Re: [rules-users] KnowledgeAgent Changeset problems

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!!!* -- View this message in context: http://drools.46999.n3.nabble.com/KnowledgeAgent-Changeset-problems-tp378...
