    *
  1. Compile the servlet as described in the document for this package. * *
  2. Register the servlet in the weblogic.properties file by adding * (or uncommenting) the following lines: * 
       
 *    weblogic.httpd.register.snoop=examples.servlets.SnoopServlet
 *
    * *
  3. Call the servlet from a web browser using the URL: * 
     *    http://wlhost:port/snoop
 *
    * where wlhost is the host name of your server and port is the http listen port. * For example, use this URL if you are running the default setup on a local machine: * 
     *    http://localhost:7001/snoop
 *
