Best of Both Worlds: Java, Spring and Ruby Using JRuby

I've started putting together some resources related to JRuby and the Spring framework. There is a lot of interest in being able to write a Rails application and deploy it to an existing Java platform. I've been fortunate enough to land a job where I can spend a bit more time dedicated to mixing up Ruby and Java projects with the goal of speeding up development while still leveraging existing Java skills and platforms.
