Hi,
I have a byte[] that is my message.
How can I sent it by TCP protocol?
What kind of output stream have I use?

Thanks
palmis

Look at java.net.URL for information on connecting to another computer
via TCP/IP. If you want to send the byte[] to a servlet or JSP, you
could use java.io.ObjectOutputStream.

Dear garyD,
I want to send byte[] to another computer (TCP client).
I have find some java commands but I don't know the kind of Output
stream that I have to use for sending.

Thanks
Palmis.

To send and receive byte data, use a plain or buffered OutputStream
and InputStream.

There is an overview of the various stream types here:

Class java.net.Socket has a getOutputStream() method. Therefore you can
just use that OutputStream without knowing what kind of OutputStream it
actually is:
Socket socket = new Socket(host, port);
OutputStream os = socket.getOutputStream();
byte message[] = ....;
os.write(message);

See http://mindprod.com/applets/fileio.html
tell it you want to write raw bytes to a socket.

Have a look at java.net.Socket.
