JRuby 1.0.3 was recently released and so was Rails 2.0. I decided to try JRuby 1.0.3 + Rails 2.0 and realized that a few additional steps (because of Rails 2.0) are required to get a trivial Hello World applcation up and running. Here are the steps:

- Also include JAVA_HOME/bin and JRUBY_HOME/bin in PATH for convenience.
- Install Rails
2.0 as shown below:
