All you need to do is add the jcaptcha jar to your project, make a reference to the SimpleImageCaptchaServlet in your web.xml and then use the servlet session id to validate what the user submits on your form against the captcha service.

...

String userCaptchaResponse = request.getParameter("jcaptcha");
boolean captchaPassed = SimpleImageCaptchaServlet.validateResponse(request, userCaptchaResponse);
if(captchaPassed){
// proceed to submit action
}else{
// return error to user
}

And that's it!
