JavaOne is an annual conference organized by Oracle Corporation to discuss Java technologies, primarily among Java developers. JavaOne is held in San Francisco, California typically running from a Monday to Thursday in September or October. Technical sessions on a variety of topics are held during the day. In the evening, Birds of a Feather (BOF) sessions are held, which allow people to focus on a particular aspect of Java technology.
Access to the technical sessions, keynote presentations, exhibits and BOF sessions requires a conference pass, which costs US$2,050.
The conference was first organized in 1996 by Sun Microsystems, which was purchased in 2010 by Oracle Corporation. After the acquisition, the conference has been held concurrently with Oracle OpenWorld. The conference was moved from Moscone Center to hotels on nearby Mason Street. In some years, one block of Mason was closed and covered with a tent, which formed part of the conference venue.
In 1999, the conference played host to an event called the Hackathon, a challenge set by John Gage. Attendees were to write a program in Java for the new Palm V using the infrared port to communicate with other Palm users and register the device on the Internet.
Each conference highlights a hardware device, typically made available to attendees before it is sold to the general public, or at a steep discount:
- 1998: Java ring
- 1999: Palm V
- 2002: Sharp Zaurus
- 2004: Homepod, a wireless MP3 device from Gloolabs
- 2006: SavaJe Jasper S20 phone
- 2007: RS Media programmable robot
- 2008: Sentilla Perk Kit, Pulse Smartpen, Sony Ericsson K850i
- 2009: HTC Diamond with JavaFX pre-installed
From 2007 to 2009, an associated one-day event, CommunityOne, was held, for the broader free and open-source developer community.
In 2009, CommunityOne expanded to New York City (CommunityOne East, March 18–19) and to Oslo, Norway (CommunityOne North, April 15). The third annual CommunityOne in San Francisco took place from June 1–3, 2009, at Moscone Center.
