Open-Source Java Communities

OpenJDK
As the heart of the Java platform, Java SE is the execution engine and core development technology that enables the Java technology's "write once, run anywhere" promise. By open sourcing the Java Development Kit (JDK), Sun's implementation of Java SE, Sun hopes to make the Java platform a new foundation of innovation and enhance its value as the ubiquitous, essential infrastructure of the Internet experience. Visit the community!

Mobile & Embedded
The Mobile & Embedded community site establishes a central location for the collaborative development of open source Java ME technologies and applications. Deployed in over 1.5 billion mobile and embedded devices, Java ME represents the ideal development platform for the creation and deployment of mobile data services. By open sourcing implementations of Java ME, Sun will enable the community to accelerate platform innovation, reduce development costs through the Java ME ecosystem, and, ultimately, drive a more consistent application platform. Visit the community!

GlassFish
The GlassFish open-source community collaborates on developing the Java EE Reference Implementation. The community delivers production-quality code, including a fully featured application server, TopLink Essentials, a Maven repository, and other components and tools that multiple companies and groups now use.
