Velocity is a Java-based template engine. It permits web page designers
to use simple yet powerful template language to reference objects
defined in Java code. 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.
Velocity's capabilities reach well beyond the realm of web sites; for
example, it can generate SQL and PostScript and XML (see Anakia for more information on XML transformations)
from templates. It can be used either as a standalone utility for
generating source code and reports, or as an integrated component of other
systems. When complete, Velocity will provide template services for the
Turbine web application
framework. Velocity+Turbine will provide a template service that will allow
web applications to be developed according to a true MVC model.
