Subclassing ActionServlet, and then overriding processValidate() to do
what you are describing above, certainly seems like a viable
approach. This is the primary reason that the processing logic in
ActionServlet has been divided into so many protected methods - so that
you can easily specialize the parts you want, without having to recode the
entire processing flow.
