The Velocity Template Engine lets you render data from within applications and servlets. Primarily used to develop dynamic, servlet-based Websites, Velocity's clean separation of template and Java code makes it ideal for Model 2-style Model-View-Controller (MVC) Web development. As a general template engine, Velocity suits many other purposes, such as code generation, XML generation and transformation, and textual stream processing. This article introduces the Velocity Template Language (VTL) and provides examples of how to use the Velocity engine, including how to generate Web content in a Java servlet environment.
