My code is:
kbase= KnowledgeBaseFactory.newKnowledgeBase();
ksession= kbase.newStatefulKnowledgeSession();
aconf = KnowledgeAgentFactory .newKnowledgeAgentConfiguration();
aconf.setProperty("drools.agent.newInstance", "false");
kagent = KnowledgeAgentFactory.newKnowledgeAgent( "Agent", aconf);
kagent.applyChangeSet( ResourceFactory.newFileResource(filePath));
kbase = kagent.getKnowledgeBase();
ksession= kbase.newStatefulKnowledgeSession();
sconf
=ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration();
sconf.setProperty( "drools.resource.scanner.interval",
AgentContainerContext.getRuleReloadInterval() );
ResourceFactory.getResourceChangeScannerService().configure( sconf );
ResourceFactory.getResourceChangeNotifierService().start();
ResourceFactory.getResourceChangeScannerService().start();
Can any one help me to solve my problem?
Thanks & Regards
Annie
