Java-based template engine for web application
Velocity is a Java-based template engine. It permits anyone to use
the simple yet powerful template language to reference objects
defined in Java code.
When Velocity is used for web development, Web designers can work in
parallel with Java programmers to develop web sites according to the
Model-View-Controller (MVC) model, meaning that web page designers
can focus solely on creating a site that looks good, and programmers
can focus solely on writing top-notch code. Velocity separates Java
code from the web pages, making the web site more maintainable over
the long run and providing a viable alternative to Java Server Pages
(JSPs) or PHP.
