News.com had a quick report (well no real information there) that Canonical (the commercial interest behind Ubuntu) and Sun has partnered to include the Glassfish Java EE server in the Ubuntu Server product, I think this is a nice thing to do, and hopefully it will be up there competing with the RedHat/Jboss stack (Red Hat Application Stack).

At this time I think that glassfish is more bleeding edge than Jboss, and perhaps the only real “final” Java EE server ready for production (Although I argue that the JBoss AS is real stable and production-ready as-well).
