This book will get you up and running with Grails by putting it to use in constructing an original, working application from start to finish. more »
Groovy Recipes
If you're a busy Java professional who needs quick solutions to everyday problems, then Groovy Recipes is for you. The Groovy language and Grails web framework give you seamless integration with your legacy Java code while adding the flexibility and dynamism of a scripting language and giving you modern, agile, time-saving techniques. Groovy allows you to write code the way you always thought you should - you'll never look at Java the same way again. more »
Grails Persistence with GORM and GSQL
Unique to the popular Grails web framework is its architecture. While other frameworks are built from the ground up, Grails leverages existing and proven technologies that already have advanced functionality built in. One of the key technologies in this architecture is Hibernate, on top of which Grails builds its GORM (Grails Object Relational Mapping) model layer. This provides Grails a persistence solution.

This firstPress book covers Grails persistence with GORM, from defining your first model to the nature of transactions and advanced Hibernate querying. Other APIs and tools such as GSQL (Groovy SQL) are covered as well, as needed, to empower your Grails persistence efforts. more »

Beginning Groovy, Grails and Griffon
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. more »
Grails 2: A Quick-Start Guide
Grails is a full-stack web development framework that enables you to build complete web applications in a fraction of the time and with less code than other frameworks. Grails uses the principle of convention over configuration and the dynamic Groovy programming language.

This revised and updated new edition shows you how to use Grails by iteratively building a unique, working application. By the time you're done, you'll have built and deployed a real, functioning website. Using this hands-on, pragmatic approach, you'll explore topics such as Ajax in Grails, custom tags, and plugins. You'll dig into Grails' powerful view technology, Groovy Server Pages, and see how you can easily leverage the help offered by scaffolding to create custom user interfaces faster than you would have thought possible. Along the way, you'll learn about domain classes, controllers, and GSP views. And you'll see how Grails enables you to use powerful frameworks such as Spring and Hibernate. more »
