Hi, i am using Guvnor-5.2.0 . Through a simple java client class i wanted to add a rule at runtime. below is the snippet of java code i am using to add a rule. KnowledgeBase knowledgeBase = createKnowledgeBase(); session = knowledgeBase.newStatefulKnowledgeSession(); logger = KnowledgeRuntimeLoggerFactory.newFileLogger(session, "log/DroolsSample"); KnowledgeRuntimeLoggerFactory.newConsoleLogger(session); String ruleDescription = "package com.tcube.atyaf.dto;"+ "import com.tcube.atyaf.dto.EmployeeDataDTO;" + "rule \"SimpleDRLRule\""+ " @ID(11003588)"+ " lock-on-active true"+ " salience -11"+ " dialect 'mvel'"+ " when m : EmployeeDataDTO(empName==\"PC\");"+ " then System.out.println( \"*************rule executed\");" + " m.setDesignation( \"Manager ,Additional Duties & Additional hike !!!\" );"+ " update( m );"+ " end"; byte[] data = ruleDescription.getBytes(); KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(knowledgeBase); kbuilder.add( ResourceFactory.newClassPathResource("ChangeSet.xml"), ResourceType.CHANGE_SET ); kbuilder.add( ResourceFactory.newClassPathResource("TestRule.drl"), ResourceType.DRL); kbuilder.add(ResourceFactory.newByteArrayResource(data), ResourceType.DRL); if(kbuilder.hasErrors()) { System.out.println( kbuilder.getErrors() ); return; } Collection<KnowledgePackage> kpkgs = kbuilder.getKnowledgePackages(); knowledgeBase.addKnowledgePackages( kpkgs ); emp = new EmployeeDataDTO(); emp.setEmpNo(1); emp.setEmpName("PC"); emp.setAge(29); emp.setSalary(new BigDecimal("6500")); session.insert(emp); session.fireAllRules(); I am getting all the rules executed as per exceptation since it is in the same session, however the new rules that i have added are not reflected in Drools-Guvnor UI.... please help me on code for deploying the knowldgeBase/Package(kpkgs) to Drools-Guvnor UI.. ----- PC -- View this message in context: http://drools.46999.n3.nabble.com/facing-problems-while-adding-a-Rule-to-...
