JavaOne is an annual gathering that began in 1996, established by Sun Microsystems to focus on Java technology developments, primarily aimed at Java developers. Traditionally, it took place in San Francisco, California, spanning Monday through Thursday during the summer or early autumn months. The conference featured a variety of technical presentations alongside Birds of a Feather (BOF) sessions covering diverse Java-related topics.
The event consistently drew large crowds; for instance, the 1999 conference attracted approximately 20,000 attendees at the Moscone Center. For many years, it was led by Sun executive and prominent Java advocate John Gage.
In 1999, the conference launched a Hackathon challenge conceived by Gage, where participants created Java applications for the Palm V device, utilizing its infrared port for communication and online registration.
After Oracle Corporation acquired Sun Microsystems in 2010, JavaOne was held concurrently with Oracle OpenWorld but shifted from the Moscone Center to nearby hotels on Mason Street. Some editions included an expanded setup with a tent covering part of the street area.
Oracle discontinued JavaOne in April 2018, replacing it with Oracle Code One, a more inclusive programming conference that ran for two years.
In March 2022, Oracle announced the revival of JavaOne scheduled for October 2022 as part of Oracle CloudWorld in Las Vegas, effectively succeeding the discontinued CodeOne event.
Oracle confirmed in March 2024 that JavaOne would return in March 2025 at Oracle Headquarters in Redwood Shores, California, close to its original San Francisco venue. This edition will celebrate Java’s 30th anniversary alongside the launch of Java 24.
