Trying to catch up a bit on Ruby/Rails/JRuby related news...

Two new NetBeans 6.1 Ruby tutorials: Getting Started With Ruby and Rails and Using Java Libraries in Rails Applications. The last topic is one of the big benefits of JRuby, one example is this report of Calling into Sun's SSO and another is this Tutorial showing Invoking Java 2D Graphics.

A recent adoption story is CSI's use of JRuby in a project on Infectious disease reporting and management. Slightly older is Nick's This Blog now Powered by GlassFish and JRuby.

Overall, very nice progress on the JRuby/Rails front. I believe the last set of formal releases were: Release of GlassFish Gem 0.3.0/0.3.1 (announcement and update), and JRuby Module in the Update Centers with JRuby 1.1.1. The interest continues to grow and it is moving closer to actual deployments; perhaps time to start a commercial support offering?

PS. Arun has a whole collection of applicable entries tagged JRuby.
