I'm looking for an API that generates image with a random number to display it in a form to check that a real user is filling this form (not a flooder)
Does any body knows about such an API (may be a custom tag ) ?

Thank You !

These are called Captchas. There's a link in that article to a project called JCaptcha that may be of some help.

Please do not cross-post the same question in multiple forums. It wastes people's time when multiple redundant conversations take place. Please continue any discussion of this topic in the Servlets forum.
