Yes, I should have written "inclusive".

Jay M is working on the server, which is where the changes happened
that make servlets not work quite right.

Interesting idea. You would have to run the web server though.
And we would have to create something like "export servlet to
server" functionality for the eventual deployment on-line.

That's exactly what servlet.ss and servlet2.ss accomplish.
And that's what I had in mind for my freshmen course.

Your idea makes sense and is superior to my own one-time
use with freshmen. They didn't get too interested in web
programming then.

A warning though: it won't look as nice as an AJAX game :-)
