Below is the screenshot from a previously deployed Redmine application, now on the GlassFish gem:

Simple isn't it ?

If your Rails application does not work on the gem, file bugs here with "jruby" as "subcomponent" (default version is "v3").

Alternatively, you can download GlassFish v3 TP2 and deploy your applications to leverage complete Java EE functionality.

You can also configure JRuby 1.1.2 as a Ruby platform in NetBeans 6.1 as described in TOTD #27.
