How do I use Groovy with JSF?

Groovy (http://groovy.codehaus.org), inspired by Ruby, Smalltalk, and Python, is a another popular programming language for the Java Virtual Machine. Groovy is dynamically typed, and Groovy code can be more concise than the equivalent Java code because you can omit types of variables and parameters.

Almost any Java code is legal Groovy. That makes it simple to get started with Groovy in your JSF applications: Change the suffix of your code from .java to .groovy, and use the Groovy compiler to compile your Groovy code to a .class file. JSF deals in .class files, so it doesn’t know, or care, that you are using Groovy to generate them.
