The Grails framework seamlessly and transparently integrates and interoperates with Java, the JVM, and existing Java EE containers. Apache Groovy is a language for the Java platform designed to enhance developers' productivity. It is an optionally-typed and dynamic language but with static-typing and static compilation capabilities.
