[rules-users] Drools Dyanmic Class creation Problem

Hi sir , I am facing one issue regarding dyamic class cretion and inserting it's object into drools memory. i have created a dyanmic class test and loads it like that MyClassLoader clr =new MyClassLoader(Obj.getClass().getClassLoader()); Obj.clazz= clr.loadClass("test"); //Drools Configuration KnowledgeBuilderConfiguration kbc = KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration(null,clazz.getClassLoader()); KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(kbc); String path = System.getProperty("user.dir"); StringBuilder drlFile = new StringBuilder(path); drlFile.append(System.getProperty("file.separator")).append("myRule.drl"); kbuilder.add(ResourceFactory.newFileResource(drlFile.toString()), ResourceType.DRL); if (kbuilder.hasErrors()) { System.out.println(kbuilder.getErrors()); return; } KnowledgeBaseConfiguration kbaseConfig =KnowledgeBaseFactory.newKnowledgeBaseConfiguration(null, clazz.getClassLoader()); kbase = KnowledgeBaseFactory.newKnowledgeBase(kbaseConfig); kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()); ksession = kbase.newStatefulKnowledgeSession(); Now my drl file is like that package dyanmicclass; dialect "java" rule mytest1 when $tx : test($pp : name ) then globalArrayList.add($tx); System.out.println($tx ); end this is giving me a error KnowledgeBuilder created. Unable to generate rule invoker. : [Rule name='mytest1'] dyanmicclass/Rule_mytest1_0DefaultConsequenceInvoker.java (22:886) : test cannot be resolved to a type dyanmicclass/Rule_mytest1_0DefaultConsequenceInvoker.java (22:898) : test cannot be resolved to a type Rule Compilation error : [Rule name='mytest1'] dyanmicclass/Rule_mytest1_0.java (6:214) : txn cannot be resolved to a type but while i am doing like that dialect "java" rule mytest1 when $tx : test($pp : name ) then System.out.println($pp ); end it gives no error . I am not able to find the cause of the problem . am i wrong in any configuaration. Thanks Saurabh
