If it's in the package com.abc.xyz, so you have to use: ResourceFactory.newClassPathResource("/com/abc/xyz/keyRykes.drl") Or ResourceFactory.newClassPathResource("com/abc/xyz/keyRykes.drl") I don't remember, it's one of those :p -----Message d'origine----- De : rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] De la part de bcarlson Envoyé : vendredi 28 mai 2010 06:13 À : rules-users(a)lists.jboss.org Objet : [rules-users] FileNotFoundException for drl file in classpath Hello, I'm relatively new to drools, and although I've gotten my first app working from the command line, I am not incorporating it into a web app, and having a heck of a time getting the drl file found! Long story short, the drl file is in the package: com.abc.xyz I'm trying to load it with the following: kbuilder.add(ResourceFactory.newClassPathResource("keyRules.drl",this.getClass()),ResourceType.DRL); and I've placed it in about 42 places throughout my app in the futile attempt to get it to load. What am I missing? Can someone help me understand the whole classpath loading? I mean, I've put the path to the .drl file in my classpath, and it's simply not finding the file.
