The code does not match the doc, nor observed behavior. The WebappClassLoader does have a delegate field that can be used to force a search via the parent and system classloaders before WEB-INF/lib and WEB-INF/classes, but the value of that field is normally false. It can be set by the delegate attribute of a <Loader> element nested inside a <Context> element, but it's unlikely you're doing that. When delegate is false (the default), the WEB-INF directories are searched before system or common. The WebappClassLoader also has a provision for forcing delegation for certain packages, but that package list is empty in the current implementation. It could be filled in by a subclass (but there are none in Tomcat). All of the above is based on 6.0.20. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
