You want to validate a captcha with a client side language? That captcha would be fairly worthless then.

Just submit form to server side the usual way and use Java to validate it. Read the documentation which come along the captcha API in question.

You haven't said what the problem is with the captcha yet. What Java code do you have so far in your servlet/JSP?

Security is to be validated at the server side, period.
Captcha is just a security technique. That you're using it the wrong way, doesn't make it a bad solution.

As said, just submit the form to the server, let the server validate the captcha and take action accordingly.
