The GlassFish Project is a gathering place for developers who wish to participate in the community development of the latest version of the Javaâ„¢ 2, Enterprise Edition (J2EEâ„¢) SDK. Developers can participate in the development process where community members can review source code, submit improvements, and join in technical discussions. GlassFish is a renewed partnership between Sun and the larger enterprise Java community.
Community development means that you work under the Java Research License (JRL) with the important understanding of ensuring compatibility of J2EE. It is the response to our developers who want access to the source code, the ability to contribute to the development of GlassFish, the server which is first with specifications, and enable them to understand Sun's J2EE development process while maintaining compatibility of J2EE. We only ask that you accept the JRL before checking out the project details.
I'm happy to announce that GlassFish is available for all developers to checkout, learn from and contribute to. I've worked on Sun's J2EE SDK for the past 6 years in some form or another. The people I've worked with on GlassFish are very smart, responsive and nice to work with. A multitude of us have given various talks at JavaOne and other conferences. Now you have the ability to work with us more closely than ever before. And we have the ability to get to work more closely with the numerous J2EE developers, many of whom are working on great implementations/additions to the technologies. It's a great way for all of us to build even better technologies.
At this time you have access to all the J2EE 5.0 based server code. Currently the webtier module is online with web pages and mailing lists to help understand that module and provide a mechanism to learn about what is available. We are working on creating the pages for the other modules. The webtier module includes code for a new HTTP connector, Grizzly, written entirely in Java and uses Java's NIO technology. For an overview on how it works see the webtier page of GlassFish.
You can also download the weekly promoted builds, install the server and checkout Grizzly and other new features that way.
