Hello friends,
Has any one used Captcha image. These images are generally used for authentication.

I am using SimpleCaptcha which by default gives me image containing 5 characters. I have taken one session variable which is used to store these characters. But the session variable contain 6 character.

So while authenticating it always give me invalid match.

If any one has idea about it, please let me know.

Vijendra, please do not post the same question to multiple forums. It is confusing and wasteful of peoples time if multiple redundant conversations take place.

Since the question has little to do with JSPs, let's continue the discussion in the other thread.
