Hello,

I am trying to implement a simple captcha for my login form.

i.e after entering the user id/pwd the user should also enter the captcha and then go to next page.

First of all I need to know is there any captcha server required to implement it. Or if not, then how could this be implemented . ( any specific jars etc required).

Thanks
Sagar

jcaptcha seems to be popular.


Ping & DNS - updated with new look and Ping home screen widget
 
It is sorta covered in the JavaRanch Style Guide.
