Trouble reading 2 files on server

Question

I have the code written to upload a file to the server. I want to be able to upload 2 files to the server with the same socket connection. Any ideas how to do this? Also when i upload the file it doesn't always send the whole file. Any ideas why this is happening and how i can fix this? I'll post the code I have below.

           ServerSocket serverSocket = null;
          boolean listening = true;
          try {
                 serverSocket = new ServerSocket(12345);
             } catch (IOException e) {
                 System.err.println("Could not listen on port: 12345.");
                 System.exit(-1);
             while (listening)
                  new ServerThreads(serverSocket.accept()).start();
                 serverSocket.close();
