Server Client does not send file

I have a client and server that are communicating quite nicely and the connection is good, but I does not send the file using the methods that I wrote. I really dont know what I did wrong here at all. Well here is the servercode

Code :

---

import java.net.*;
import java.io.*;
 
class Server{
    BufferedInputStream bis;
    BufferedOutputStream bos;
    byte[] data;
    Socket socket;
    ServerSocket serverSocket;
    int in;
    BufferedReader inm = null;
    PrintWriter outm = null;
 
public Server()
{
    try{
        serverSocket = new ServerSocket(4444);
        System.out.println("Server setup and listening...");
        socket = serverSocket.accept();
        System.out.println("Client connect");
        System.out.println("Socket is closed = " +socket.isClosed());
        inm = new BufferedReader(new InputStreamReader(socket.getInputStream()));
        outm = new PrintWriter(socket.getOutputStream(), true);
        System.out.println("from client: " +inm.readLine());
        outm.println("ack 1: hi....");
        System.out.println("from client: " +inm.readLine());
        outm.println("ack 2: ok....");
        receiveFile();
        System.out.println("Socket closed = " +socket.isClosed());
        outm.println("ack 3: take the file");
        }catch (IOException e)
        {
            e.printStackTrace();
        }
    }
 
//make public to reverse fix
private void receiveFile(){
    try{
        byte[] receivedData = new byte[8192];
        bis = new BufferedInputStream(socket.getInputStream());
        bos = new BufferedOutputStream(new FileOutputStream("request.xml"));
        while ((in = bis.read(receivedData)) != -1){
        bos.write(receivedData,0,in);
        }
        bos.flush();
    bos.close();
    }catch (IOException e)
    {
        e.printStackTrace();
    }
    }
public static void main(String[] args)
{
        Server server = new Server();
}
}

and here is the client code:

Code :

---

import java.net.*;
import java.io.*;
class Client{
    Socket clientSocket;
    byte[] byteArray;
    BufferedInputStream bis;
    BufferedOutputStream bos;
    int in;
    BufferedReader inm = null;
    PrintWriter outm = null;
 
public Client()
{
    try{
        clientSocket = new Socket("localhost", 4444);
        System.out.println("Client is connect");
        inm = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
        outm = new PrintWriter(clientSocket.getOutputStream(), true);
        System.out.println("Socket Closed = " +clientSocket.isClosed());
        outm.println("msg 1: Client messageing open");
        System.out.println("from server__ " +inm.readLine());
        outm.println("msg 2: Sending file");
        System.out.println("from server__ " +inm.readLine());
        sendFile();
        System.out.println("Socket closed = " +clientSocket.isClosed());
        System.out.println("from server__ " +inm.readLine());
 
    }catch(IOException e)
    {
        e.printStackTrace();
    }
}
//make public to revers fix
private void sendFile(){
    try{
        bis = new BufferedInputStream(new FileInputStream("request.xml"));
        bos = new BufferedOutputStream(clientSocket.getOutputStream( ));
        byteArray = new byte[8192];
        while ((in = bis.read(byteArray)) != -1){
        bos.write(byteArray,0,in);
        }
        // bis.close();
         bos.flush();
        }catch(IOException e)
        {e.printStackTrace();}
}
public static void main(String[] args){
Client client = new Client();
 
}
}
