Hi, I'm trying to use change-set.xml, which pionts to a drl file.My code is try { url =new URL("file:config/change-set.xml"); } catch (MalformedURLException e) { e.printStackTrace(); } kagent = KnowledgeAgentFactory.newKnowledgeAgent( "MyAgent" ); kagent.applyChangeSet( ResourceFactory.newUrlResource( url ) ); kbase = kagent.getKnowledgeBase(); ksession= kbase.newStatefulKnowledgeSession(); sconf =ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration(); sconf.setProperty( "drools.resource.scanner.interval", "10" ); ResourceFactory.getResourceChangeScannerService().configure( sconf ); ResourceFactory.getResourceChangeNotifierService().start(); ResourceFactory.getResourceChangeScannerService().start(); ksession.insert(object); ksession.fireAllRules(); and my change-set.xml is:- <?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 http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/... <add <resource source ='file:config/Rule.drl' type='DRL' basicAuthentication='enabled' username='admin' password='admin'></resource </add</change-set This code worked without any exception, but the rule is not executing. I tried without changeset.xml and rule worked properly. What is wrong? Thanks -- View this message in context: http://drools.46999.n3.nabble.com/Rule-not-working-with-Change-set-xml-tp...
