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. T he year 2005 was a traumatic year for the Java web application development com- nity. It was under fire for the unnecessary "fat” architecture of Java Platform, Enterprise Edition (Java EE) systems compared to the new kids on the block like Ruby on Rails and Django. The search began for Java´s answer to these frameworks. I had an existing product that was heavily invested in Java frameworks such as Spring and Hibernate, but because I had been involved with the Groovy team for a while, I knew we could create the solution that people were looking for. Hence, Grails was born. I knew Groovy itself was a phenomenal piece of technology that combined the best of the dynamic language worlds and Java. Innovation has been rife within the Groovy community since the early days with its builder concept. It had inspired other languages, and more recent languages such as ActionScript 3 and ECMAScript 4 had adopted its support for mixed typing. Groovy had proven to me that you can mix a dynamically typed language like Groovy with a statically typed language like Java in the same code base and get the best of both worlds without incurring the cost of context switching. Beginning Groovy and Grails introduces Java developers to this popular framework and scripting language by guiding readers through the creation of a series of real-world projects. Each project introduces a new facet of Grails and Groovy, and affords readers the ability to download and experiment with the code. Authored by industry veterans Christopher Judd, Joseph Faisal Nusairat, and Jim Shingler, readers are treated not only to profound knowledge of the topic, but also to considerable insight shared as a result of the authors´ combined decades of Java experience.
