Passing files through sockets...

Hi,
I want to pass some files, from one machine to another via socket system.
My questions is, how to read and pass the files?
Reading the file and storing it in an array of bytes, and then serializing this array?

There is another way to do that more clean?

Thx
MARC

Hello, you can write something like this:

//Sending
byte[] buf = new byte[1024];
int length = fileinputstream.read(buf);
while (length > 0){
socketoutputstream.write(buf,length);
length = fileinputstream.read(buf);
}

//Receiving
byte[] buf = new byte[1024];
int length = socketinputstream.read(buf);
while (length > 0){
fileoutputstream.write(buf,length);
length = socketinputstream.read(buf);
}

try this:
// sending a file:

FileInputStream in = new FileInputStream("myFile");
byte[] buffer = new byte[2048];
Socket s = new Socket("localhost", 12345);
OutputStream out = s.getOutputStream();
int r;
while ((r = in.read(buffer)) != -1)
out.write(buffer, 0, r);

out.flush();
out.close();

// receiving the file:

FileOutputStream out = new FileOutputStream("myFile");
byte[] buffer = new byte[2048];
Socket s = (new ServerSocket(12345)).accept;
InputStream in = s.getInputStream();
int r;
while ((r = in.read(buffer)) != -1)
out.write(buffer, 0, r);

out.flush();
out.close();
