I don't think you are using jQuery.ajax correctly. The url should be the url
to which the submitted form data should be sent. Also, the jQuery.ajax call
does not appear to actually send any data (it takes a 'data' argument). See
http://code.google.com/p/web2py/source/browse/applications/welcome/static/js/web2py_ajax.js#54
for
how web2py handles Ajax form submission.
