What is GlassFish v3 Technology Preview 2 (TP2)?

GlassFish v3 Technology Preview 2 (TP2) is a milestone release of the
GlassFish v3 Application
Server currently under development.

The TP2 release gives you an early look at GlassFish v3 and its modular, lightweight, extensible
architecture. TP2 is not a full, feature-complete application server and is not suitable for production deployments. It
is suitable for experimentation and exploration, however, which is exactly what we hope you'll do. Experiment with the code,
take a look at the new approach being taken in GlassFish v3, and then [let us know] what you think
(maybe even get involved?).

See What's in GlassFish v3 TP2? for more information about what the release contains. See How do I get GlassFish v3 TP2 and get started? for download information and other helpful resources.
