file transfer via socket

[spasavvas]

Hi
I am trying to create a server – client model where client send a file and when server receive the file send back an ack msg.
My code is:
[PHP]
import java.net.*;
import java.io.*;

class Client{
public static void main (String[] args){

DataInputStream input;

BufferedInputSt ream bis;
BufferedOutputS tream bos;
int in;
byte[] byteArray;

try{
Socket client = new Socket("127.0.0 .1", 8585);

input = new DataInputStream (client.getInpu tStream() );

System.out.prin tln("Server message: " +input.readUTF( ) );

bis = new BufferedInputSt ream(new FileInputStream ("encryptAtmMsg .txt"));
bos = new BufferedOutputS tream(client.ge tOutputStream() );
byteArray = new byte[8192];
while ((in = bis.read(byteAr ray)) != -1){
bos.write(byteA rray,0,in);
}
bis.close();
bos.close();

System.out.prin tln("Server message: " +input.readUTF( ) );
}
catch ( Exception e ) {
System.err.prin tln(e);
}
}

}
[/PHP]
and
[PHP]
import java.net.*;
import java.io.*;

class Server{
public static void main (String[] args){

ServerSocket server;
Socket connection;

DataOutputStrea m output;

BufferedInputSt ream bis;
BufferedOutputS tream bos;

byte[] receivedData;
int in;
try{
server = new ServerSocket( 8585 );
while ( true ) {
connection = server.accept() ;

output = new DataOutputStrea m (connection.get OutputStream() );

output.writeUTF ( " ack 1" );

receivedData = new byte[1024];
bis = new BufferedInputSt ream(connection .getInputStream ());
bos = new BufferedOutputS tream(new FileOutputStrea m("sss.txt")) ;
while ((in = bis.read(receiv edData)) != -1){
bos.write(recei vedData,0,in);
}
bos.close();
output.writeUTF ( " ack 2" );
}
}
catch (IOException e ) {
System.err.prin tln(e);
}
}
}
[/PHP]

On which side? The client or the server?

Client give this error

Try flushing the buffered streams before you close anything. The rest of the logic
in your code seems ok.

kind regards,
