Try a version range or a SNAPSHOT. LATEST doesn't work in 6.0.1 for the scanner. -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of SrjTx Sent: Wednesday, March 26, 2014 2:27 PM To: rules-users(a)lists.jboss.org Subject: [rules-users] 6.0.1.F Need help in getting recanned rules into new session I've have been unable to figure out how to get drools to rescan and then use the updated rules in a new session. I currently have to restart jboss to pick up the changes. The scanning seems to happen, but I don't see the changes that should be included. I have looked at lots of example code on the web and also at the Switchyard source. When I do this in tandem with SY, I can get it to work, but I need/want to have it work on its own. I have tried some different combinations with no luck. In addition to the "why doesn't it work", I would like to clearly understand: Do I need a KieBase, or should I just be creating sessions off of the container? What do I need to have in Envinonment?. What do I need to have in ksessionConfiguration? Related, what is the proper mechanism to pass in the Session Name? GAD is: com.xyz.policy, cep, 1.0 Drools session is stateful and named "DroolsSession", stream processing mode, realtime I initialized KIE with the following. kieServices = KieServices.Factory.get(); releaseId = kieServices.newReleaseId("com.xyz.policy", "cep", "LATEST"); kieFileSystem = kieServices.newKieFileSystem().generateAndWritePomXML( releaseId); kieBuilder = kieServices.newKieBuilder(kieFileSystem); kieBuilder.buildAll(); Results results = kieBuilder.getResults(); if (results.hasMessages(Message.Level.ERROR)) { StringBuilder sb = new StringBuilder(); for (Message message : results.getMessages(Message.Level.ERROR)) { if (sb.length() != 0) { sb.append(" -- "); } sb.append(message.toString().trim()); } log("Unable to initialize KIE " + sb.toString()); } else { env = kieServices.newEnvironment(); kieContainer = kieServices.newKieContainer(releaseId); kieScanner = kieServices.newKieScanner(kieContainer); kieBaseConfiguration = kieServices.newKieBaseConfiguration(); kieBase = kieContainer.newKieBase(kieBaseConfiguration); kieSessionConfiguration = kieServices.newKieSessionConfiguration(); kieSessionConfiguration.setProperty("sessionName", "DroolsSession"); kieSessionConfiguration.setProperty("drools.clockType", "realtime"); kieSessionConfiguration.setProperty("drools.evenProcessingMode", "stream"); Later when I determine it is time to rescan, I do the following: kieScanner.scanNow(); System.err.println("Scanning..."); currentKieSessionThread = new KieSessionThread( kieBase.newKieSession(kieSessionConfiguration, env)); executorBean.execute(currentKieSessionThread); -- View this message in context: http://drools.46999.n3.nabble.com/6-0-1-F-Need-help-in-getting-recanned-r...

I haven't tried ranges myself. I know for sure SNAPSHOTS work. I think you may need a bracket at the end of your range definitions. Like: releaseId = kieServices.newReleaseId("com.xyz.policy","cep", "[1.0-10.0]"); -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of SrjTx Sent: Wednesday, March 26, 2014 3:47 PM To: rules-users(a)lists.jboss.org Subject: Re: [rules-users] 6.0.1.F Need help in getting recanned rules into new session Could you please give me an example of the ranges?
