The default ExceptionMappingInterceptor is "closer" to the error (as it is configured by default), so it will intercept it first (on the way out... [1]). If you already have configured exception mappings for that interceptor, it will never reach your interceptor. It might be better for you to replace the the interceptor in the stack, as you have already tried. You can set up your own default stack in your application struts.xml file. It's a bit of duplication, but there's no need to edit the framework supplied configuration files.
