Velocity

Description:

A Java-based template engine, Velocity permits developers to use a simple yet powerful template language to reference objects defined in Java code. Velocity allows Web designers to work in parallel with Java programmers to develop web sites according to the Model-View-Controller (MVC) model. Functionally, this means that designers can focus on creating a site that looks good, while programmers focus on writing top-notch code. Velocity separates Java code from the web pages, making the web site more maintainable over its lifespan and providing a viable alternative to Java Server Pages (JSPs) or PHP.

Velocity's capabilities reach well beyond the realm of the web. Use it to generate SQL, PostScript and XML from templates as either a standalone utility for generating source code and reports, or as an integrated component of other systems.
