[rules-users] RuleAgent to KnowledgeAgent(org.drools.definition.rule.Rule to org.drools.rule.Rule)

Hi All, I want to convert org.drools.definition.rule.Rule to org.drools.rule.Rule,i.e i want to move RuleAgent to KnowledgeAgent. I tried: for( KnowledgePackage knowledgePackage: session.getKnowledgeBase().getKnowledgePackages() ) { for( Rule rule: knowledgePackage.getRules() ) { org.drools.rule.Rule odrRule = (org.drools.rule.Rule)rule; } } I get ClassCastException.Can anyone provide me with the solution/workaround. Thanks in advance. Regards, Kinjal
