Como receber bytes (de video) pela servlet?

class UploadToServer extends Thread
    {
        public void run()
        {
            Upload();
        }

        public void Upload ()
        {

            HttpConnection http = null;
            OutputStream oStrm = null;
            InputStream iStrm = null;
            boolean ret = false;

            String url = "127.0.0.1/ServerVideo";

            try {

                http = (HttpConnection) Connector.open(url);
                oStrm = http.openOutputStream();

                http.setRequestMethod(HttpConnection.POST);
                http.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

                byte data [] = output.toByteArray();
                oStrm.write(data,0,data.length);

                iStrm = http.openInputStream();

                //ret = processServerResponse(http, iStrm);

                if (iStrm != null)
                    iStrm.close();

                if (oStrm != null)
                    oStrm.close();

              iStrm = http.openInputStream();      
     
              //ret = processServerResponse(http, iStrm);
              if (iStrm != null)
              iStrm.close();

              if (oStrm != null)
              oStrm.close();

              
              if (http != null)
                  http.close();

            }
                            catch (IOException e)
            {
                e.printStackTrace();
            }
             
        }
        
        
    }

String acct = req.getParameter("string");
