<strong>4 published articles covering Velocity</strong>
</p>
<blockquote>
<a href="http://www.webtechniques.com/archives/2001/09/serv/">Getting Up
to Speed with Velocity</a> is a really well written article by Jim
Jagielski about the merits of using a tool like Velocity.
</blockquote>
<blockquote>
Many people believe that Velocity can only be used in the context of web
applications. This excellent <a
href="http://www.javaworld.com/javaworld/jw-07-2001/jw-0727-templates.html">JavaWorld
article</a> by Leon Messerschmidt shows that the design of Velocity is
such that it can be used in a myriad of applications.

<blockquote>
The Java Developer Journal recently <a

edited version of the <a href="./ymtd/ymtd.html">YMTD article</a> by Jon
Stevens as the cover story for their July edition.

<section name="What is Velocity?">
<p>
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.
</p>
<p>
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 <a
href="http://java.sun.com/products/jsp/">Java Server Pages</a>
(JSPs) or <a href="http://www.php.net/">PHP</a>.
</p>
<p>
Velocity's capabilities reach well beyond the realm of web sites; for
example, it can generate SQL and PostScript and XML (see <a
href="./anakia.html">Anakia</a> 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. Velocity also provides template services for the
<a href="http://jakarta.apache.org/turbine/">Turbine</a> web application
framework. Velocity+Turbine provides a template service that will allow
web applications to be developed according to a true MVC model.
