How do I map multiple URLs to point to a single page created with the JavaServer Pages ^TM technology (JSP ^TM page)?

1. How do I map multiple URLs to point to a single page created with the JavaServer Pages ^TM technology (JSP ^TM page)?

The web deployment descriptor maps URLs to web components. For example, the Java Pet Store sample application maps all URLs matching /control/* to MainServlet in web.xml like this:

                         
<web-app>
  <display-name>WebTier</display-name>
  <description>no description</description>

  <servlet>
    <servlet-name>webTierEntryPoint</servlet-name>
    <display-name>centralServlet</display-name>
    <description>no description</description>
    <servlet-class>
  com.sun.j2ee.blueprints.petstore.control.web.MainServlet
    </servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>webTierEntryPoint</servlet-name>
    <url-pattern>/control/*</url-pattern>
  </servlet-mapping>

  <!-- web.xml continues... -->
