Im fairly new to this socket world, so googled and came across a simple client server mechanism. Here is the link. So, the server waits for the client to connect to it. Now, I have a query. How can I modify the code so that it would help me simulate chating with some other person?. Cant we achieve the same without using the Server [ Server Socket ]?.
The way most chat applications work is that there's a server between the two clients. When you chat with your friends on Yahoo or Skype or Google chat, you each establish a connection to the server, and it relays the messages between you. Note that the server is a server in two different capacities:
1) At the socket level, it is opening the ServerSocket (or other API equivalent) and your chat clients are creating socket connections to that server socket.
2) At the application level, it serves as the relay host that A) has a public IP address and B) knows about accounts and who's online.
It is possible to create a peer-to-peer chat client that doesn't need a server in the sense of #2 above, but for the TCP connection, one end still has to open the ServerSocket as in #1 above. Also note that this approach only works if the server has a public IP address (or receives port forwarding form one) or if both client and server are on the same LAN.
