Why do I get an exception for an unexpected hostname and/or port number when I call Naming.lookup?
The hostname and port number you see in the exception trace represent the address on which the looked-up server believes it is listening. While the RMI server can theoretically be on any host, it is usually the same host as that on which the registry is running, and on a different port. Even if the server is mistaken about its hostname or IP address (or has a hostname that simply isn’t resolvable by clients), it will still export all of its objects using that mistaken hostname, but you will see an exception every time you try to receive one of those objects.
