Linux & open source is core to Sun

GlassFish

GlassFish is a free, open source application server that implements the newest Java EE 5 (the next version of the J2EE platform) platform features. Designed to encourage communication between Sun engineers and the community, this project enables all developers to participate in Sun's application server development process.

Grid Engine

Sponsored by Sun and hosted by CollabNet, the Grid Engine project provides distributed resource management software to satisfy compute farm to grid computing requirements. Advances Grid Engine technology, establishes community-driven distributed computing standards, and enables developers to create innovative services and applications across distributed, heterogeneous compute environments.

java.net

Formed by a diverse group of Sun engineers, researchers, technologists, and evangelists to provide a common site for Java technology conversations and development projects. The community continues to attract industry associations, software vendors, universities, and individual developers and hobbyists. Meeting, sharing ideas, and using java.net collaboration tools, these new communities uncover synergies and create new solutions that expand the value of Java technology.

Jini Network Technology

Created by Sun and advanced by an active community, the Jini technology enables Java dynamic networking for creating highly adaptive systems. Empowered by the release of Sun's Jini network technology contributions under an open source license, the Jini community expands the use of this significant enterprise technology.

OpenSolaris Operating System

An open source distribution of the OpenSolaris code base provided by the world's best release engineering and software testing organization - based on the trusted foundation of some of the most complex IT infrastructures on the planet. This open source version of the Solaris OS is a community development effort. OpenSolaris.org offers a forum for developers and users to converse and develop collaboratively to enhance the OS. Developers can freely use any of the OpenSolaris code for without fear of IP patent or copyright infringement on Sun.

JXTA Technology

An open protocols set that allows any network connected device—from cell phones and wireless PDAs to PCs and servers—to communicate and collaborate in a peer-to-peer (P2P) manner. The diverse JXTA community includes ISVs, corporate IT, and academia members, as well as many independent developers and consultants. jxta.org members interact online, through e-mail list discussions, project collaboration, and more, as well as in live community meetings.

NetBeans Project

Founded by Sun in 2000 and hosted by CollabNet on Sun's dime, NetBeans.org is a democratic, independent community with thousands of subscribers and several full commercial offerings built on the reference implementation. Two base products—the NetBeans IDE and NetBeans platform—address the needs of developers, users and businesses which rely on NetBeans as a basis for products.

OpenOffice.org

An open source software release that makes the OpenDocument format a viable alternative for millions of people worldwide. Originating in Europe, OpenOffice.org software offers a multiplatform office productivity suite. While Sun is the main sponsor and primary contributor, OpenOffice.org is developed, supported, and promoted by an international community of volunteers.

SunSource.net

An information site devoted to Sun's free and open source project involvement. Offers the latest updates on the free and open source projects in which Sun is involved, as well as late-breaking news on general open source topics.

Open Single Sign-On

Built on the code base of Sun Java(tm) System Access Manager product, a core identity infrastructure product offered by Sun. Open SSO provides the first open source offering of core identity services to facilitate the implementation of transparent Single Sign-On for securing web infrastructures.

Open ESB

The first fully open source Enterprise Service Bus implementation based on the Java Business Integration (JBI) specification (JSR 208) and reference implementation

OpenSPARC

The OpenSPARC project is making the hardware source code of the recently announced UltraSPARC T1 processor available under an Open Source license. This technology offers a wide range of innovative opportunities. The project lowers entry costs through access to existing hardware designs, allowing more developers to engage, and increasing opportunity to pursue specialized implementations.
