I have a Java client and a C++ server. How to send 1 byte to the
server?
This what I am doing in my Java client:

     byte b = 4;
     Socket s = new Socket(server, port);
     DataOutputStream out = new DataOutputStream(s.getOutputStream());
     System.out.print("Connection established on port " + port);
     out.writeByte(b);

This is how I am accepting this byte in C++ server:
char InputStream::read()//reads one byte at a time
{
  char byte;
  int size = 0;

  while (size != 1) {
       size = soc->recv(&byte,1);
  }
     return byte;
}

The server does read 1 byte, Howerver, when I try to print the byte
sent from the server, all I get is empty space.
I am assuming that the problem is in how I am sending this byte. Please
help.
