The procedure for creating a simple Rails application for Warbler, is similar to
the procedure described in 
Creating a Simple Rails Application.
Create a new directory for the Warbler application. For example:
mkdir rails-warbler
Change to rails-warbler directory and create a sample application called hello:
jruby -S rails hello
Edit the enviroment.rb file to indicate that your application does not use a database:
Open rails-warbler/hello/config/environment.rb in a text editor.
Remove the pound character (#) in front of line 21 to uncomment it so that it reads as follows and save:
config.frameworks -= [ :active_record, :active_resource, :action_mailer ]
Exit and save the file.
Use Warbler to create a war file in rails-warbler/hello application directory:
jruby -S warble
This creates a hello.war file in the directory.
Change to the rails-warbler/hello application directory.
Deploy the application WAR file to the Enterprise Server by running the asadmin command:
asadmin deploy hello.war
Run the hello application by entering the following URL in your browser:
http://<hostname>:<port>/hello
