what captcha is spring roo using? I like the way it looks and would like to use it too. Is it easy to work with regular non-roo spring?

Roo does not provide a captcha service itself, although http://tanesha.net/projects/recaptcha4j/ provides a Java-based abstraction over the excellent reCAPTCHA service. I like reCAPTCHA for two reasons:

1. It helps digitize books, which is a practical and useful contribution to the collective knowledge of the world.

2. It reduces CPU time and bandwidth consumption on your own servers, as you need not create images. This will save you some money, depending on your system size. It also saves you the effort of managing/maintaining the service on your own machines; you only need a small library (such as linked above) to query it.

https://jira.springsource.org/browse/ROO-287 explains how to write third-party add-ons with the soon-to-be-released Roo 1.0.0.RC3. A reCAPTCHA service would be a superb example of a third-party add-on.

Yay, that's exactly what I needed Ben! Thank you so much!
