The server socket is written in c++ and is running out there, it keeps listening to a socket on a specific port, once it receives something from the listened socket, it does some calculations and returns the results to the same listened socket(or possibly another one).
Now come back to my java client socket, it sends a string to the socket which it is connected to, and then it may need to do something else, once there is something returned from the server in the socket, the client should be informed and pick up the corresponding result for the string it just sent. For this problem, I need an asynchronous callback mechanism in my client side, all I have is the server's IP and the port number the socket will be connected. I've read a couple of posts and articles in the web, but seems did not resolve my problem, can any one help out? any help is greatly appreciated.
