How to customize the administration console URL in wecenter portal

By default, we can access the webcenter portal administration console from the following URL
http://www.app-server:port/applicaiton-context_root/admin.

We can customize it by making the following changes to the web.xml

  <servlet>
    <servlet-name>PortalAdminServlet</servlet-name>
    <servlet-class>oracle.webcenter.portalwebapp.servlet.PortalAdminServlet</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>PortalAdminServlet</servlet-name>
    <url-pattern>/desired-url</url-pattern>
  </servlet-mapping>
