See the javadoc on a lot of interfaces in org.drools.event.knowledgebase.
The expert manual has a section on the "Event Model" showing how to attach
a listener to the knowledge session (not a package).

I wish to add a listener to a package, so that my application can do
something else when there is any creation or deletion of rules in the
package. May I know how can I do this?

As with all Listeners in Java, you write a class implementing the methods
defined by the interface. The parameter types tell you about what is passed
to the respective call.
class Foo implements KnowledgeBaseEventListener {
public void afterRuleAdded(AfterRuleAddedEvent event){
if( "WatchedPackage".equals( event.getRule().getPackageName() ){
}
}
//...
}
A new Foo is attached to the kSession object - that's all.

I saw many interfaces, but the problem is I do not know how to
'use' them.
Is there a tutorial or example codes somewhere?

I tried but it doesn't seem to work. I am using UrlResource for
the
KnowledgeAgent.
kagent.getKnowledgeBase().addEventListener(new foo());
ResourceFactory.getResourceChangeNotifierService().start();
ResourceFactory.getResourceChangeScannerService().start();
But when the package is rescan, foo seems to be gone as kagent rebuilds
knowledgebase?
The Knowledge Agent builds a new Knowledge Base when resources change. You
should set up a listener for the Agent to detect KnowledgeBaseUpdatedEvent
and other Agent events.

Another approach is to subscribe to the package version feed, your
application will get notified when there is a change in the package.
Check this for details:
