If you're interested in JRuby, you probably don't need a turorial 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

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

Finally an advanced book on JRuby - 2008-12-16
Reviewer Rating:
Having heard about this book several months before its publication, I was very happy to find that it had exceeded my expectations. As a Java developer very interested in Ruby, I was somewhat surprised at the lack of printed documentation on JRuby. I found this book to be very up-to-date, practical, and easy to follow, with examples that I could immediately apply. Particularly useful for me were the sections on setting up your environment with JRuby, Rails, and your preferred IDE, as well as deploying rails with various application servers. The instructions for all the main app servers on the market were extremely clear, and I was able to get things up and running in very short order. Also, I found the chapter on Enterprise Java integration to be especially useful, as it provided specific recipes for using JNDI, JMS, integration with Spring and Hibernate frameworks. I would highly recommend this book for any JRuby enthusiasts out there, looking for a solid and comprehensive springboard into the technology.
Thank you Justin and Henry!

a great start, but now I want more - 2009-09-12

O'Reilly's Cookbook series is well known for providing short, pithy instructions for solving practical real-world issues in a well-organized recipe format. The JRuby Cookbook upholds that tradition, and I've found it a particularly invaluable source for help on JRuby-specific topics like integrating your JRuby code with legacy Java libraries or with services like JMS and JNDI. Clear, well-written JRuby-specific docs can be hard to come by on the web, so this book was a real life-saver for me. I frequently found myself wanting more though. The present edition is a great start, but those are big and complex topics, and more recipes, with more example code, would make it even better. So I'm appreciating the current edition, and at the same time hoping there will be a second, expanded one soon.
