[jboss-jira] [JBoss JIRA] (JBRULES-3630) ClassPathResources within ChangeSet are loaded using wrong ClassLoader

ClassPathResources within ChangeSet are loaded using wrong ClassLoader ---------------------------------------------------------------------- Key: JBRULES-3630 URL: https://issues.jboss.org/browse/JBRULES-3630 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core Affects Versions: 5.1.1.FINAL, 5.4.0.Final Environment: Win7 / Java6 / JBoss6 Reporter: Chris Rankin Assignee: Mario Fusco Fix For: 5.4.1.Final, 5.5.0.Beta1 Attachments: ResourceHandler.diff I am trying to load a "rules" JAR dynamically. This JAR contains a {{change-set.xml}} and all of its DRL files: {code:XML} <?xml version="1.0" encoding="UTF-8"?> <change-set xmlns='http://drools.org/drools-5.0/change-set' xmlns:xs='http://www.w3.org/2001/XMLSchema-instance' xs:schemaLocation='http://drools.org/drools-5.0/change-set http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/... <add> <resource source='classpath:com/my/stuff/rules/Stuff.drl' type='DRL' /> </add> </change-set> {code} I am loading the JAR dynamically via {{URLClassLoader}} and _successfully_ creating the ChangeSet resource: {code} Resource changeSet = ResourceFactory.newClassPathResource("change-set.xml", classLoader);{code} However, it then always explodes when I try to add the resource to the {{KnowledgeBuilder}}, complaining that "'com/my/stuff/rules/Stuff.drl' cannot be opened because it does not exist". I am suspecting that the {{KnowledgeBuilder}} is not using my class loader to load {{Stuff.drl}}, despite me passing the correct class loader in via {{KnowledgeBuilderConfiguration}}. (And the "changeset:" handling in {{org.drools.xml.changeset.ResourceHandler}} would seem to support my theory.)
