Hi,

 I have a problem with my application that is:

 Some times I have to send data to a server, and I do this using this
code:
  First I have to get the sockWriter:

 try {
            sock = getSocket();
            sockReader = sock.getInputStream();
            sockWriter = sock.getOutputStream();
            String recv = receiveSigleLineResponse();
    }catch (IOException e){
            throw new ConnectionException(e.getMessage());
}

ok, at this point everything works. The problem begins every time I
need to send the data, and here is the code:

      sockWriter.write(new String(mailData + LINE_FEED + "." +
LINE_FEED).getBytes());

this lines works well, but once my program reaches this line of code,
it "hangs" until this function
returns, this is expected, of course. But I want the user to see a
progress bar showing how much data has already been sent to the server.
And I can't do this, because send() is blocking until all data have
been sent.
 What I want is a way to keep checking how much data the function sent
so I can update the progress bar.

 I don't know if I was clear, but thanks in advance.

 Thanks!

Two things.
One, don't send all of the bytes in one chunk. Split it into different
chunks.
Two, print out how many chunks have been sent so far.
Possibly having an 1024 byte chunk, you would be able to display(chunks
+ "k bytes have been sent")
