My friend Rodrigo just told me that he has an article on java.sun.com about the RSS Utility JSP tag library he wrote for Sun during his last contract there.
It is a fairly short article, but it is a pretty well formed utility that I would imagine could be useful to a number of organizations. It basically lets you format and display RSS derived data in any JSP page. This taglib should save you the step of parsing RSS (XML) and displaying its contents.
Way to go Rodrigo!
