Re: [rules-users] KnowledgeAgent custom class loader not working for PKG resources

I have a 5.4.0-SNAPSHOT version with your changes built and made the KnowledgeAgentConfiguration change you suggested. My test code is now like this:**** ** ** KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration();**** aconf.setProperty("drools.agent.useKBaseClassLoaderForCompiling", "true"); // new**** // KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("test", kbase, aconf, kbuilderConfig);**** KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("test", kbase, aconf); // not passing kBuilderConfig**** ** ** My project is attached – let me know if it doesn’t upload.**** ** ** I can see I’m stepping threw your new code, and I’m now getting a new error, below.**** ** ** I can also tell you that we tried to just use the KnowledgeBuilder with custom classloader as in the Expert documentation (4.1.1) and could not get that to work either.
