Here's what you could do:
Use a jsp for your initial form. When the user submits the form, if the input is
invalid, set a session var to indicate the particular error condition, and then
redirect (using Response.sendRedirect()) to the form.jsp itself. Now use the
value of the session vars set in the servlet and javascript alerts to inform the
user of what was wrong.
