[rules-users] Problem using BRMS and Knowledge Agent

Hi all, I'm having problem getting the KnowledgeAgent and Guvnor working correctly... On the console I got this reports: 12:35:05,265 INFO [STDOUT] [2009:01:13 12:01:265:info] ResourceChangeScanner created with default interval=60 12:35:05,265 INFO [STDOUT] [2009:01:13 12:01:265:info] ResourceChangeScanner reconfigured with interval=30 12:35:06,468 INFO [STDOUT] [2009:01:13 12:01:468:info] ResourceChangeNotification created 12:35:06,468 INFO [STDOUT] [2009:01:13 12:01:468:debug] ResourceChangeNotification monitor added monitor=org.drools.io.impl.ResourceChangeScannerImpl@241eaf 12:35:06,468 INFO [STDOUT] [2009:01:13 12:01:468:debug] KnowledgeAgent building resource map 12:35:06,468 INFO [STDOUT] [2009:01:13 12:01:468:info] KnowledegAgent has started listening for ChangeSet notifications 12:35:06,468 INFO [STDOUT] [2009:01:13 12:01:468:info] KnowledgAgent created, with configuration: monitorChangeSetEvents=true scanResources=true scanDirectories=true 12:35:06,500 INFO [STDOUT] (null: 3, 88): schema_reference.4: Failed to read schema document 'drools-change-set-5.0.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>. 12:35:06,500 INFO [STDOUT] (null: 3, 88): cvc-elt.1: Cannot find the declaration of element 'change-set'. 12:35:06,500 INFO [STDOUT] (null: 4, 7): schema_reference.4: Failed to read schema document 'drools-change-set-5.0.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>. 12:35:06,500 INFO [STDOUT] (null: 7, 17): schema_reference.4: Failed to read schema document 'drools-change-set-5.0.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>. 12:35:06,500 INFO [STDOUT] [2009:01:13 12:01:500:info] KnowledgAgent applying ChangeSet 12:35:06,500 INFO [STDOUT] [2009:01:13 12:01:500:debug] KnowledgeAgent subscribing to resource=[UrlResource path='http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/regulation/regulation'] 12:35:06,500 INFO [STDOUT] [2009:01:13 12:01:500:debug] ResourceChangeNotification subscribing listener=org.drools.agent.impl.KnowledgeAgentImpl@1ca7c02 to resource=[UrlResource path='http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/regulation/regulation'] 12:35:06,500 INFO [STDOUT] [2009:01:13 12:01:500:debug] ResourceChangeScanner subcribing notifier=org.drools.io.impl.ResourceChangeNotifierImpl@939c8a to resource=[UrlResource path='http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/regulation/regulation'] 12:35:06,500 INFO [STDOUT] [2009:01:13 12:01:500:debug] KnowledgeAgent ChangeSet requires KnowledgeBuilder 12:35:06,500 INFO [STDOUT] [2009:01:13 12:01:500:debug] KnowledgeAgent rebuilding KnowledgeBase using ChangeSet 12:35:06,500 INFO [STDOUT] PackageName: regulation 12:35:06,500 INFO [STDOUT] PackageVersion: regulation 12:35:06,500 INFO [STDOUT] PackageIsLatest: false 12:35:06,500 INFO [STDOUT] PackageIsSource: false 12:35:06,515 INFO [STDOUT] PackageName: regulation 12:35:06,515 INFO [STDOUT] PackageVersion: regulation 12:35:06,515 INFO [STDOUT] PackageIsLatest: false 12:35:06,515 INFO [STDOUT] PackageIsSource: false 12:35:06,718 INFO [STDOUT] [2009:01:13 12:01:718:debug] KnowledgeAgent adding KnowledgeDefinitionsPackage regulation 12:35:06,843 INFO [STDOUT] [2009:01:13 12:01:843:debug] KnowledgeAgent building resource map ... as you can see, there is this line saying that it failed to read the schema-document. I don't know whether this could cause the problem I have right now: although a rule in the package regulation should fire (it is as easy as to check if "number < 5" then print out something), and I have indeed input a number smaller than 5, but it didn't. It also has those PackageIsLatest/PackageIsSource are "false" (how to get them set to true? at least for PackageIslatest) my code looks like this: public List<String> getViolatedRegulation(final List<Activity> activities ) { LOG.info("Checking rules ... "); final List<String> violatedRegulation = new ArrayList<String>(); this.ksession = this.getSession(); this.ksession.setGlobal("violatedRegulation", violatedRegulation); this.ksession.executeObject(new Object[] {activities}); return violatedRegulation; } (An activity object has an attribute "number": a rule checks whether the number < 5) private StatelessKnowledgeSession getSession() { LOG.info("Getting session for Rules Engine ..."); // Set the interval on the ResourceChangeScannerService if you are to use it // and default of 60s is not desirable. final ResourceChangeScannerConfiguration sconf = ResourceFactory.getResourceChangeScannerService() .newResourceChangeScannerConfiguration(); // set the disk scanning interval to 30s, default is 60s sconf.setProperty("drools.resource.scanner.interval", "30"); ResourceFactory.getResourceChangeScannerService().configure(sconf); this.kbase = KnowledgeBaseFactory.newKnowledgeBase(); final KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration(); // we want to scan directories, not just files, turning this on turns on file // scanning aconf.setProperty("drools.agent.scanDirectories", "true"); // resource changes results in a new instance of the KnowledgeBase being // built, this cannot currently be set to false for incremental building aconf.setProperty("drools.agent.newInstance", "true"); final KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("kagent", this.kbase, aconf); kagent.applyChangeSet(ResourceFactory.newFileResource("c:/changeset.xml")); return kagent.getKnowledgeBase().newStatelessKnowledgeSession(); } changeset.xml looks as follows: <change-set xmlns='http://drools.org/drools-5.0/change-set' xmlns:xs='http://www.w3.org/2001/XMLSchema-instance' xs:schemaLocation='http://drools.org/drools-5.0/change-set drools-change-set-5.0.xsd'> <add> <resource source='http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/regulation/regulation' type='PKG' /> </add> </change-set> Thanks for any explanation Regards Paul -- View this message in context: http://www.nabble.com/Problem-using-BRMS-and-Knowledge-Agent-tp21434310p2...
