Could you append the log output of the Knowledge Agent?

Thank you every body for your answer, unfortunately I was't able to reply to
you until now because other stuff overwhelmed me literally at work.
Anyway I was going ahead using KnowledgeAgent, following your comments and
other suggestion. Now I am able to load rules applying change set with
KnowledgeAgent (thank you!!!), but honestly this is a poor success because,
even if when I change the rule KnowledgeAgent says "incremental build of
KnowledgeBase finished and in use" nothing changes.
It seems that changes at rules have no effect and it is pretty weird. I made
a maven project with eclipse to explain you better my problem. Is a simple
main. I am working for a better junit test. Anyway if you change the rule in
the folder knowledge you can test the problem by yourself.
Briefly I will explain the project:

Here the code:

               _l.warn("START");
               String xml = "";
               xml += "<change-set xmlns='http://drools.org/drools-5.0/change-set'&quot;;
               xml += &quot;
xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'&quot;;
               xml += &quot;
xs:schemaLocation='http://drools.org/drools-5.0/change-set
drools-change-set-5.0.xsd' >";
               xml += "    <add> ";
               xml += "        <resource source='Z:/EXP/drools-test/knowledge/test.drl'
type='DRL' />";
               xml += "    </add> ";
               xml += "</change-set>";
               FileManager fileManager = new FileManager();
               File fxml = fileManager.newFile("changeset.xml");
               Writer output = new BufferedWriter(new FileWriter(fxml));
               output.write(xml);
               output.close();
               // build a KnowledgeAgent
               ResourceFactory.getResourceChangeNotifierService()
                                               .start();
               ResourceFactory.getResourceChangeScannerService()
                                               .start();

               final ResourceChangeScannerConfiguration sconf =
ResourceFactory.getResourceChangeScannerService()
                                                                                                                                               .newResourceChangeScannerConfiguration();
               sconf.setProperty("drools.resource.scanner.interval", "2");
               ResourceFactory.getResourceChangeScannerService()
                                               .configure(sconf);

               final KnowledgeAgentConfiguration aconf =
KnowledgeAgentFactory.newKnowledgeAgentConfiguration();
               aconf.setProperty("drools.agent.scanDirectories", "true");
               aconf.setProperty("drools.agent.scanResources", "true");
               /*
                * important newInstance has to be false in order to update the
                * knowledge base and not rebuild a new one
                */
               aconf.setProperty("drools.agent.newInstance", "false");
               final KnowledgeAgent agent =
KnowledgeAgentFactory.newKnowledgeAgent("pch.sel.knowledge.agent", aconf);
               // if (_l.isDebugEnabled()) {
               /* we need some log every time */
               agent.setSystemEventListener(new PrintStreamSystemEventListener());

agent.applyChangeSet(ResourceFactory.newClassPathResource("pch.sel.kwset.xml"));
               // fire rules
               StatefulKnowledgeSession session =
agent.getKnowledgeBase().newStatefulKnowledgeSession();
               session.fireAllRules();
               _l.warn("END");


and here the rule


package it.ipiu.drools.KnowledgeAgent.test

rule "test rule" timer(int: 0s 2s)
   when
       eval(true);
   then
           System.out.println("ciao");
end



If I try to change timer from 2s to 2m nothing changes even if
KnowledgeAgent seems to reload all.

*Please help!!! I googled the problem everywhere without solution!!!*
