What is Velocity?</h2> | |
<p> Velocity is a Java-based template engine. It permits anyone to use a 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 its | |
lifespan and providing a viable alternative to | |
<a class="externalLink" href="http://java.sun.com/products/jsp/">Java Server Pages</a> | |
(JSPs) or | |
<a class="externalLink" href="http://www.php.net/">PHP</a> | |
. </p> | |
<p> Velocity's capabilities reach well beyond the realm of the web; for example, it can | |
be used to generate SQL, 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. | |
For instance, Velocity provides template services for the | |
<a class="externalLink" href="http://jakarta.apache.org/turbine/">Turbine</a> | |
web application | |
framework, together resulting in a view engine facilitating development of web | |
applications according to a true MVC model. </p> | |

<div class="section"><h2><a name="Where_do_I_get_releases"></a> | |
Where do I get releases?</h2> | |
<p> The current stable release version is version 1.6.1. </p> | |
<p> The release distribution is available as a combined source/binary distribution in | |
<code>tar.gz</code> and | |
<code>zip</code> formats, and can be downloaded through the | |
<a class="externalLink" href="http://velocity.apache.org/download.cgi"> | |
Apache Mirror system</a> | |
. </p> | |
<p> The Velocity jars are also available through the | |
<a class="externalLink" href="http://repo1.maven.org/maven2/org/apache/velocity/">central Maven | |
repository</a> | |
. </p> | |

<div class="section"><h2><a name="Where_do_I_get_nightly_snapshots"></a> | |
Where do I get nightly snapshots?</h2> | |
<p> Nightly snapshots of the Velocity subversion source code tree can be found | |
on our <a class="externalLink" href="http://vc.apache.org/snapshots/velocity/">nightly snapshot site</a> | |
. </p> | |
<p><b>Caveat!</b> | |
These snapshots are generated automatically from the project source code repository. As | |
this is our live development workspace, there are no guarantees as to what you will | |
find there, although we do our best to maintain a buildable source tree. If you are | |
looking for the stable supported release, please use the current release of | |
Velocity. </p> | |
<p><b>Please be aware that these snapshots are not official | |
releases of Apache Velocity software. They are provided for | |
developer convenience only!</b> | |
</p> | |
<p> If you are willing to risk getting dirty, we invite you to try the nightly snapshot to | |
see the current state of affairs. (and help out!) | |
