  • Two clients?... you need someone that connects and someone that accept connection... 2 that like to connect with none accepting seems difficult... maybe include some server behavior in the client?, or the server stores the messages from the different clients and send it to them... – Petter Friberg Nov 19 '15 at 00:16

  • 2 clients that connect to 1 server? So server needs to relay all messages from all clients to all the other clients. Question is, how did you implement your server? Separate read & write threads per client? Or nonblocking even? Do you have some sort of message queue to enqueue messages to clients? Or in an event based system a global message bus? – zapl Nov 19 '15 at 00:21

You cannot connect a client socket to a client socket - however, you can use one of the following models:

  • One 'client' uses a ServerSocket, while another client uses a Socket, and connects the the ServerSocket
  • Someone (can be one of the clients) runs a server application which all clients connect to. The server relays messages in between the clients
