To facilitate rapid application development and deployment, Sun GlassFish Enterprise Server v3 Prelude supports a variety of scripting languages. The use of scripting languages enables Enterprise Server to be applied beyond developments that are centered on Java technology. Supported scripting languages include the following:
JRuby and Rails: A scripting language and a framework for developing web applications
Grails: A web application framework that leverages the Groovy programming language and complements Java web development
jMaki: A framework for creating Ajax web applications
Support for these scripting languages is provided by components that are available through Update Tool.
