[[Home|&raquo; JRuby Project Wiki Home Page]] <h1>JRuby on Rails</h1> You can use JRuby with [http://www.rubyonrails.org/ Ruby on Rails]. JRuby gives Rails the power and functionality of the Java Platform, providing it with: * Excellent garbage collection for endless uptimes * Hotspot profiled dynamic optimizations for great performance * Access to the Java ecosphere for additional technology options * Deployment to Java application servers for ubiquity __TOC__ ===Getting Started=== Get started with these tutorials: *[http://blog.emptyway.com/2008/04/08/120-seconds-guide-to-jruby-on-rails| 120-second guide to JRuby on Rails] *[http://thenice.tumblr.com/post/133345213/deploying-a-rails-application-in-tomcat-with-jruby-a| Deploying a Rails application in Tomcat with JRuby: A concise tutorial] * [[JRuby on Rails with Spring|JRuby on Rails with Spring]] - zero to <code>.war</code> file with Spring and Maven. * "Porting" the Depot Application To Jruby, [http://tompurl.com/2010/03/02/running-the-depot-application-with-jruby/ Parts 1] and [http://tompurl.com/2010/03/25/running-depot-on-tomcat/ 2]: These tutorials show you how to make the Depot application from "[http://www.pragprog.com/titles/rails3/agile-web-development-with-rails-third-edition Agile Web Development with Rails, Third Edition]" work with Jruby. === Deployment === ==== War File Deployment ==== If you don't use a traditional Ruby application server like [http://mongrel.rubyforge.org/ Mongrel], you can use a Java application server. To deploy to a Java app server, you can use the tool <a href="{{project warbler page Home}}">Warbler</a> to bundle your Rails application in a Java Web Application Archive (<tt>.war</tt> file). (Warbler is a minimal, flexible, Ruby-like way to create a <tt>.war</tt> file.) Once you have a <tt>.war</tt> file, you can deploy to any Java app server using its war deployment mechanism.

The Glassfish gem wraps the essential technologies in 3 MB and allows you to run your application using a traditional approach, as if you were running Mongrel, Rack, and so on. A brief tutorial can be found here:<br/> [[JRuby on Rails with Glassfish Gem]].
