I believe somebody else meets this too, but I couldn't find related post.
To start rmi server programatically, I use LocateRegistry.createRegistry(portNum);
my code:
LocateRegistry.createRegistry(1099);
Hello h = new Hello("Steve");
Naming.rebind("TEST",h);
Everything works successfully for 1099(including client calling the method), however, if the port is not 1099, let's say 1098, the following exception occures at Naming.rebind.
I am using java version 1.4.2_01. Thank you for the advice!!

YungSheng,
The code you show creates a new registry but uses the default registry, not the new one.
After creating the registry, you have to get a reference to it and then use it to perform the binding as in the following example:

The createRegistry() method does have a return value, for precisely this purpose:

Yes, it works, thank you all.
In fact, we were taught to use network socket to write project in school. That may be quite different from you guys. Well I have to say RMI is more straightforward though.
Yap, if you ever implement the "network whiteboard" project, we may go to the same school.
