[rules-users] KnowledgeAgent not reloading KnowledgeBase

[Pritam]

It's working now. The key was to provide a change-set location to
KnowledgeAgent and make the agent itself singleton in the app.

public static KnowledgeBase getKnowledgeBase()
    throws DroolsParserException, IOException {

    // hold a static reference in class
    if(agent != null) {
        return agent.getKnowledgeBase();
    }

    ResourceChangeScannerConfiguration sconf = 
       
ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration();      
    sconf.setProperty("drools.resource.scanner.interval", "5");

    ResourceFactory.getResourceChangeScannerService().configure(sconf);
    ResourceFactory.getResourceChangeScannerService().start();
    ResourceFactory.getResourceChangeNotifierService().start();

    agent = KnowledgeAgentFactory.newKnowledgeAgent("myagent");
   
agent.applyChangeSet(ResourceFactory.newFileResource("<path>\\change-set.xml"));

    return agent.getKnowledgeBase();

}


<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.xsd' >
   <add>
       <resource source='file:<path>/rules/' type='DRL' />
   </add>
 </change-set>
