Re: [rules-users] Rules don't execute using MVEL syntax in RHS - Possible Bug

You are using a class called KnowledgeBuilder. With Drools 6, it is KieBuilder. Here is some simple code, good for testing (as I used it), although more sophisticated build procedures are recommended using maven and what not. - Both DRL versions (getAbxDef and abcDef) appear to work with 6.0.0 Final. KieServices kieServices = KieServices.Factory.get(); KieFileSystem kfs = kieServices.newKieFileSystem(); FileInputStream fis = new FileInputStream( "lostrule/lostrule.drl" ); kfs.write( "src/main/resources/lostrule.drl", kieServices.getResources().newInputStreamResource( fis ) ); KieBuilder kieBuilder = kieServices.newKieBuilder( kfs ).buildAll(); Results results = kieBuilder.getResults(); if( results.hasMessages( Message.Level.ERROR ) ){ System.out.println( results.getMessages() ); throw new IllegalStateException( "### errors ###" ); } KieContainer kieContainer = kieServices.newKieContainer( kieServices.getRepository().getDefaultReleaseId() ); KieBaseConfiguration config = kieServices.newKieBaseConfiguration(); config.setOption(EventProcessingOption.STREAM); KieBase kieBase = kieContainer.newKieBase( config ); kieSession = kieContainer.newKieSession(); On 09/05/2014, jlprat <jlprat(a)gmail.com&gt; wrote:
