This is what I assumed the problem is... I have spent a lot of time debugging Tomcat classloader issue (though certainly not as much as other people here). My document on Tomcat classloading that I am referencing: http://jakarta.apache.org/tomcat/tomcat-4.0-doc/class-loader-howto.html ... but it looks like things have changed below... > > Could you give me more insight here? > > I have no idea at this point.

Yes... this is my experience exactly. > Also, if JAXP is in the system classloader, you can never override it. Ug... "As mentioned above, the web application class loader diverges from the default Java 2 delegation model (in accordance with the recommendations in the Servlet Specification, version 2.3, section 9.6). When a request to load a class from the web application's WebappX class loader is processed, this class loader will look in the local repositories first, instead of delegating before looking. All other class loaders in Tomcat 4 follow the usual delegation pattern." Does this mean that Tomcat is now NOT in complaince with the Servlet 2.3 spec??? > Which JDK are you using ?
