BE THE CODER > Template Engines > Velocity Examples

Apache Velocity is a free, simple and powerful template engine written in 100% pure Java. This requires the libraries velocity-1.7.jar, oro-2.0.8.jar, commons-lang-2.4.jar, commons-collections-3.2.1.jar, commons-logging-1.1.jar, log4j-1.2.12.jar to be in classpath. The following example shows loading a Velocity template from an input stream.
