hello, i devloped a custom rule editor able to create drl file and save them in file system under a given directory. (e.g. c:\savedRules\rule.drl). The problem is that once the rule is saved i need to run it with drools engine. In my class i try to load rule in this way: KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add(ResourceFactory.newClassPathResource("c:\savedRules\rule.drl"), ResourceType.DRL); but its doesn't work. the exception is "rule.drl cannot be opened because it does not exist" but it actually exists.... What am I doing wrong? there is another way to load rules directly from file sistem? thanks in advice. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Drools-5-load-drl-rul...
