I recommend switching the parameters around in your JspWrapperException to
match the Servlet 2.3's constructor order (message, exception, rather than
exception, message) and that will make the switch later much easier (just
change the classname, and not have to fiddle with re-ordering parameters).
You rock, Rick!
