JRuby on Rails, GlassFish Server, and GlassFish v3 Gem

Developing and deploying Rails applications on Oracle GlassFish Server offers several advantages over using a typical web server for running Rails applications:

• Provides a simple, integrated deployment environment; develop and deploy from a single toolkit

• Enables deployment of multiple Rails applications to a single GlassFish Server instance

• Makes it possible to configure a single Rails application to handle multiple requests

Rails applications can be deployed on GlassFish Server in either of two ways:

• Deploy the application to a directory in the GlassFish Server domain.

• Run the application using GlassFish v3 Gem.

A Gem is a Ruby package that contains a library or an application. Rails itself is a Gem that is installed on JRuby. See GlassFish v3 Gem for more information.
