GlassFish:
The GlassFish Community implements open-source Java EE 5 application servers. GlassFish is a robust business-compatible application server that delivers product-level quality and is free for development, deployment, and redistribution.
GlassFish is the name of an Open Source Development Project used to build a Java EE 5 Application Server. It is based on the source code of Sun Java System Application Server PE 9 provided by Sun Microsystems and the TopLink persistent code contributed by Oracle. This project provides a structured process for developing high-quality application servers, providing new functions at an unprecedented speed. This is a response to Java developers who want to obtain the source code and contribute to the development of Sun's next-generation Application Server Based on GlassFish. This project aims to promote communication between Sun and Oracle engineers and the Community. It will allow all developers to participate in the development process of the application server.
