Thank you. :)
And how do I catch the exceptions occurring while processing and
executing the rules?
Hi,
If you are using 5.1 or greater, you can use
a KnowledgeAgentEventListener to be notified when resource's
compilation fails. You can create your own implementation
of KnowledgeAgentEventListener, or you can
use DefaultKnowledgeAgentEventListener and override just the methods
you need:
kagent.addEventListener(new DefaultKnowledgeAgentEventListener() {
public void
resourceCompilationFailed(ResourceCompilationFailedEvent event) {
//ResourceCompilationFailedEvent contains a reference to
kagent's kbuilder. You can use it to see what happened.
}
});
Best,

What's the best way for checking for errors when using the following
code for creating a kbase?
// ResourceChangeScanner
ResourceChangeScannerConfiguration sconf =
ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration();
sconf.setProperty("drools.resource.scanner.interval", "10");
ResourceFactory.getResourceChangeScannerService().configure(sconf);
ResourceFactory.getResourceChangeNotifierService().start();
ResourceFactory.getResourceChangeScannerService().start();
// knowledge base
KnowledgeBaseConfiguration kbaseConf =
KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
kbaseConf.setOption(EventProcessingOption.STREAM);
kbaseConf.setOption(MBeansOption.ENABLED);
KnowledgeBase kbase =
KnowledgeBaseFactory.newKnowledgeBase(kbaseConf);
// knowledge agent
KnowledgeAgentConfiguration kagentConf =
KnowledgeAgentFactory.newKnowledgeAgentConfiguration();
kagentConf.setProperty("drools.agent.newInstance", "false");
KnowledgeAgent kagent =
KnowledgeAgentFactory.newKnowledgeAgent("AITS CEP Engine Agent",
kbase,
kagentConf);
kagent.applyChangeSet(ResourceFactory.newClassPathResource(myFile));
// session
fSession = kbase.newStatefulKnowledgeSession();
Thank you.
