[jboss-jira] [JBoss JIRA] Commented: (JBRULES-2358) ClassNotFoundException when using "mvel" as a dialect

ClassNotFoundException when using "mvel" as a dialect ----------------------------------------------------- Key: JBRULES-2358 URL: https://jira.jboss.org/jira/browse/JBRULES-2358 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 5.0.1.FINAL Environment: OS: Macos X and Linux JVM 1.6.0_15 from sun Reporter: stephane Brossier Assignee: Mark Proctor Attachments: Test.java I get a ClassNotFoundexception when using a very simple rule and test. The test dowloads a binary package from guvnor, containing one trivial rule. Then it creates a StatefulKnowledgeSession and insert 500 facts. The drl file uploaded on guvnor is: -------------------------- package mytest.debug.rules declare PerUserCount num : long profile : String end rule "Event" dialect "java" when e: PerUserCount() then System.out.println("Possible spammer [p=" + e.getProfile() + "] : count = " + e.getNum()); end ---------------------------- When calling fireAll, i get an exception. Note that: 1) The exception does not show up right away-- it only comes after some of those facts got processed 2) If i change the dialect from default 'mvel" to "java" it works fine: Exception in thread "main" java.lang.NoClassDefFoundError: mytest/debug/rules/PerUserCount at ASMAccessorImpl_7377369041259611028980.getValue(Unknown Source) at org.mvel2.optimizers.dynamic.DynamicGetAccessor.getValue(DynamicGetAccessor.java:66) at org.mvel2.ast.ASTNode.getReducedValueAccelerated(ASTNode.java:99) at org.mvel2.ast.BinaryOperation.getReducedValueAccelerated(BinaryOperation.java:102) at org.mvel2.ast.BinaryOperation.getReducedValueAccelerated(BinaryOperation.java:102) at org.mvel2.ast.BinaryOperation.getReducedValueAccelerated(BinaryOperation.java:102) at org.mvel2.compiler.ExecutableAccessor.getValue(ExecutableAccessor.java:41) at ASMAccessorImpl_7157329411259611028970.getValue(Unknown Source) at org.mvel2.optimizers.dynamic.DynamicGetAccessor.getValue(DynamicGetAccessor.java:66) at org.mvel2.ast.ASTNode.getReducedValueAccelerated(ASTNode.java:99) at org.mvel2.MVELRuntime.execute(MVELRuntime.java:85) at org.mvel2.compiler.CompiledExpression.getValue(CompiledExpression.java:107) at org.mvel2.MVEL.executeExpression(MVEL.java:978) at org.drools.base.mvel.MVELConsequence.evaluate(MVELConsequence.java:87) at org.drools.common.DefaultAgenda.fireActivation(DefaultAgenda.java:934) at org.drools.common.DefaultAgenda.fireNextItem(DefaultAgenda.java:885) at org.drools.common.DefaultAgenda.fireAllRules(DefaultAgenda.java:1086) at org.drools.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:660) at org.drools.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:627) at org.drools.impl.StatefulKnowledgeSessionImpl.fireAllRules(StatefulKnowledgeSessionImpl.java:183) at com.drools.debug.Test.runIteration(Test.java:132) at com.drools.debug.Test.startTest(Test.java:73) at com.drools.debug.Test.main(Test.java:196) Caused by: java.lang.ClassNotFoundException: mytest.debug.rules.PerUserCount at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:319) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:254) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:402) ... 23 more
