Grails is a full stack framework for developing Web applications on the Java platform. It builds on the concepts introduced by frameworkds like Rails, Django, and TurboGears, but builds on established Java technologies like Spring and Hibernate. It includes an easy-to-use object relational mapping (ORM) layer, an expressive view technology, a controller layer, a command line scripting environment, an embedded Jetty container which is configured for on-the-fly reloading, dependency injection, support for internationalization (i18n), and a transactional service layer.
