Groovy is a dynamic language for the JVM that integrates seamlessly with the Java platform. It offers a Java-like syntax, with language features inspired by Smalltalk, Python or Ruby, and lets your reuse all your Java libraries and protect the investment you made in Java skills, tools or application servers.
Uses of Groovy include the Grails web application framework, XWiki, and Spring 2.0 scripting integration.
2007 is shaping up to be a important year in the evolution of the Groovy language. A number of books either have been released (Groovy in Action) or a slated for publication this year. Last month Big Sky Technologies announced the launch of the aboutGroovy.com portal and the funding of Jochen Theodorou to work full time on Groovy development.
