hi , i have the changeset file as below for scanning the directory of drl files. <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:/D:/users/myrules" type="DRL"/> </add> </change-set> Here, i have my agent configuration code. KnowledgeAgentConfiguration kaconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration(); kaconf.setProperty( "drools.agent.scanDirectories","true" ); kaconf.setProperty( "drools.agent.newInstance","false" ); kagent =KnowledgeAgentFactory.newKnowledgeAgent( "test agent", kaconf ); System.out.println("Before Applying ChangeSet"); kagent.applyChangeSet(ResourceFactory.newFileResource("D:/users/ChangeSet.xml")); System.out.println("After Applying Change Set"); ResourceChangeScannerConfiguration sconf = ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration(); sconf.setProperty("drools.resource.scanner.interval", "5"); ResourceFactory.getResourceChangeScannerService().configure(sconf); ResourceFactory.getResourceChangeNotifierService().start(); ResourceFactory.getResourceChangeScannerService().start(); It loads the drl files. But when i made changes to a drl file, it is not reflected. can anyone help me to find out the solution . thanks in advance.... -- View this message in context: http://drools.46999.n3.nabble.com/Changes-are-not-reflected-tp3917286p391...
