[rules-users] newbie: getWorkingMemoryEntryPoint returns NULL

Hello, I've got the following basic code that sets up drools in STREAM mode, with a pseudo clock. And it fails on the last line that asserts there is an entrypoint named "testEntryPoint". The DRL file references the entry-point which according to the documentation is enough. What am I missing? Itai declare Message @role(event) @timestamp(timestamp) end declare AppInfo @role(event) @timestamp(timestamp) end rule "Change message type after one minute" dialect "mvel" when $appinfo:AppInfo() from entry-point "testEntryPoint" $message:Message( type == "before", $msgtext : msgtext, this after[ 1m ] $appinfo ) from entry-point "testEntryPoint" then System.out.println( $msgtext ); modify ( $message ) { type = "after" } end private void initDrools() { KnowledgeBaseConfiguration config = KnowledgeBaseFactory.newKnowledgeBaseConfiguration(); // Stream mode allows interacting with the clock (Drools Fusion) config.setOption(EventProcessingOption.STREAM); kbase = KnowledgeBaseFactory.newKnowledgeBase(config); kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); // this will parse and compile in one step kbuilder.add(ResourceFactory.newClassPathResource(RULE_FILE, DroolsExpertTest.class), ResourceType.DRL); // Check the builder for errors assertThat(kbuilder.hasErrors()) .overridingErrorMessage(kbuilder.getErrors().toString()) .isFalse(); // get the compiled packages (which are serializable) Collection<KnowledgePackage> pkgs = kbuilder.getKnowledgePackages(); // add the packages to a knowledgebase (deploy the knowledge packages). kbase.addKnowledgePackages(pkgs); KnowledgeSessionConfiguration conf = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(); conf.setOption(ClockTypeOption.get("pseudo")); ksession = kbase.newStatefulKnowledgeSession(conf,null); clock = ksession.getSessionClock(); entryPoint = ksession.getWorkingMemoryEntryPoint("testEntryPoint"); assertThat(entryPoint).isNotNull(); }
