This is the biggest headache with Axis2. Typically the only time you have to worry about the ClassLoader is when your classes need access to resources. If your jars do this and don't provide methods for passing a ClassLoader or don't provide a way to pass the resource, then you are forced to put that jar in the WEB-INF/lib directory.
