[rules-users] rules doesn't run after redeploying my application EAR in Jboss

Hello, I am running JBoss 5.1.0 GA with drools 5.1.1 (added run-time libraries). I have several DRL files which resides outside my EAR in a 'rules' directory. When the EAR loads, I am loading the DRLs using: *KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();* *for(...) {* * kbuilder.add(ResourceFactory.newFileResource(file), ResourceType.DRL); * } That works fine. When I do redeploy of the EAR, this code passed successfully, but the rules won't run anymore. When I switch to drools 5.0.1 run-time libraries, it returns to work. I need to work with 5.1.1 since I use some of the new features. I found an old post that was answered by Mark Proctor suggesting to use a single drools-all.jar: http://markmail.org/message/6yzc7c6ejdn6iekc#query:drools%20classloader%2... unfortunately, I could find such file in the 5.1.1 release. Other ideas that was tested and failed: 1. Tell Tomcat not to lock resources (configuration properties in context.xml) 2. Put all drools 5.1.1 jars and dependencies in the lib Any suggestion how to solve this issue? Thanks, Amit
