org.apache.velocity.tools.view.VelocityView

The class provides the following features:

renders Velocity templates
provides support for an auto-loaded, configurable toolbox
provides transparent access to the servlet request attributes, servlet session attributes and servlet context attributes by auto-searching them
logs to the logging facility of the servlet API

VelocityView supports the following configuration parameters in web.xml:

org.apache.velocity.toolbox: Path and name of the toolbox configuration file. The path must be relative to the web application root directory. If this parameter is not found, the servlet will check for a toolbox file at '/WEB-INF/tools.xml'.
org.apache.velocity.properties: Path and name of the Velocity configuration file. The path must be relative to the web application root directory. If this parameter is not present, Velocity will check for a properties file at '/WEB-INF/velocity.properties'. If no file is found there, then Velocity is initialized with the settings in the classpath at 'org.apache.velocity.tools.view.velocity.properties'.

There are methods you may wish to override to access, alter or control any part of the request processing chain. Please see the javadocs for more information on :

{@link #setContentType} :
for changing the content type on a requestby request basis
{@link #requestCleanup} :
post rendering resource or other cleanup
{@link #error} :
error handling
