My guess? ClassNotFoundException is rooted in some other exception. Such
as a different error is thrown during class initiation. Such as a static {
doStuff();} block where doStuff does bad stuff.
Hopefully there is more stack trace out there. If the JSP has static
initializers - wrap them in try {} catch blocks{} even if you think they
don't need wrapped in those blocks.
