Socket Question: Client not receiving the server messages...

Question

I have a client and server where in the client sends the server a file name to look for. The server looks for that file and checks for its existence and reads the file line by line displays it and then sends it to client. The client should recieve the contents send by the server and display it line by line. Here is what I have done
Server
import java.io.*;
import java.net.*;
import java.awt.*;
import javax.swing.*;
public class Server extends JFrame
     public static void main( String args[] )
//Pass the port no as an argument
Server s = new Server(Integer.parseInt(args[0]));
s.runServer();
     private ServerSocket ss;
     private Socket Connection;
     private BufferedReader input;
     private BufferedWriter output;
     private PrintWriter poutput;
     private int port;
     private int bufLength;
     private JTextArea display;
     public Server(int port)
          super( "Socket Server" );
          display = new JTextArea();
          getContentPane().add( display, BorderLayout.CENTER );
          setSize( 400, 300 );
          setVisible( true );
// Construct of a socket
          try
               ss = new ServerSocket(port);
          catch( SocketException se )
               se.printStackTrace();
               System.exit( 1 );
          catch( IOException io )
               io.printStackTrace();
     public void runServer()
          String fileName = null;
          try
               Connection = ss.accept();
               input = new BufferedReader(new InputStreamReader(Connection.getInputStream()));
               OutputStreamWriter out = new OutputStreamWriter(Connection.getOutputStream());
               boolean done = false;
               while(!done)
                    String lline = input.readLine();
                    if (lline != null)
                         done = true;
                         display.append( "\nThe server has read the file name:" + lline);
                         fileName = lline.trim();
               input.close();
               File fileLoc = new File(fileName);
               if (fileLoc.exists())
                    input = new BufferedReader(new FileReader(fileLoc));
                    boolean eof = false;
                    while (!eof)
                         String line = input.readLine();
                         if (line == null)
                              eof = true;
                         else
                              display.append( "\nThe server has read the line:" + line);
                              out.write(line);
                         Connection.close();
               else
                    String message = "The file specified does not exist on this server. Recheck your request";
                    poutput.println(message);
               out.flush();
          catch (Exception e)
               System.out.println(e);

For starters, change while(eof) to while(!eof)
