Will there be a JavaOne in 2010?

Yes, there will be a JavaOne Conference in 2010. JavaOne will be co-located with Oracle Develop during Oracle OpenWorld in San Francisco from September 19-23, 2010. You may experience and register for JavaOne as a standalone conference just as before, or you can attend Oracle Develop 2010 and/or Oracle OpenWorld as well; it's your choice. Furthermore, unlike in recent years, JavaOne will focus solely on Java Technology and its associated ecosystem. You're welcome to attend Oracle Develop and Oracle OpenWorld to gain insight into specific products. As usual, all Java users and partners are invited to submit papers and to attend JavaOne.

And here's more good news: We're taking JavaOne and Oracle Develop on the road, arriving in Brazil, Russia, India, and China in 2010/2011. For the first time, the rapidly growing developer communities in those countries will have access to the JavaOne experience. Although the currently scheduled Sun Tech Days in India and Russia will continue to occur as planned, JavaOne and Oracle Develop will occur in place of Sun Tech Days thereafter.
