All,
Are DSL and DSLR files supported by the KnowledgeAgent / Changeset code. Here's the details of my test case: I have a Changeset file I'm trying to load which looks like the following: <?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' > <add> <resource source="classpath:com/test/general/" type="DSL" /> <resource source="classpath:com/test/general/" type="DSLR" /> </add> </change-set> There's a single DSL and a single DSLR file in this folder. I'm loading the change set as follows: KnowledgeAgent ka = KnowledgeAgentFactory.newKnowledgeAgent(agentName); ka.applyChangeSet(ResourceFactory.newClassPathResource(agentName + "-changeset.xml", getClass())); When I run this code, the logger suggests the DSL and DSLR are being loaded and compiled: [2009:10:299 16:10:52:info] KnowledgAgent created, with configuration: monitorChangeSetEvents=true scanResources=true scanDirectories=true ++ Constructing and applying changeSet: dsl-test [2009:10:299 16:10:52:info] KnowledegAgent has started listening for ChangeSet notifications (null: 3, 68): cvc-elt.1: Cannot find the declaration of element 'change-set'.

If I initialize the knowledgebase like this: KnowledgeBuilder kbuilder = KnowledgeBuilderFactory .newKnowledgeBuilder(); kbuilder.add(ResourceFactory .newClassPathResource("com/test/general/test.dsl"), ResourceType.DSL); kbuilder.add(ResourceFactory .newClassPathResource("com/test/general/test-dsl.dslr"), ResourceType.DSLR); if (kbuilder.hasErrors()) { throw new Exception(kbuilder.getErrors().toString()); } KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()); } ... and run the same output code I get a list of the rules that were loaded. Any clues why the different behavior? Macon
