If you’re interested in JRuby, you probably don’t need a tutorial on Ruby, Rails, or Java – you just need to know how to get things done.
This Cookbook offers practical solutions for using the Java implementation of the Ruby language, with targeted recipes for deploying Rails web applications on Java servers, integrating JRuby code with Java technologies, developing JRuby desktop applications with Java toolkits, and more. Using numerous reusable code samples, JRuby Cookbook shows you how to:
Install and update JRuby on Windows, Mac OS X, and Linux, and IDEs such as NetBeans and Eclipse
Package and deploy Rails apps on Java Servlet containers and Java EE application servers, including JBoss, Tomcat, and GlassFish
Integrate Ruby and Rails applications with popular Java EE technologies such as JMS, JMX, JPA, Spring, and Hibernate
Develop desktop and client applications with cross-platform Java UI technologies and toolkits such as Swing, SWT, and Java 2D
Maximize the flexibility of your testing and build environment, using both existing Java-based tools such as Ant and Maven and newer Ruby-based tools such as Rake, Raven, and Buildr
