how to send files through sockets

[gabriel]

I'm developing a program and I need to send files through sockets
I'm using BufferInputStream,DataInputStream.
I choose some file from server and then send it to the client.
The client receives it but it doesn't open!
I send you my code


In server I do something like that:

Code:

public class Server
{
static final int Port=5000;
public int nClients=0;
private String file="./files/3.jpg";
/** Creates a new instance of server*/
public Server() 
{
try
{
ServerSocket serverSock=new ServerSocket(Port);
System.out.println( Port);
while(true)
{ 
serverSock.accept(); 
Socket cliente=serverSock.accept();
nClients++;
System.out.println(nClients);
SClient(client,nClients);


SocketThread thread=new SocketThread
(client,file,nClients-1);
hilo.start();
}
}
catch(Exception ex)
{
System.out.println(ex);
}
}

In the client I do that:

Code:

DataInputStream en = new DataInputStream
(skClient.getInputStream());
byte buffer[] = new byte[breaden];
//breaden=en.read(buffer);
File rec=new File("./rec/1.jpg");
rec.setReadable(true);
rec.setWritable(true);
//FileOutputStream f=new FileOutputStream(rec);
FileOutputStream f=new FileOutputStream
("./rec/1.jpg");
f.write(buffer);

skClient.close();

Anyone know where I can access a complete tutorial on how to send files through java sockets? If so, please tell me where, I'd be glad to receive any references. Thanks in advance!!!!

Gabriel, try to review this and see where you're going astray. This is something I plan to implement in my custom chat client, when I someday get to it, due to time constraints.

Best of luck!

EDIT: See these tutorials found here in our very own community, at the end - which makes note of using ObjectOutputStream and ObjectInputStream.
