The slides from this years JavaPolis is available here. Should have been there. Some interesting ideas, and nice to see on them. Check out the EJB 3.0 slides by Linda DeMichiel and the Hibernate 3 slides by Gavin King. King launches the idea of unifying the many context in an J2EE application (request, session, transaction etc). Would have been interesting hearing the talk.
Found this tip today and tested it out. Wow. If you got some bandwidth it should make page loading a lot faster. I’m not sure how it affects the servers, but we won’t notice yet will we. 😉
