Hello everyone, I recently started using Drools Guvnor and i find it necessary. I create rules on Guvnor and fire the rules in a Java application and everything is fine. However when i try to access the rules in a GWT application,i get an error which looks like none of the Drools code is executed. My request is if any one has used rules n a GWT application please help me out -- Moses Kalema Bachelor Science in Computer Engineering Software/Mobile/Embedded Systems Developer +256773391723 +256704209937 Skype: mkgremo Twitter: @mkgremo "Life's Success is based on Opportunity not Chance" _______________________________________________ rules-dev mailing list rules-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-dev

In my serviceImplementation[in the server package] class in GWT RPC When i try to check the execution the system doesn't run this line: KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); //inputStream = this.getClass().getClassLoader().getResourceAsStream("ChangeSet.xml"); url= this.getClass().getClassLoader().getResource("ChangeSet.xml"); workingDirectory = System.getProperty("user.dir"); System.out.println("URL "+url); file = new File(workingDirectory +"/src/ChangeSet.xml"); if(file.exists()){ System.out.println("Directory "+file.getName()); } else{ System.out.println("File not seen"); } kbuilder.add( ResourceFactory.newUrlResource(url),ResourceType.CHANGE_SET); if( kbuilder.hasErrors() ) { System.out.println( kbuilder.getErrors() ); System.out.println("The changeset file has errors"); // return; }else{ System.out.println("The changeset has no errors"); } KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); System.out.println("knowledgebase has been created"); KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent( "MyAgent" ); // URL url = getClass().getResource("ChangeSet.xml"); // File file = new File(url.getPath()); kagent.applyChangeSet( ResourceFactory.newUrlResource(url) ); kbase = kagent.getKnowledgeBase(); ResourceFactory.getResourceChangeNotifierService().start(); ResourceFactory.getResourceChangeScannerService().start(); System.out.println("knowledge agent created"); StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); System.out.println("session created"); FactType factType = kbase.getFactType("procnet.requisition.test", "requisition"); try { Object obj = factType.newInstance(); factType.set(obj, "requisitionType", requisitionType); factType.set(obj, "totalCost", totalCost); FactHandle objHandle = ksession.insert(obj); ksession.fireAllRules(); System.out.println(factType.get(obj, "approvalMessage")); approvalMessage = (String) factType.get(obj, "approvalMessage"); //System.out.println(factType.get(obj, "name")); } catch (InstantiationException e) { e.printStackTrace(); } catch (IllegalAccessException e) { e.printStackTrace(); } return approvalMessage; This is the exact code i use in a normal java application and it works fine,infact even when i run the class as a java application it returns the approve message from guvnor.
