Part II of this article series is available here.
I love openid4java, but their sample application code is lacking. Lucky for guys like me, I guess, who write articles about stuff like that, huh?
This article comes with a complete, working sample application that you should be able to build and deploy to Tomcat 5.5.x right out of the box (I tested it with Tomcat 5.5.27).
I’d love to hear what you think of this article.
