Re: [rules-users] Adding change/event listener to package

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 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. -W 2012/3/1 Jian Feng Ng <jng42(a)csc.com&gt;: > I saw many interfaces, but the problem is I do not know how to 'use' them. > Is there a tutorial or example codes somewhere? > > > > -----rules-users-bounces(a)lists.jboss.org wrote: ----- > > To: Rules Users List <rules-users(a)lists.jboss.org&gt; > From: Wolfgang Laun > Sent by: rules-users-bounces(a)lists.jboss.org > Date: 03/01/2012 04:38PM > Subject: Re: [rules-users] Adding change/event listener to package > > 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). > -W > > > > 2012/3/1 Jian Feng Ng <jng42(a)csc.com&gt; >> >> 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.
