Java简单RMI聊天应用程序

Question

I am trying to make a very simple chat program using RMI ( no GUI's ) but i am struggling for ideas. How do i register clients when they connect to the server? When i use

RemoteServer.getClientHost()

all this does is show the ip address (and they are the same for all clients that connect from the same computer (from multiple command windows). What i am trying to implement is this: when a client logs on he is shown a switch-case menu and ift they press

1. they get a list of connected clients.

2. sendMessage(client, String)

But i do not know how to identify individual clients?

And when i do, how do i show a string only on that client's window ?

Thanks,

Research: (i have looked at ideas on the web but a lot of them are more advanced than i want. This is a simple application and i do not want to complicate it / copy code i dont understand). There are previous questions on SO but with 0/1 answers (not very popular topic!) or not helpful!

Answer 1

Looks like i found what i was looking for:

RMI Callback

Basically making every client a server, so the server can respond as well as receive messages.

I have been directed to a resource that might help:
