Velocity Template Engine is now released.
Combining contributions and improvements from throughout the
Velocity community, this version offers many new enhancements
features and fixes.
|
Major enhancements include :
-
Application programmers now can instantiate separate, independent
instances of the Velocity Template Engine or continue to use the
traditional singleton model.
-
Major improvements to Anakia and Texen.
-
The Velocimacro system can be configured to reload changed
VM libraries automatically when the macro definitions change.
Minor enhancements are too numerous to mention. Please see the
change log
for details.
Note: Starting with this release, the distribution will contain
two pre-built jars, one with external dependencies included, and one
without. Please see the WHY_TWO_JARS.txt note in the distribution
for more information.

Hey, Maybe We're On The Right Track After All...
Give this
a read. The latest version of Resin, a
popular servlet engine, has added what they call a "Velocity-like syntax" to their JSP
implementation. As they say on their site :
"The Resin-2.0.3 release allows an alternate JSP expression syntax similar to the Apache Velocity project that many find more maintainable than the JSP pointy brackets. Resin's syntax extension is compatible with the usual JSP features like tag libraries."
We do think that this is a step in the right direction for JSPs, making the page content easier to
write and maintain.
However, we want to emphasize to users that this isn't the same thing as using
Velocity - this is a small subset of the Velocity syntax which
was reimplemented in Resin.
Velocity is much more than an alternative syntax to the scriptlets and
tags found in JSPs - it's a full-featured templating engine, fully portable to any
J2EE servlet container, that offers many advanges over JSPs in the J2EE
web application environment. It also an excellent templating tool
for other kinds of applications written in Java.
So if you are interested in portable alternatives to JSP, we strongly
encourage you look deeper into what Velocity has to offer.
And if you must use JSPs and want to incorporate Velocity into your
current or new JSP-based web applications, take a look at our
Veltag JSP taglib which allows the full
power of Velocity in your JSPs.
Velocidoc Released
Velocidoc, a Velocimacro documentation tool modeled after
Javadoc, is now available. Use Javadoc-style comments in your
Velocimacro libraries, and use Velocidoc to generate HTML
documentation.
New Apache Site Generated with Anakia
The new web site of the
Apache Software Foundation
is now generated using
Anakia,
the Velocity-based XML transforamtion tool.
Take a look.
Need To Mix JSP and Velocity?
Take a look at a new contribution, a
Velocity taglib that lets you
use Velocity right in your JSPs.
4 published articles covering Velocity
Getting Up
to Speed with Velocity is a really well written article by Jim
Jagielski about the merits of using a tool like Velocity.
Many people believe that Velocity can only be used in the context of web
applications. This excellent JavaWorld
article by Leon Messerschmidt shows that the design of Velocity is
such that it can be used in a myriad of applications.
The Java Developer Journal recently published an
edited version of the YMTD article by Jon
Stevens as the cover story for their July edition.
The Sun Dot-Com Builder developer information site has a "Best Practices" product profile on Velocity. Check it out
here. Thanks Sun!
4 Products/Projects Now Depend on Velocity
Gentleware, Xadra and Vamp have built products which depend on Velocity.
J/Top, a server monitoring project, also uses Velocity for email output
formatting.
We have listed them on our ever expanding Powered By Velocity page.
5 Web Frameworks Now Support Velocity
Turbine, JPublish, Melati, Maverick and WebWork
all support Velocity.

What is Velocity?
|
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.
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. Velocity also provides template services for the
Turbine web application
framework. Velocity+Turbine provides a template service that will allow
web applications to be developed according to a true MVC model.

Where do I get releases?
|
The current release version is version 1.1
The release distribution is available in both tar.gz and zip
formats, and are found here.
The latest release candidate, verion 1.2-rc1 can be found
here.
|
|
Where do I get nightly snapshots?
|
Nightly snapshots of the Velocity CVS can be found
here.
These are meant to provide easy access to the actual project CVS tree.
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.
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!) Public CVS
access is also available.

|
How do I contribute, give feedback, fix bugs and so on?
|
The Velocity project really needs and appreciates any contributions,
including documentation help, source code and feedback. Suggested
changes should come in the form of source code and/or very detailed
and constructive feedback.
