JavaOne was an annual conference first organized in 1996 by Sun Microsystems to discuss Java technologies, primarily among Java developers. It was held in San Francisco, California, typically running from a Monday to Thursday in September or October. Technical sessions and Birds of a Feather (BOF) sessions on a variety of Java-related topics were held throughout the week.
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.
After the acquisition of Sun by Oracle Corporation in 2010, the conference was 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 April 2018, Oracle announced that the JavaOne conference would be discontinued, in favor of a more general programming conference called Oracle Code One.
Several of the conferences highlighted a hardware device, typically made available to attendees before it is sold to the general public, or at a steep discount:
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.
