[rules-users] auto-loading of rules from dir using Know Agent (Drools 5)

[nadeem mehmood]

Hello,
I am new to drools and trying to work with the knowledge agent for the automatic loading of rules into the knowledge base from a directory and then firing all the rules. Am using the ChangeSet xml File to configure the rule directory. Actually the problem is: the rules are fired for the first time only, but when I put a new rule file in the directory the new rules does't fire.
plz find the source code in the attachment

MY CODE:public class KnowAgent {	KnowledgeBase buildKBA(KnowledgeBase kb){		KnowledgeAgent kagent =
 KnowledgeAgentFactory.newKnowledgeAgent( "MyAgent" );		
				kagent.applyChangeSet( ResourceFactory.newClassPathResource("resChangeSet.xml") );				ResourceFactory.getResourceChangeNotifierService().start();		ResourceFactory.getResourceChangeScannerService().start();		kb = kagent.getKnowledgeBase();		return kb;
	}}--------------------------------------------------public class RuleRunnerKnowledgeAgent {	private KnowAgent myKnowAgent = new KnowAgent();	private KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();	private KnowledgeRuntimeLogger logger;	private StatefulKnowledgeSession ksession;
    public void RuleRunnerKnowledgeAgent(String[] rules,                         Object[] facts) throws Exception {        kbase = myKnowAgent.buildKBA(kbase);      
          ksession = kbase.newStatefulKnowledgeSession();        logger = KnowledgeRuntimeLoggerFactory.newFileLogger(ksession, "agentkblog");        ksession.fireAllRules();    }}--------------------------------------------------<?xml version="1.0" encoding="utf-8"?><change-set xmlns='http://drools.org/drools-5.0/change-set'             xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'             xs:schemaLocation='http://drools.org/drools-5.0/change-set drools-change-set-5.0.xsd' >   <add>      <resource source='file:src/main/rules/org/drools/prepare/collection/' type='DRL'
