Mastering Apache Velocity (PDF)

A comprehensive tutorial on how to use the power of Velocity 1.3 to
build Web sites and generate content

Designed to work hand-in-hand with Apache Turbine, Struts, and
servlets, Velocity is a powerful template language that greatly
enhances the developer's ability to customize Web sites. It
separates Java code from the Web pages, making a site more
maintainable. Because of this, it is a viable alternative to JSPs
and PHP and is expected to become the standard template engine. In
addition to its use with Struts and Turbine, Velocity can also be
used to generate Java and XML source code, XML schemas, HTML
templates, and SQL code.

Even with all its promise, finding expert instructions on how to
properly program with this language has been difficult. This
code-intensive tutorial gives you all the tools you'll need.

It begins by quickly bringing you up to speed on all of the
Velocity fundamentals and the Velocity Template Language. You'll
then learn how to apply Velocity in a variety of areas with the
help of richly detailed code examples. Additionally, you'll be
taken through the steps of building a complete application in order
to see how you can utilize all of the techniques and technologies
discussed in the book. Covering the latest features of Velocity
1.3, Mastering Apache Velocity shows you how to:

* Build Java-based Web sites with Struts, servlets, Turbine, and
other open-source tools

* Generate a wide variety of Web content and code, including Java,
XML, SQL, and Postgres
