If you didn't get the chance to go to JavaOne, all the sessions along with their accompanying slides are available online. Access to all the content costs $245. For that price you get all the presentations (about 2000) from Oracle OpenWorld, JavaOne, and Oracle Develop. For details, check out the On Demand Preview.
Alternatively you can find some JavaOne highlights videos on the Oracle Media Network. Just look under the "Newest" tab at the bottom.
