How to Read from a client and send to another client through a server socket in Java

问题

I have been suffering a huge problem in my server to send an object received from a client to another client. This object is a ChatMessage. My server is able to send that message to the same client, but I can not think of a way to route this message to another client.

Please help Thank you very much in advance.

The server needs both client connections open at the same time and a way to know that a message received from client-1 should be routed to client-2. Your protocol needs to handle BOTH client-to-server and server-to-client requests.

There's any number of examples on the net for this. A quick google brought up this tutorial:

You need to maintain multiple connections, one for each client, and send the data to the appropriate clients when you receive it.
