The following connects a client and a server without using any sun.net
classes. To make it useful, you need some sort of protocol such as a
simple command/response one. If you are already using two pipes for
inter-app communication, the same protocol will work.
Server side:
ServerSocket socket = new ServerSocket(port_number, 10);
if (i >= 10) {
error("**Failed to create port\n");
return;
}
Socket connection = socket.accept();
DataInputStream in = new DataInputStream(
new BufferedInputStream(cmdSocket.getInputStream()));
DataOutputStream out = new DataOutputStream(
new BufferedOutputStream(cmdSocket.getOutputStream()));
Client side:
Socket socket = new Socket(host, port_number);
in = new DataInputStream(new
BufferedInputStream(socket.getInputStream()));
out = new DataOutputStream(new
BufferedOutputStream(socket.getOutputStream()));
