Problem add DSL,add more than one file to Ruleagent

Hi ,

    I am having problem to add DSL to rule agent . How to add DSL , I can add dsl using PackageBuilder.addPackageFromDrl("x.drl","y.dsl")  cant take this approach since,
we are using standalone application not using BRMS want to update new rules so i am using RuleAgent and passing properties.
But unable to add Dsl to the ruleagent and another problem unable to add more than one drl files.
Please provide some example else some ideas are helpful.

Code :


              Properties dynamicRueProperties = new Properties();
                dynamicRueProperties.setProperty("name", "SampleRuleAgent");
                dynamicRueProperties.setProperty("dir", "C:/Project/Workspace/DroolsTest/rules");
                dynamicRueProperties.setProperty("file", C:/Project/Workspace/DroolsTest/rules/file.drl");
                dynamicRueProperties.setProperty("localCacheDir", "C:/Project/Workspace/DroolsTest/dump");
                dynamicRueProperties.setProperty("poll", "30");
                dynamicRueProperties.setProperty("newInstance", "false");
RuleBase ruleBase = null;
RuleAgent ruleAgent = null;
ruleAgent = RuleAgent.newRuleAgent(ruleProperties);


Thanks & Regards
