[rules-users] Programatically adding rules to KnowledgeBase/StatefulKnowledgeSession

Hello all, I'm trying to add rules through my java code to a KnowledgeBase and I cannot find any easy way to do so. So far, the only solution I could think of, is to write the rule as DRL in a file that is "observed" by a KnowledgeAgent (same with a RuleAgent I suppose). Is it possible to create a new KnowledgePackage with the same name as the existing one and load it into the KnowledgeBuilder? I manage to remove rules using the following code: statefulKnowledgeSession.getKnowledgeBase().removeRule(knowledgeSetName, ruleName); I thought that there would be a addRule method somewhere but not luck so far. The code I'm using to create my KnowledgeBase and StatefulKnowledgeSession is shown below. All the best, Pierre StatefulKnowledgeSession creation code: StatefulKnowledgeSession ksession; KnowledgeBuilder kbuilder; KnowledgeBase kbase; kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add(ResourceFactory.newFileResource(Demo.class.getResource(Demo.drl File).getPath()), ResourceType.DRL); if (kbuilder.hasErrors()) { System.out.println(kbuilder.getErrors()); } kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()); ksession = kbase.newStatefulKnowledgeSession(); ksession.insert(.); . ksession.fireAllRules();
