I noticed that not all the developers that use JDeveloper were able to come to this year's Oracle Open World in San Francisco. So if you are one of those who missed it, at least you can catch the slides from the seminars you missed.
Don't miss the link to more presentations, including those not done by Oracle employees, at the end of the page.
Not quite like being there and actually hearing the lectures and watching the demos - but better than nothing.
See you next year?
