Jruby is an agile open source project that lets Java developers
integrate and use the popular Ruby on Rails to build Web applications.
The book author, JRuby project co-leader Ola Bini, is uniquely
positioned to write about this, as he brings a unique blend of knowledge
surrounding JRuby internals, the Java programming language and the Ruby
programming language, along with solid experience building
enterprise-level Rails applications.
This book provides complete coverage on how to use JRuby to create web
applications faster and more efficiently, while continuing to take
advantage of the vast power of the Java platform. The book also provides
several real-world projects that illustrate the crucial specifics you
need to know about the interaction of Java and Ruby. In addition, it
offers helpful, practical instruction and discussion on how web
applications can be deployed using a variety of popular servers such as
Apache and Mongrel.
