JRuby Cookbook--New from O'Reilly: When Ruby Meets Java

Press release: November 21, 2008

JRuby Cookbook Sebastopol, CA—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. The JRuby Cookbook (O'Reilly, US $34.99) by Justin Edelson and Henry Liu 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.

"To fully leverage JRuby, you must be able to move freely between the Java and Ruby domains. In writing the JRuby Cookbook, we had in mind a reader with some understanding of both languages," note Edelson and Liu. "The purpose of the recipes in this book is not to educate you on some preexisting Java or Ruby capability, but instead to explain how to use JRuby within the context of, or as an enhancement to, these existing capabilities."

Using numerous reusable code samples, the 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

The JRuby interpreter combines Ruby's simplicity and ease of use with Java's extensive libraries and technologies, a potent blend that opens new possibilities for Ruby, Rails, and Java. This Cookbook helps you take full advantage of JRuby's potential.

"The JRuby Cookbook is an excellent book for any polyglot who is trying to bridge the gap between Java and Ruby. It provides solutions to specific problems developers face in both their development and testing environments, along with the applications they're building."
- Bob McWhirter, Research & Prototyping, Red Hat Middleware
