Java University at JavaOne 2008:
I'd like to make some promotion for Java University.
If you want to know about the real stuff (the stuff you need in practice) presented by professional instructors (people that are passionate about learning and teaching technology), then Java University is the place to be!
Here are a few talks that I strongly recommend (if only because of the presenters (I know them personally))* How Java EE 5 and SOA Help in Architecting and Designing Robust Enterprise Applications, presented by Joe Boulenouar
Designing and Implementing Secure Java Technology Web Services, presented by John Ranta
Web 2.0: Leveraging the Project jMaki and Google Web Toolkits for Rapid Website Development, presented by Evan Troyka
Developing Portable Java EE Applications with the Enterprise JavaBeans 3.x Component API, presented by Bob Kellogg
But, I am sure that the other talks are worth attending as well.
