Sun is now making all their technical sessions from Java One available online. You can get the PDF for any of them and they are gradually getting the full audio plus slides up (e.g. all the 2006 presentations and about 20-25% of the 2007 presentations are up in full audio/slides form now, the remainder of the 2007 stuff is PDF only for the moment). You have to join the Sun Developer Network (SDN) but signup for that is free.
The presentations are pretty awesome. I’m watching the one on the Java Persistence API from 2006 and there are several others I have my eye on for later. This is an excellent educational resource and if you develop in Java for a living you would be remiss not to go through what’s available there.
