here are some observations..
it looks as though you are trying to get your values from the session when
you should be getting them from the form. in your doPost method you should
use request.getParameter(String paramName) to get the form element values.
you also do not have an ACTION attribute in your form tag. shouldn't you
include that to tell your page where to send the form?
