send file via client - server model

[spasavvas]

Itry to send a file from client to server.
I do it, but when the server receive the file send an ack msg, then the client give error:
java.net.SocketException: socket closed
i don't know why.
my code is

client:
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", 9632);
System.out.println("i am client & connect");
inm = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
outm = new PrintWriter(clientSocket.getOutputStream(), true);
System.out.println("------1--------" +clientSocket.isClosed());
outm.println("msg 1: hi");
System.out.println("from server__ " +inm.readLine());
outm.println("msg 2: now i will send you a file");
System.out.println("from server__ " +inm.readLine());
sendFile();
System.out.println("-------2-------" +clientSocket.isClosed());
System.out.println("from server__ " +inm.readLine());
System.out.println("-------3------nothing-" );
}
catch(IOException e){
e.printStackTrace();
}
}
public void sendFile(){
try{
bis = new BufferedInputStream(new FileInputStream("encryptAtmMsg.txt"));
bos = new BufferedOutputStream(clientSocket.getOutputStream( ));
byteArray = new byte[8192];
while ((in = bis.read(byteArray)) != -1){
bos.write(byteArray,0,in);
}
bis.close();
bos.close();
}
catch(IOException e){
e.printStackTrace();
}
}
public static void main(String[] args){
new Client();
}
}

server:
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(9632);
System.out.println("i am server & listening...");
socket = serverSocket.accept();
System.out.println("a client connect");
System.out.println("------1--------" +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("------2--------" +socket.isClosed());
outm.println("ack 3: take the file");
}
catch (IOException e){
e.printStackTrace();
}
}

public void receiveFile(){
try{
byte[] receivedData = new byte[8192];
bis = new BufferedInputStream(socket.getInputStream());
bos = new BufferedOutputStream(new FileOutputStream("encryptAtmMsg22.txt"));
while ((in = bis.read(receivedData)) != -1){
bos.write(receivedData,0,in);
}
bos.close();
}
catch (IOException e){
e.printStackTrace();
}
}
public static void main(String[] args){
new Server();
}
}

any idea pls

In the client:
bis.close();
bos.close();

bos.close() closes the underlying stream, not just the BufferedOutputStream. Comment that line out, and things should work for you.

when i do it the client didn't send the data

thanks

Sorry, change it from bos.close() to bos.flush() and see if that takes care of it for you (you will eventually have to close bos though, or you'll slowly leak memory, but this will get you started to the solution).

Hello ! I have a problem ...Can anybody help me? plz?

I want to play an mp3 file and the code in eclipse is something like the following ... I see the interface but it can't be played...

import javax.swing.JButton;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JSplitPane;

public class AudioFilee extends JFrame {

public AudioFilee() {

setTitle("Music File");
setSize(300, 400);

JPanel jp1 = new JPanel();
JPanel jp2 = new JPanel();


JButton s= new JButton("STOP");
JButton p= new JButton("PLAY");
JLabel j1 = new JLabel("MusicFile");
String[] musicfiles={"workspace/eclipse/Audio/asdf.mp3","asd.mp3"};
JComboBox musiclist=new JComboBox(musicfiles);
musiclist.setSelectedIndex(1);


jp1.add(j1);
jp1.add(musiclist);

jp2.add(s);
jp2.add(p);



JSplitPane splitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT,
true, jp1, jp2);

splitPane.setOneTouchExpandable(true);
getContentPane().add(splitPane);

}
public static void main(String[] args) {

AudioFilee sp = new AudioFilee();
sp.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
sp.setVisible(true);

}
}

Do you have any suggestion? Thanks
