I was looking to do the same thing but didn't even realize that the CaptchaResponse annotation existed. My guess is that you need to create a getter method (with above annotation) on the Seam Component that handles the form you are associating the captcha input with. Because I was unaware of the annotation, I found another solution. If you are using the <s:validate/>/<s:decorate> in combination with the <h:inputText/> for the captcha input, you can use a custom message from your own message bundle: | <s:decorate id="captchaDecor"> | <h:inputText value="#{captcah.response}" required="true"> | <s:validate/> | </h:inputText> | <s:span rendered="#{invalid}"> | <h:outputText value="#{messages.invalidCaptcha}"/> | </s:span> | </s:decorate> | Note that "invalidCaptcha" should be whatever you named your property in your message bundle.
