Ruby-on-Rails Hello World on GlassFish

UPDATE: Simplified steps for GlassFish V2 are available here and for V3 here.

Ashish described how to create RoRaWAR (Ruby on Rails as Web ARchive). I decided to try these instructions on GlassFish V2 b46. Here are the steps I followed:

1. Create a simple "Hello World" RoR application using NetBeans 6.0 M9 following this screencast. NetBeans IDE creates a standard Rails application for you which can be easily created using "rails hello_demo" command as well.
2. Install the "goldspike" (nee rails-integration) plug-in by giving the following command:
   
   script/plugin install svn://rubyforge.org/var/svn/jruby-extras/trunk/rails-integration/plugins/goldspike
   
   On a Windows machine, this command can be invoked as:
   
   ruby script/plugin install svn://rubyforge.org/var/svn/jruby-extras/trunk/rails-integration/plugins/goldspike
   
   The correct installation of this plug-in can be confirmed by checking for the presence of "vendor/plugins/goldspike" directory in your application directory. This plug-in's purpose is to WAR'up a RoR application.
3. After the plug-in is installed, right-select the NetBeans project, select "Run Rake Target", select "Refresh Target List". This will add a new category, "war", of rake targets. Select "war", "standalone", "create" to create a stand-alone WAR file. This is equivalent to invoking the command "rake war:standalone:create". This will archive the Rails framework libraries in the WAR file.
4. Drop this WAR file in "domains/domain1/autodeploy" directory of your GlassFish instance and you are done!

This is really simple. I'll add database interaction in this app and report back.
