// Program to transfer files from one server to another in java and also display a progress bar on each file transfer

You can use "ServerSocket" for this.

Main logic is:

Socket socket = serverSocket.accept();
System.out.println("Accepted connection : " + socket);
File transferFile = new File ("Document.doc");
byte [] bytearray = new byte [(int)transferFile.length()];
FileInputStream fin = new FileInputStream(transferFile); 
BufferedInputStream bin = new BufferedInputStream(fin);
bin.read(bytearray,0,bytearray.length);
OutputStream os = socket.getOutputStream();
System.out.println("Sending Files...");
os.write(bytearray,0,bytearray.length);
os.flush(); socket.close();
System.out.println("File transfer complete");

I hope this would help you.
