Today, what does a developer do when they want to start a project from scratch? Do I go with JSF? Ruby on Rails? JRuby? Groovy on Rails? Struts 2? GWT? Flex?

Grails aims to bring the "coding by convention" paradigm to Groovy. It's an open-source web application framework that leverages the Groovy language and complements Java Web development. You can use Grails as a standalone development environment that hides all configuration details or integrate your Java business logic. Grails aims to make development as simple as possible and hence should appeal to a wide range of developers not just those from the Java community.
