To quote myself: anonymous wrote : Oops, the code I provided only displays a custom captcha image, it cannot perform the validation. You have to create a custom "captcha" component. The captcha classes provided by Seam are tightly related so you have to create a new copy of all of them if you want to have a custom create method. btw Maybe your idea could work too. I mean, overriding CaptchaImage and changing the precedence so that it comes created first. I don't think you should change the resource path though ("/mycaptcha"). I don't have Seam's source code at my disposal but I think that's what the error you are receiving is for.
