Java technology was created as a computer programming tool in a small, secret effort called "the Green Project" at Sun Microsystems in 1991.

The secret "Green Team," fully staffed at 13 people and led by James Gosling, locked themselves away in an anonymous office on Sand Hill Road in Menlo Park, cut off all regular communications with Sun, and worked around the clock for 18 months.

They were trying to anticipate and plan for the "next wave" in computing. Their initial conclusion was that at least one significant trend would be the convergence of digitally controlled consumer devices and computers.

A device-independent programming language code-named "Oak" was the result.

To demonstrate how this new language could power the future of digital devices, the Green Team developed an interactive, handheld home-entertainment device controller targeted at the digital cable television industry. But the idea was too far ahead of its time, and the digital cable television industry wasn't ready for the leap forward that Java technology offered them.

As it turns out, the Internet was ready for Java technology, and just in time for its initial public introduction in 1995, the team was able to announce that the Netscape Navigator Internet browser would incorporate Java technology.

Now, nearing its tenth year, the Java platform has attracted over 4 million software developers, worldwide use in every major industry segment, and a presence in a wide range of devices, computers, and networks of any programming technology.

In fact, its versatility, efficiency, platform portability, and security have made it the ideal technology for network computing, so that today, Java powers more than 1.75 billion devices:
over 650 million PCs
579 million mobile phones and other handheld devices
750 million smart cards
plus set-top boxes, printers, web cams, games, car navigation systems, lottery terminals, medical devices, parking payment stations, etc.
Today, you can find Java technology in networks and devices that range from the Internet and scientific supercomputers to laptops and cell phones, from Wall Street market simulators to home game players and credit cards -- just about everywhere.

The best way to preview these applications is to explore, the ultimate marketplace, showcase, and central information resource for businesses, consumers, and software developers who use Java technology.

sun filed a lawsuit that ended like this


The agreements involve payments of $700 million to Sun by Microsoft to resolve pending antitrust issues and $900 million to resolve patent issues. In addition, Sun and Microsoft have agreed to pay royalties for use of each other's technology, with Microsoft making an up-front payment of $350 million and Sun making payments when this technology is incorporated into its server products.

The agreements signed today include the following elements:

Technical Collaboration: The Technical Collaboration Agreement will provide both companies with access to aspects of each other's server-based technology and will enable them to use this information to develop new server software products that will work better together. The cooperation will initially center on Windows Server and Windows Client, but will eventually include other important areas, including email and database software. For example, one of the important elements of large scale computing environments is software to manage user identities, authentication and authorization. As a result of this agreement, Sun and Microsoft engineers will cooperate to allow identity information to be easily shared between Microsoft Active Directory and the Sun Java System Identity Server, resulting in less complex and more secure computing environments.

Microsoft Communications Protocol Program: Sun has agreed to sign a license for the Windows desktop operating system communications protocols under Microsoft's Communications Protocol Program, established pursuant to Microsoft's consent decree and final judgment with the U.S. Department of Justice and 18 state attorneys general.
Microsoft Support for Java: The companies have agreed that Microsoft may continue to provide product support for the Microsoft Java Virtual Machine that customers have deployed in Microsoft's products.

Windows Certification for Sun Server: Sun and Microsoft today are announcing Windows certification for Sun's Xeon servers. In addition, the Windows certification process for Sun's Opteron-based servers is moving forward.

Future Collaboration for Java and .NET: Sun and Microsoft have agreed that they will work together to improve technical collaboration between their Java and .NET technologies.

Patents and Intellectual Property: The parties have agreed to a broad covenant not to sue with respect to all past patent infringement claims they may have against each other. The agreement also provides for potential future extensions of this type of covenant. The two companies have also agreed to embark on negotiations for a patent cross-license agreement between them.

Legal Settlements: The two companies are settling and terminating their lawsuit in the United States. Sun is also satisfied that the agreements announced today satisfy the objectives it was pursuing in the EU actions pending against Microsoft.


msjvm faq -



A self-contained operating environment that behaves as if it is a separate computer. For example, Java applets run in a Java virtual machine (VM) that has no access to the host operating system.

This design has two advantages:

System Independence: A Java application will run the same in any Java VM, regardless of the hardware and software underlying the system.

Security: Because the VM has no contact with the operating system, there is little possibility of a Java program damaging other files or applications.

The second advantage, however, has a downside. Because programs running in a VM are separate from the operating system, they cannot take advantage of special operating system features.
