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 inaugurated in 1996 by Sun Microsystems to discuss Java technologies, primarily among Java developers. JavaOne is held in San Francisco, California typically running from Monday to Thursday. Technical sessions on a variety of topics are held during the day. In the evening, Birds of a Feather (BOF) sessions are held. BOF sessions 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 usually costs between $1795 to $1995 USD.

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, 67 Moscone Center staff members and three attendees were sickened by an outbreak of norovirus.[1]

After the 2010 acquisition of Sun by Oracle Corporation, the conference has been held concurrently with Oracle OpenWorld. Rather than being located in Moscone Center, the conference is now hosted at 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.

Each year at the conference there is a hardware device highlighted, typically made available to attendees before it is sold to the general public, or at a steep discount.

CommunityOne

<templatestyles src="Module:Hatnote/styles.css"></templatestyles>

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.

"Why the future doesn't need us"

William Nelson Joy (born November 8, 1954), commonly known as Bill Joy, is an American computer scientist. Joy co-founded Sun Microsystems in 1982 along with Vinod Khosla, Scott McNealy, Andy Bechtolsheim and Vaughan Pratt, and served as chief scientist at the company until 2003. He is widely known for having written the essay "Why the future doesn't need us", where he expresses deep concerns over the development of modern technologies. He has two children, Hayden and Maddie.

Sun

According to a Salon.com article, during the early 1980s DARPA had contracted the company Bolt, Beranek and Newman (BBN) to add TCP/IP to Berkeley UNIX. Joy had been instructed to plug BBN's stack into Berkeley Unix, but he refused to do so, as he had a low opinion of BBN's TCP/IP. So, Joy wrote his own high-performance TCP/IP stack. According to John Gage,

"BBN had a big contract to implement TCP/IP, but their stuff didn't work, and Joy's grad student stuff worked. So they had this big meeting and this grad student in a T-shirt shows up, and they said, 'How did you do this?' And Bill said, 'It's very simple — you read the protocol and write the code.'"

Rob Gurwitz, who was working at BBN at the time, disputes this version of events.

In 1986, Joy was awarded a Grace Murray Hopper Award by the ACM for his work on the Berkeley UNIX Operating System.

Joy was also a primary figure in the development of the SPARC microprocessors, the Java programming language, Jini / JavaSpaces and JXTA.

On September 9, 2003 Sun announced that Bill Joy was leaving the company and that he "is taking time to consider his next move and has no definite plans".
