Rails Powered by the GlassFish Application Server

This paper introduces JRuby, JRuby on Rails, and the GlassFish application server. It presents a traditional Ruby-on-Rails application deployment, describes an alternative using the GlassFish application server, and explains the various options for deploying JRuby applications on GlassFish. Many developers see the GlassFish application server as the superior solution for developing and deploying JRuby-on-Rails applications chiefly due to the following advantages: The developer can develop in the same environment in which he or she deploys, One can deploy multiple applications in a GlassFish instance that is already running. GlassFish can handle multiple requests by maintaining JRuby runtimes and database connections in pools.
