Tomcat /manager commends from Servlet

Question

Hi all,
I asked a question regarding the excution of Tomcat /manager commands from a servlet and I got no replies... :(
Well, I never found a way to directly execute the /manager commands from the servlet (API) - but I did (eventually) get it working via URLConnection. Now, I've decided to release my (simple) code here so that it may help others!
This code searches for a context and then checks if it is running, if it is found not to be running it will attempt to start it. (tested and found to work under Tomcat 5.0.28).
  String
    protocol  = "http",
    host      = "localhost",
    usr       = "usr",
    pwd       = "pwd",
    context   = "/myapp";
  int port = 80;
  URL list = new URL(protocol,host,port,"/manager/list");
  URLConnection c = (URLConnection)list.openConnection();
  String encs = new sun.misc.BASE64Encoder().encode((usr+":"+pwd).getBytes());
  c.setDoInput(true);
  c.setRequestProperty("Authorization", "Basic " + encs);
  c.connect();
  BufferedReader buf = new BufferedReader(new InputStreamReader(c.getInputStream()));
  String line;
  while ( (line = buf.readLine()) != null )
     * Search for the /workpackages context
    if ( line.startsWith(context+":") )
       * Found the context
       * Now make sure that it's running
      if ( line.indexOf("running") > 0 )
         * Context /workpackages found to be running!
          System.out.println("Context ["+context+"] - Running!");
      else
         * Context found NOT to be running!
         * Try and start the context!
        buf.close();
        System.out.println("Context ["+context+"] - Attempting to start context...");
        URL start = new URL(protocol,host,port,"/manager/start?path="+context);
        c = (URLConnection)start.openConnection();
        c.setDoInput(true);
        c.setRequestProperty("Authorization", "Basic " + encs);
        c.connect();
        buf = new BufferedReader(new InputStreamReader(c.getInputStream()));
        while ( (line = buf.readLine()) != null ) System.out.println(line);
      break;
notes:
The buffer reading after both commands seems to be required! I don't know why... But I found that without them, the manager commands seem to be ignored!?!? odd!
Well, I hope this helps someone...

thanx
but when i am Deploying directory or WAR file located on server
where is this XML Configuration file,
so that i can fill in the text box-XML Configuration file URL
and secondly in tomcat 5.5.4
there is no context path described in server.xml
so where is this in 5.5.4
