SAN FRANCISCO -- JavaOne(SM) Developer Conference -- June 27, 2005 -- Sun Microsystems, Inc. (NASDAQ: SUNW), founder and leading advocate for Java(TM) technology, marked the 10th birthday of Java technology's debut with major new alliances and developer programs aimed at building on Java technology's pervasiveness in popular technology products worldwide. Sun also is using the JavaOne conference as a launch pad for revealing how it will accelerate Java technology's adoption and fuel economic growth over the next 10 years through a number of significant product and technology announcements, including plans to release key Java products to the open source community.

Jonathan Schwartz, president and chief operating officer at Sun Microsystems, opened the event with a keynote address that stressed the importance of participation in stimulating market growth, building communities and driving social progress in a world that is increasingly network-centric.

"Opening technologies and building communities lowers barriers for adoption and results in more opportunity for participation and growth. This has led to a multi-billion-dollar Java industry with more than 4.5 million Java technology developers who are creating new services for over 2.5 billion Java platform-enabled devices worldwide," said Jonathan Schwartz. "Open sourcing key technologies like the Solaris Operating System and enterprise Java products will help Sun provide individuals, businesses and governments with the new tools, increased security and breakthrough technologies that lead to economic expansion and social progress in the next age of network computing - the Participation Age."

Java Technology Drives Billions of Smart Devices Around the World

During the opening keynote, Schwartz pointed to the rapid growth and acceptance of Java technology in a number of industries, markets and communities. Examples of this include:

• 1 billion Java technology-enabled smart cards
• 708 million Java technology-enabled handsets (1)
• 700 million Java technology-enabled PCs
• More than 140 Java platform carrier deployments
• 912 Java Community Process(SM) [JCP(SM)] members

Schwartz also pointed to support from both the Java community and global technology partners, like IBM and others, as a strong indicator of Java technology's continued importance in driving innovation and social progress.
