[rules-users] Integrating rules with your applications +Changeset.xml

[HonorGod]

Something like this is working for me -

private StatefulKnowledgeSession getSession() {
        
        LogUtil.decisionLogger.info("Getting session for Rules Engine ...");
        // Set the interval on the ResourceChangeScannerService if you are
to use it
        // and default of 60s is not desirable.
        final ResourceChangeScannerConfiguration sconf =
ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration();
        // set the disk scanning interval to 30s, default is 60s
        sconf.setProperty("drools.resource.scanner.interval", "30");

        ResourceFactory.getResourceChangeScannerService().configure(sconf);

        knowledgeBaseFromDecisionTable =
KnowledgeBaseFactory.newKnowledgeBase();

        final KnowledgeAgentConfiguration aconf =
KnowledgeAgentFactory.newKnowledgeAgentConfiguration();
        // we want to scan directories, not just files, turning this on
turns on file
        // scanning
        aconf.setProperty("drools.agent.scanDirectories", "true");
        // resource changes results in a new instance of the KnowledgeBase
being
        // built, this cannot currently be set to false for incremental
building
        aconf.setProperty("drools.agent.newInstance", "true");

        final KnowledgeAgent kagent =
KnowledgeAgentFactory.newKnowledgeAgent("kagent",
knowledgeBaseFromDecisionTable, aconf);
       
kagent.applyChangeSet(ResourceFactory.newClassPathResource("ChangeSet.xml"));
       
//kagent.applyChangeSet(ResourceFactory.newFileResource("c:/changeset.xml"));
        return kagent.getKnowledgeBase().newStatefulKnowledgeSession();

    }
