[rules-users] loading rules and drools classes via URLClassLoader

Hi there, we tried to use drools jars from an url: 1. define an URLClassLoader with all the urls of the necessary drools jars in the search path. 2. initialize a KnowledgeBaseConfiguration with that class loader KnowledgeBaseConfiguration knowledgeBaseCfg = KnowledgeBaseFactory .newKnowledgeBaseConfiguration(null, dcURLClassLoader); 3. initialize a KnowledgeBase with that configuration KnowledgeBase kbase = KnowledgeBaseFactory .newKnowledgeBase(knowledgeBaseCfg); 4. initialize a KnowledgeBuilderConfiguration with that class loader KnowledgeBuilderConfiguration knowledgeBuilderCfg = KnowledgeBuilderFactory .newKnowledgeBuilderConfiguration(null, dcURLClassLoader); 5. initalize a knowledge builder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(kbase, knowledgeBuilderCfg); 6. adding a knowledge resource to that builder results in a org.drools.RuntimeDroolsException "Unable to load dialect org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java" if the drools jars are not in the start class path. Did we something wrong or uses drools while adding ressources a classloader different from that given in the configuration?.
