Product Description


Web frameworks are playing a major role in the creation of today's most compelling web applications, because they automate many of the tedious tasks, allowing developers to instead focus on providing users with creative and powerful features. Java developers have been particularly fortunate in this area, having been able to take advantage of Grails, an open source framework that supercharges productivity when building Java–driven web sites. Grails is based on Groovy, which is a very popular and growing dynamic scripting language for Java developers and was inspired by Python, Ruby, and Smalltalk.

Beginning Groovy and Grails is the first introductory book on the Groovy language and its primary web framework, Grails.

This book gets you started with Groovy and Grails and culminates in the example and possible application of some real–world projects. You follow along with the development of each project, implementing and running each application while learning new features along the way.

What you’ll learn

• Understand the basics of the open source, dynamic Groovy scripting language and the Grails web framework.
• Capitalize upon Grails’ well–defined framework architecture to build web applications faster than ever before.
• Improve your web application with cutting–edge interface enhancements using Ajax.
• Use Grails’ object–relational mapping solution, GORM, to manage your data store more effectively than ever before.
• Take advantage of Groovy to create reporting services, implement batch processing, and create alternative client interfaces.
• Deploy and upgrade your Grails–driven applications with expertise and ease.
• Discover an alternative client in Groovy as well.

Who is this book for?

Java and web developers looking to learn and embrace the power and flexibility offered by the Grails framework and Groovy scripting language

Reader Reviews
Let me start by saying "Beginning Groovy and Grails" is the book that the Grails community has been clamoring for. Two very good books kicked off the Grails revolution ("Definitive Guide to Grails" and "Getting Started with Grails"), but both predate the 1.x version of Grails by many dot-versions and many years (as of the time of this review, August 2008). BGG will certainly have worthy competition on the bookshelf before long, but right now it is the book that we all have been waiting for. Luckily, it easily lives up to the heightened expectations. After reading BGG cover to cover, it seems to break naturally into three sections: Core Groovy, Core Grails, and Ancillary Grails. This division is mine, not the authors; the table of contents lists 13 chapters with no explicit section breaks. (Whether the three sections correspond to the three authors is an interesting question -- the tone of voice and writing style is consistent across the entire book.) The first three chapters do an admirable job of covering the Groovy language from the basics to advanced topics. Groovy offers lots of syntactic sugar that might initially catch a Java programmer off-guard. These features, once you've seen them, dramatically reduce the lines of code you have to write. But more than that, there are some fundamentally new features in Groovy that don't have an easy match in Java. Builders, Expandos, metaprogramming, and DSLs are all discussed in these early chapters. While you don't have to use these features yourself to be successful in Grails, it certainly helps the reader understand how much of the Grails "magic" occurs under the covers. The next three chapters (Introduction to Grails, Building the User Interface, and Building Domains and Services) hit the Core Grails features hard. These 150 pages do a great job of walking you through the basics of getting a Grails application up and running with a minimum of effort. They also make testing feel like a natural part of the development process (which it should be!). Rather than having a single chapter dedicated to testing, each new topic organically includes testing as a way to validate that the new code does what it promises to do. The remaining chapters (Security, Ajax, REST, Reporting, Batch Processing, Deploying, and Alternative Clients) make up close to half the book. Each chapter covers the subject material as advertised, including working sample code. Not every Grails application will use every feature discussed here, but I still found a clever snippet of code here or a nice explanation of a general concept that rewarded me for reading every chapter. Overall, "Beginning Groovy and Grails" delivers on its title -- if you are new to either (or both) technologies, you will be up and running before you know it. But don't be fooled by the title; even though it has "Beginning" in it, this book doesn't shy away from the advanced topics, either. This isn't a completist volume. Rather, it is a broad survey of the Groovy and Grails ecosystem. Christopher, Joseph, and Jim covered a lot of ground in an easy, readable way. I highly recommend it.
