15.9.2. Adding a CAPTCHA to a form

It is easy to add a CAPTCHA challenge to a form:

<h:graphicImage value="/seam/resource/captcha"/>
  <h:inputText id="verifyCaptcha" value="#{captcha.response}" 
     required="true">
    <s:validate />
  </h:inputText>
<h:message for="verifyCaptcha"/>

<h:graphicImage value="/seam/resource/captcha"/>
  <h:inputText id="verifyCaptcha" value="#{captcha.response}" 
     required="true">
    <s:validate />
  </h:inputText>
<h:message for="verifyCaptcha"/>

Copy to Clipboard

Toggle word wrap

That is all you need to do. The graphicImage control displays the CAPTCHA challenge, and the inputText receives the user's response. The response is automatically validated against the CAPTCHA when the form is submitted.
