Parameters
url
The URL to import.

The supplied URL rendered as a String.
This method takes an arbitrary URL or URI and renders it as a String. This tool can also be used to import local .vm resources without sharing the current velocity-context (as opposed to the #parse directive).

The servlet configuration (web.xml ) must be modified to include a reference to the VelocityViewServlet (or subclass thereof) which will perform the rendering. All *.vm files are mapped to this servlet which will populate the 'context' with Request, Session, and Application scopes plus any additional tools specified in the toolbox.xml file. The servlet will use this contextual information and the Velocity Engine to render the template file.
 
Note: Additional functionality can be achieved through subclassing the VelocityViewServlet, and will be discussed further in the VelocityLayoutServlet below.
web.xml

<!-- Define Velocity template compiler -->
<servlet>
  <servlet-name>velocity</servlet-name>
  <servlet-class>
    org.apache.velocity.tools.view.servlet.VelocityViewServlet
  </servlet-class>

  <!-- 
    Unless you plan to put your toolbox.xml and velocity.properties
    under different folders or give them different names, then these
    two init-params are unnecessary as of VelocityTools 1.3.  The
    VelocityViewServlet will automatically look for these files in
    the following locations.
  -->
  <init-param>
    <param-name>org.apache.velocity.toolbox</param-name>
    <param-value>/WEB-INF/toolbox.xml</param-value>
  </init-param>

  <init-param>
    <param-name>org.apache.velocity.properties</param-name>
    <param-value>/WEB-INF/velocity.properties</param-value>
  </init-param>
</servlet>

<!-- Map *.vm files to Velocity -->
<servlet-mapping>
  <servlet-name>velocity</servlet-name>
  <url-pattern>*.vm</url-pattern>
</servlet-mapping>
