Re: [rules-users] java.lang.ClassCastException: [Lorg.drools.rule.Package; cannot be cast to org.drools.rule.Package

Hi, Thanks for your reply. Now the mentioned error is not coming, but I am not able to fetch packages stored in guvnor. I have following updated code: *KnowledgeAgent agent = KnowledgeAgentFactory.newKnowledgeAgent("/com/model/drools.properties"); KnowledgeBase ruleBase = agent.getKnowledgeBase(); StatefulKnowledgeSession workingMemory = ruleBase.newStatefulKnowledgeSession(); StaffSO staff = new StaffSO(); staff.setDept("YO"); staff.setUser("User"); workingMemory.insert(staff); System.out.println("number of facts " + workingMemory.getFactHandles().size()); workingMemory.fireAllRules(new RuleNameEndsWithAgendaFilter("UI_Kunde")); System.out.println("after fire rules ,number of facts " + workingMemory.getFactHandles().size()); for(Iterator i=workingMemory.getObjects().iterator();i.hasNext();){ System.out.println(((StaffSO)i.next()).getEditableFields()); }* Thanks, Manasi. -- View this message in context: http://drools.46999.n3.nabble.com/java-lang-ClassCastException-Lorg-drool...
