Answer 1

A NotBoundException is thrown if an attempt is made to lookup or unbind in the registry a name that has no associated binding.

What is your server code look like? This exception you are having most likely caused by server not set up properly.

I think in your server code you are bind with name ChatServer

 Naming.rebind("ChatServer", new Server());

But in your client code you are using ServerInterface name

String address = "rmi://localhost/ServerInterface";
