You need to use FreeMarker to
write
templates that can reference variables, object properties, and DOM
Node objects.
You must download the latest version of FreeMarker, and place the
FreeMarker JAR in your
project’s classpath. Go to the FreeMarker download
page at http://www.freemarker.org/freemarkerdownload.html,
and download the FreeMarker 2.3 distribution. After you untar and
unzip the distribution, you will find a
freemarker.jar file in the
lib directory; place this file in your
project’s classpath.
If you have a Maven project that needs to use FreeMarker, add a
dependency on FreeMarker with the following section in
project.xml:
<dependencies>
<dependency>
<id>freemarker</id>
<version>2.3</version>
</dependency>
....other dependencies...
</dependencies>To learn more about FreeMarker, visit the FreeMarker web site (http://www.freemarker.org/).
To participate in the FreeMarker community, join the FreeMarker users or developers list (http://sourceforge.net/mail/?group_id=794).
