This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
To add to Paul's answer for the benefit of other readers. If you want to discuss a particular Java API and you can't see a forum for it, a posting in Other Java APIs is usually a good way to start. If it turns out that the discussion is actually more appropriate to another forum, or if it starts enough discussion that we think a new forum would be a good idea, your post will be moved, but don't let that upset you, it's just how Other Java APIs works.
