main(Tester.java:118) java.lang.NullPointerException at net.javabeansdotasia.casestudy.test.Tester.prepareAccountInfo(Tester.java:98) at net.javabeansdotasia.casestudy.test.Tester.setUp(Tester.java:55) at net.javabeansdotasia.casestudy.test.Tester.main(Tester.java:118) Exception in thread "main" java.lang.NullPointerException at net.javabeansdotasia.casestudy.test.Tester.prepareStatefulKnowledgeSession(Tester.java:70) at net.javabeansdotasia.casestudy.test.Tester.setUp(Tester.java:56) at net.javabeansdotasia.casestudy.test.Tester.main(Tester.java:118) ---------------------- Now if I change 90d to 90m the Nullpointer Error goes away but then two new markers appear at rule "NinetyDaysPeriod" and rule "FiveLastClaims": ---------------------- Description Resource Path Location Type BuildError: Unable to build expression for 'consequence': [Error: Failed to compile: 1 compilation error(s): - (4,31) unable to resolve method using strict-mode: java.lang.Object.setEligibleForBonusClaims(java.lang.Boolean)] [Near : {... Unknown ....}] ^ [Line: 1, Column: 0] ' modify($accountInfo) { setAveOfLastClaims($aveOfLastClaims); setEligibleForBonusClaims(true); }; ' account.drl /SlidingWindowCEP/etc line 21 Drools Error ---------------------- Description Resource Path Location Type BuildError: Unable to build expression for 'consequence': [Error: Failed to compile: 1 compilation error(s): - (4,33) unable to resolve method using strict-mode: java.lang.Object.setEligibleForPeriodicBonus(java.lang.Boolean)] [Near : {... Unknown ....}] ^ [Line: 1, Column: 0] ' modify($accountInfo) { setAveForPeriod($aveForPeriod); setEligibleForPeriodicBonus(true); }; ' account.drl /SlidingWindowCEP/etc line 65 Drools Error ---------------------- I'm using Drools 5.1 and JDK 1.6 the tutorial is based upon 5.0 and JDK 1.5 could that be the root of my problem? I'm stuck here and still in the process of learning Java so any hint is appreciated. -- View this message in context: http://drools.46999.n3.nabble.com/Getting-a-Drools-Fusion-CEP-Example-to-...
