GlassFish Project - v3 Preview

Note: GlassFish 3.0.1 Final has now been released, please consider using that version instead!

Welcome to GlassFish v3 Preview, a highly productive platform for building enterprise applications with dynamic languages and early access to Java EE 6 technologies. It is an early access, preview release of Java EE 6 technologies with community-only support.

What is GlassFish v3 Preview?

GlassFish v3 Preview offers early access to Java EE 6 technologies and the new Java Platform, Enterprise Edition 6 Web Profile SDK Preview. Developers building traditional enterprise applications have access to the rich features of the full Java EE 6 platform. Developers building web applications targeting the Web container can use the Java EE 6 Web Profile. Because GlassFish v3 uses a microkernel architecture based on OSGi, developers can begin with the Java EE 6 Web Profile and use the Update Center to dynamically upgrade to the full Java EE 6 platform!

GlassFish v3 Preview also features alignment with NetBeans 6.7 RC and Eclipse 3.4, scripting support including JRuby/Ruby, Grails and jMaki, an easy-to-use Admin Console and Update Center connectivity. After installing and using GlassFish v3 Preview, let us know what you think and, of course, feel free to get involved!
