A couple of problems here:

You're calling System.out.println, which is just sending output to standard out - not to the browser. Try changing "System.out.println" to just "out.println"

It looks like you've defined doPost() in your servlet code, but your javascript is using the "GET" method. Rename doPost() to doGet(), or define both of them.

That being said, you probably shouldn't bother with the javascript at all until you've actually got the servlet working, to keep it simple. You should be able to test it by loading /ProcessForm?email=testing in your browser and see some output. Once you get that going, then you can start worrying about the front-end code.

Hope this helps get you started.
