Monkeybars This is a library enabling you to use Swing from JRuby.

It allows you to continue using the GUI editing tools you are used to but makes it easy to write all your application logic in pure Ruby. In fact, with most editors you’ll never even have to look at the Java.

For more information, please see www.monkeybars.org.

Rawr gives you a packaging and deployment system for your JRuby application. Rawr can package your app into an executable jar and provides you integration with existing Java IDE's.
