Agreed that it could be more clear, but I was looking at the javadoc, not
the spec. I finally found the info in Ed Burns book page 361.
One gotcha I found was that if you want to override createResource, then you
also must override handleResourceRequest, because the wrapper implementation
of handleResourceRequest delegates to the wrapped instance, which calls its
own createResource instead of the one you implemented in your extension of
ResourceHandlerWrapper.
Good luck,
Joel
