Is it possible to avoid submitting empty forms with JSTL?

Question

I have a form with a bunch of radio buttons, and a submit button. When a radio button is selected, I'm passing a query string to the servlet for further processing. But when none is selected and the Submit button is pressed, I get an exception, obviously. Is there anyway to avoid this? As in, avoid submitting empty forms using JSTL?

Don't submit the form unless a selection has been made. – Mathemats Jan 14 '16 at 01:09 — Mathemats, Jan 14 '16 at 01:09

You can disable the submit button until a selection is made. Try using JavaScript or Jquery

see JQuery Onselect?
