Comments and Reviews
—Bharat Ruparel Senior information architect America's Test Kitchen
This book is an excellent resource for JRuby and will without a doubt facilitate JRuby adoption in Java-centric enterprises.
—Fred Daoud Author, "Stripes...and Java Web Development Is Fun Again," and "Getting Started with Apache Click"
This book makes a compelling case for JRuby. A must-have to bring some Ruby goodness to your Java powerhouse.
—Gale Straney Senior software design engineer Tektronix
This is one of those books that you don’t want to put down and you can’t wait to get back to. For a technical publication, that is extremely rare. After reading this book, I can say I have a very good understanding of what JRuby is, how it interacts with Java, and a working knowledge of many of the supporting tools to accomplish a wide range of tasks. The way this book is organized, it makes a great reference for future development.
—Geoff Drake Owner Managed Design
This book will open the eyes of any Java programmer who wants to take their art to the next level. Read it.
—Vladimir Sizikov Senior Engineer Oracle
I really liked the clear structure of the book and all the covered libraries/dependencies (like Rake, Ant, Maven, testing frameworks). This clearly outlines the whole JRuby universe so that new users will immediately see what’s available and how to start using it.
—Pinit Asavanuchit Intersol Consulting Co., Ltd.
My JRuby apps will go live in two weeks. Without your book and the Ruby community, I would never have gotten this far.
—Kent R. Spillner
I was floored by the amount of technical detail the authors managed to cram in here! And they did it with such an approachable and readable tone that this book was both easy and fun to read. I can’t remember the last technical book that did that for me. The breadth of coverage is astounding, too.
—Peter Lind Technical Consultant Valtech
I was very happy to discover the JRuby project, my favorite programming language running on what’s probably the best virtual machine in the world. This book really covers every in and out of this fantastic project.
