Описание: Ruby on Rails pioneered the innovative coupling of a powerful programming language and an opinionated framework that favors sensible defaults over complex configuration. Developers praise the revolutionary Rails framework (and rightfully so) for its revival of productivity, but many organizations aren’t yet ready to stray from the safety of Java. So if we can achieve similar productivity and (shhhh!) fun with a more Java-centric solution, what's not to like? Grails makes that idea a reality. And the more conservative businesses should find additional comfort knowing that Grails applications play nicely with their existing Java code, because Grails applications are written in Groovy – a dynamically-typed scripting language that stands to soon become a Java standard.
