[rules-users] Complicated Issue
hey, M using guvnor 5.3.0 Final version and two instances of guvnor. In my first guvnor application, i ve two packages containg all my rules which i am accessing using drools core and knowledge api v5.2.0 Final .I use type DRL to extract rules from my change set. In my second guvnor application, i just have a package which contains my JBPM process. Here, i am using drools 5.3.1 Final jars to connect and make my kbase. i use type = PKG in my chnage set, which is contradictory to JIRA https://issues.jboss.org/browse/JBRULES-3388 is opened that a PKG cannot be read, but was working fine for my application. Now i dont want to deploy two different wars of guvnor and was expecting to do it by deploying just 1 guvnor. So instead of taking the headache of using different jars, i used a neutral GUVNOR and drools 5.4.0 final version. I deployed the guvnor, imported the old repository, built the packages and tried firing the rules using type = DRL in my change set. Everything Worked fine. As soon as i changed my type = PKG in my change set to access the rules, i got an error : java.lang.UnsupportedClassVersionError: Institutional/CalculateDateDifference : Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:620) at org.drools.rule.JavaDialectRuntimeData$PackageClassLoader.fastFindClass(JavaDialectRuntimeData.java:615) at org.drools.util.CompositeClassLoader$CachingLoader.load(CompositeClassLoader.java:254) at org.drools.util.CompositeClassLoader$CachingLoader.load(CompositeClassLoader.java:237) at org.drools.util.CompositeClassLoader.loadClass(CompositeClassLoader.java:88) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at org.drools.rule.MVELDialectRuntimeData.getParserConfiguration(MVELDialectRuntimeData.java:270) at org.drools.base.mvel.MVELCompilationUnit.getCompiledExpression(MVELCompilationUnit.java:203) at org.drools.base.mvel.MVELConsequence.compile(MVELConsequence.java:75) at org.drools.rule.MVELDialectRuntimeData.onBeforeExecute(MVELDialectRuntimeData.java:173) at org.drools.rule.DialectRuntimeRegistry.onBeforeExecute(DialectRuntimeRegistry.java:144) at org.drools.common.AbstractRuleBase.addPackages(AbstractRuleBase.java:599) at org.drools.reteoo.ReteooRuleBase.addPackages(ReteooRuleBase.java:472) at org.drools.impl.KnowledgeBaseImpl.addKnowledgePackages(KnowledgeBaseImpl.java:150) at org.drools.agent.impl.KnowledgeAgentImpl.addResourcesToKnowledgeBase(KnowledgeAgentImpl.java:1085) at org.drools.agent.impl.KnowledgeAgentImpl.rebuildResources(KnowledgeAgentImpl.java:824) at org.drools.agent.impl.KnowledgeAgentImpl.buildKnowledgeBase(KnowledgeAgentImpl.java:673) at org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:203) at org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:182) at com.infy.fcs.drools.adapter.DroolsGuvnorTest.readKnowledgeBase(DroolsGuvnorTest.java:196) at com.infy.fcs.drools.adapter.DroolsGuvnorTest.main(DroolsGuvnorTest.java:107) When i tried to access the process package(Which is a diff package and contains only a process), i got the following error java.lang.UnsupportedClassVersionError: Fatca_Process/Process_Fatca_Process_Fatca_integration_queue_f06d3a378a5f49d5b7589aae2c0b686eReturnValueEvaluator7Invoker : Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:620) at org.drools.rule.JavaDialectRuntimeData$PackageClassLoader.fastFindClass(JavaDialectRuntimeData.java:615) at org.drools.util.CompositeClassLoader$CachingLoader.load(CompositeClassLoader.java:254) at org.drools.util.CompositeClassLoader$CachingLoader.load(CompositeClassLoader.java:237) at org.drools.util.CompositeClassLoader.loadClass(CompositeClassLoader.java:88) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at org.drools.rule.JavaDialectRuntimeData.wire(JavaDialectRuntimeData.java:435) at org.drools.rule.JavaDialectRuntimeData.wire(JavaDialectRuntimeData.java:430) at org.drools.rule.JavaDialectRuntimeData.onBeforeExecute(JavaDialectRuntimeData.java:256) at org.drools.rule.DialectRuntimeRegistry.onBeforeExecute(DialectRuntimeRegistry.java:138) at org.drools.common.AbstractRuleBase.addPackages(AbstractRuleBase.java:599) at org.drools.reteoo.ReteooRuleBase.addPackages(ReteooRuleBase.java:472) at org.drools.impl.KnowledgeBaseImpl.addKnowledgePackages(KnowledgeBaseImpl.java:150) at org.drools.agent.impl.KnowledgeAgentImpl.addResourcesToKnowledgeBase(KnowledgeAgentImpl.java:1085) at

Guvnor 5.4 needs Java 1.6. http://docs.jboss.org/drools/release/5.5.0.Beta1/droolsjbpm-introduction-docs/html/releaseNotes.html#releaseNotes_5.4.0 Guvnor 5.4.x requires at least Java 6 to run.

[rules-users] Finding the definition of a rule
Hi, I am currently using a KnowledgeAgent to implement hot deployment in our applications. So far this is working, but now the requirement arose to remove specific rules via program call. I thought the easiest way would be to remove the rule from the resources and let the KnowledgeAgent handle the rest. But as far as I see, there is no way to get the source resource of a rule from the KnowledgeBase/RuleBase. I guess I wont have another choice than to parse the initial changeset, gather all resources, and go through them to find and remove the rule. But this seems like overkill to achieve something that simple. Does anybody know a better way to remove specific rules while using a KnowledgeAgent. kind regards Lukas -- View this message in context: http://drools.46999.n3.nabble.com/Finding-the-definition-of-a-rule-tp4020183.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Finding the definition of a rule
org.drools.rule.Rule has a getResource() method, set during the build process, that is not publicly reflected by the org.drools.definition.rule.Rule interface. Iterating over knowledgeAgent.getKnowledgeBase().getKnowledgePackage(xyz).getRules() with a type check and a cast should do the trick. Maybe Mark can tell if it would be appropriate to expose it or not.
