Disclaimer: I have a Java background :) JRuby is great. If you're building an intranet application in Ruby you should definitely pick up JRuby and Glassfish to host it, that's a no-brainer. And I would also suggest to guys at Engine Yard, Heroku and others to take a closer look at this Ruby implementation. They could save a big buck on it, I suppose. The startup time is noticeable sometimes that's why I personally prefer developing with MRI, but I use JRuby for deployment and continuous integration.
