Listening for HttpURLConnections ?

Question

hi,
I have implemented a client opening a HttpURLConnection to send an image to a servlet.
I would like to know how should be the code on the server, listening for httpURLconnections... can you give me some tip ?
Here is the client code... What I need is the server code... I want to save the file to hard disk, when a post is performed.
thanks
URL url;
          HttpURLConnection connection = null;
          try {;
               //Create connection
               url = new URL("http://localhost:8080/Sender");
               connection = (HttpURLConnection)url.openConnection();
               connection.setRequestMethod("POST");
               connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
               connection.setRequestProperty("Connection","Keep-Alive");
               connection.setUseCaches (false);
               connection.setDoInput(true);
               connection.setDoOutput(true);
               connection.connect();
               //Send request
               DataOutputStream dataStream = new DataOutputStream (connection.getOutputStream());
               File uploadFile = new File("../toSend/file.png");
               FileInputStream fileInputStream = new FileInputStream(uploadFile);
               try
               // create a buffer of maximum size
int bytesAvailable = fileInputStream.available();
int maxBufferSize = 1024;
int bufferSize = Math.min(bytesAvailable, maxBufferSize);
byte[] buffer = new byte[bufferSize];
// read file and write it into form...
int bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0)
dataStream.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
// closing CRLF
dataStream.writeBytes("\r\n");
          catch(Exception e)
          System.out.println("Exception: " + e.getMessage());
               //dataStream.writeBytes(urlParameters);
               dataStream.flush ();
               dataStream.close ();

Here is the client code... What I need is the server code... I want to save the file to hard disk, when a post is performed.And you want to use a servlet to do that? Then your google keywords are "file upload servlet". I recommend the links which recommend using Apache software in your servlet.
