URLConnection : Kindly Help URGENT

Question

I need to upload large size of data to the server in minimum possible time and in chunks. I have used multipart-upload API but that does not solve my purpose.
Now am trying to send data through URL as per the following code.. But again i have no luck in this context .
CAN I POST DATA TO THE SERVER BY THE FOLLOWING CODE ANYHOW OR SOMETHING ELSE
URL loUrl = new URL("http://172.20.10.51:8080/UploadServlet/Upload");
          RandomAccessFile loFile = new RandomAccessFile("D:/BIDS.zip" , "r") ;
     URLConnection urlConn;
     DataOutputStream printout;
     urlConn = loUrl.openConnection();
     urlConn.setDoInput (true);
     urlConn.setDoOutput (true);
     urlConn.setUseCaches (false);
     urlConn.setRequestProperty
     ("Content-Type", "application/x-www-form-urlencoded");
     printout = new DataOutputStream (urlConn.getOutputStream ());
     int loRead = loFile.read() ;
     while(loRead != -1) {
               printout.write(loRead);
     printout.flush ();
     printout.close ();

Nopes not at all am not expecting any complete codes rather just an idea about why this particular code is not working for me or if so what else i could have edited to make it work .
Am inviting assistance here and not any altercations .
But still thanks for ur kind consent .
