I recently did some investigation into the WebLogic Filtering ClassLoader, and the larger ClassLoader picture for WebLogic and put together a presentation on it. I also included a demo of the ClassLoader Analysis Tool (CAT) that is a very useful tool for looking under the covers of the WebLogic ClassLoader operation.
The CAT analyzes class conflicts and shows you the conflicting library/JAR in your application that is in conflict with the WebLogic-packaged libraries. You can see in the screenshot from the CAT below:
Not only does CAT analyze conflicts it also provides the XML needed to add to the WebLogic Deployment descriptors (weblogic.xml and weblogic-application.xml):
Check out the presentation and demo below:
