jCaptcha is a really nice and simple library for supplying catcha image security to your java web application. Using it with Stripes makes it even simpler. Take a look at the 5 minute guide on their website. The main different between their implementation and mine is that I stream the image back from an ActionBean rather than a Servlet, which means I don't have to configure anything in the web.xml. Awesomeness.
