Re: [rules-users] DRL package builder or rule base error

Thanks everybody for the responses. Scanning through old posts here, I found out that each time a new DRL is added to package builder, all the rules from the previous DRL are also compiled again. So, that means, the rules in the first DRL will compile 3 times unnecessarily. So, I'm going to put all rules in just one drl. If anybody wishes to see mor details then check out the end of this thread where this behaviour has been discussed......plz look towards the end. http://www.nabble.com/RuleBase-addPackage-failure-td6603598.html#a6607165 I noticed that when I chaged the name of some rules then I started getting null pointer exception with this stack trace. java.lang.NullPointerException at org.drools.reteoo.ReteooBuilder.removeRule(ReteooBuilder.java:224) at org.drools.reteoo.ReteooRuleBase.removeRule(ReteooRuleBase.java:270) at org.drools.common.AbstractRuleBase.removeRule(AbstractRuleBase.java:656) at org.drools.common.AbstractRuleBase.mergePackage(AbstractRuleBase.java:519) at org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:409) at com.uhg.scs.optum.ng.rules.RuleEngine.parseRuleFiles(RuleEngine.java:102) at com.uhg.scs.optum.ng.rules.RuleEngine.<clinit>(RuleEngine.java:46) at com.uhg.scs.optum.ng.unittest.HaRulesOldUnitTests.<init>(HaRulesOldUnitTests.java:20) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at junit.framework.TestSuite.createTest(TestSuite.java:61) at junit.framework.TestSuite.addTestMethod(TestSuite.java:283) at junit.framework.TestSuite.<init>(TestSuite.java:146) at org.junit.internal.runners.JUnit38ClassRunner.<init>(JUnit38ClassRunner.java:67) at org.junit.internal.builders.JUnit3Builder.runnerForClass(JUnit3Builder.java:14) at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:57) at org.junit.internal.builders.AllDefaultPossibilitiesBuilder.runnerForClass(AllDefaultPossibilitiesBuilder.java:29) at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:57) at org.junit.internal.requests.ClassRequest.getRunner(ClassRequest.java:24) Guessing ....that removing/renaming rules must proceed with some clean up first...anybody has any idea how to cleanly do that?? -- View this message in context: http://www.nabble.com/DRL-package-builder-or-rule-base-error-tp20627083p2...
