Java professionals long the productivity gains a framework like Ruby on Rails provides, without having to leave the Java Platform. Grails provides this missing link by bringing the best aspects from Grails while embracing the Java platform and language itself. Grails is an open source Java/Groovy-based Rails-like framework that gives dynamic Java a boost; so, Java developers now have a viable Java-based solution instead of considering the non-Java-based Ruby on Rails, which can create more problems than it solves. Grails, sometimes called Groovy on Rails, is an emerging area of much interest with already anticipated available support from such key Java projects as Spring, Oracle, and more.

The Definitive Guide to Grails, Second Edition, will be the first and definitive book on Grails written by the founder and leads of Grails.
