Welcome to Wikipedia's Java portal. Java refers to a number of computer software products and specifications from Sun Microsystems that together provide a system for developing application software and deploying it in a cross-platform environment. Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers. Java is nearly ubiquitous in mobile phones, Web servers and enterprise applications, and while less common on desktop computers, Java applets are often used to provide improved functionality while browsing the World Wide Web. Code is produced through writing in the Java programming language, then executed by a Java Virtual Machine (JVM). In 2006, Sun Microsystems made the bulk of its implementation of Java available under a public license.

JavaOne

Attendees at the 2004 JavaOne conference described their vision of the future of Java on a whiteboard.

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.[1]

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.

During the 2008 conference, 70 Moscone Center staff members and three attendees were sickened by an outbreak of norovirus.[2]

CommunityOne

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.

Tracks included:

  • Cloud Platforms – Development and deployment in the cloud
  • Social and Collaborative Platforms – Social networks and Web 2.0 trends
  • RIAs and Scripting – Rich Internet Applications, scripting and tools
  • Web Platforms – Dynamic languages, databases, and Web servers
  • Server-side Platforms – SOA, tools, application servers, and databases
  • Mobile Development – Mobile platforms, devices, tools and application development
  • Operating Systems and Infrastructure – Performance, virtualization, and native development
  • Free and Open – Open-source projects, business models, and trends

CommunityOne was discontinued after the acquisition of Sun by Oracle.
