Creating and Deploying a Simple Rails Application with Warbler

The procedure for creating a simple Rails application for Warbler, is similar to the procedure described in Creating a Simple Rails Application.

To Create a Rails Application

1. Create a new directory for the Warbler application. For example:

   mkdir rails-warbler

2. Change to rails-warbler directory and create a sample application called hello:

   jruby -S rails hello

3. 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.

4. 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 ]

5. Exit and save the file.

6. 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.

To Deploy the WAR File

1. Change to the rails-warbler/hello application directory.

2. Deploy the application WAR file to the GlassFish Server by running the asadmin command:

   asadmin deploy hello.war

3. Run the hello application by entering the following URL in your browser:

   http://host-name:port/hello
