Database-enabled RoR WAR on GlassFish

Filed under: web2.0 — arungupta @ 7:00 am

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

Follow up from here.

In this post I’ll show how a Ruby-on-Rails (RoR) application, talking to MySQL database, can be deployed as a WAR file on GlassFish V2. Here are the steps I followed:

  1. Create a HelloWorld RoR app talking to MySQL database as described here.
  2. Expand NetBeans project, expand ‘Configuration‘ and open ‘database.yml‘. Change production database entry from:

    production:
      adapter: mysql
      database: HelloWorld_production
      username: root
      password:
      host: localhost

    to

    production:
      adapter: jdbc
      driver: com.mysql.jdbc.Driver
      url: jdbc:mysql://localhost:3306/helloworld_development
      username: root
      password:

    Notice, even though this is production setting we are using a "development" database.

  3. In ‘Configuration‘, ‘environment.rb‘, add

    require 'jdbc_adapter'

    right before

    Rails::Initializer.run do |config|

    On some platforms, this syntax has caused problems. In that case, it may alternatively be specified (step 9) as: 

    if RUBY_PLATFORM =~ /java/
require 'rubygems'
RAILS_CONNECTION_ADAPTERS = %w(jdbc)
end
  4. Recreate the WAR file by invoking the command ‘rake war:standalone:create‘ from your application directory.
  5. Drop this WAR file in "domains/domain1/autodeploy" directory of your GlassFish instance and you are done!

With this, you’ve deployed a Ruby-on-Rails application accessing MySQL database as a WAR file on GlassFish V2.
