title: Recommendations for java captcha libraries
body: <p>I'm looking for a replacement for JCaptcha, which doesn't seem to be maintained any more, and isn't very good to begin with. The replacement has to integrate nicely with JavaEE webapps.</p>
  
  <p>As I can see it, there are three options:</p>
  
  <ul>
  <li>JCaptcha - No longer maintained, crude API</li>
  <li>SimpleCaptcha - much nicer API, nicer captchas, but seems to be Java6 only</li>
  <li>ReCaptcha - easy to use, uses remote web-service to generate captchas, but not much control over look and feel</li>
  </ul>
  
  <p>Has anyone used any others, that they'd recommend?</p>
