In his presentation Beyond Blogging: Feeds in Action, Dave Johnson, Staff Engineer/SW Sun Microsystems explains the feed formats RSS and Atom, and demonstrates how to use ROME to consume and produce feeds.
When I build autodiscovered RSS feeds for my project, I had trouble getting started with ROME and producing feeds. Then I found Dave's slideshare presentation. The presentation originally given at the 2007 JavaOneSM Conference contains some very helpful code samples.
For reference: Project ROME is hosted at java.net.
