By the way, the documentation at http://virtualschool.edu/wap doesn't
mention it but I built JSP so that I could implement web applications as
state machines whose states are Page instances instead of as files linked
by embedded html links as in JSP.
This is a *big* win. The most immediately obvious advantage is that pages
are full-fledged objects, so invalid links between them are reported at
compile time. See the "The Problem" link for further advantages.
