What is Velocity?¶
Velocity is a Java-based template engine. It permits anyone to use a 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 its lifespan and providing a viable alternative to Java Server Pages (JSPs) or PHP.
Velocity's capabilities reach well beyond the realm of the web; for example, it can be used to generate SQL, PostScript and XML 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. For instance, Velocity provides template services for various web frameworks, enabling them with a view engine facilitating development of web applications according to a true MVC model.

Apache Velocity Projects¶
Apache Velocity offers the following projects:
Velocity Engine ‐ This is the actual templating engine which does all the work. If you came here because you heard about Velocity somewhere on the web, this is probably the right place to start.
Velocity Tools ‐ This project contains tools and other useful infrastructure to build web and non-web application using the Velocity engine. You will find e.g. code for Struts integration or the standalone VelocityViewServlet here.
