NX: Please Help! - Naming.rebind and Port

Using Max's code and info from some other posts I am trying to
start a user specified port (XXXX = any port) using:
java.rmi.registry.LocateRegistry.createRegistry(XXXX);
and then I make the call:
RecDatabaseImpl aRec = new RecDatabaseImpl();
Naming.rebind("RecMediator", aRec);
My question is how does the Naming.rebind("RecMediator",aRec) recognize
the port XXXX???
By simply calling java.rmi.registry.LocateRegistry.createRegistry(XXXX)?
I dont understand how the two calls automatically tie into eachother becuase
the Registry object returned by LocateRegistry.createRegistry(XXXX) is
never used. Instead the code simply moves on and calls
Naming.rebind("RecMediator", aRec);

Hi Bill
Max's code starts the RMI Registry on the "well known" port: 1099. The rebind is just using that well known port. It would not work if you used any other port.
This would be a good time for you to visit the Naming API - this will explain how you can specify the port number in the name that you use as a parameter to bind(), rebind(), lookup() ....
I suggest you look at that reference first, then come back with any questions after that.
By the way, the LocateRegistry.createRegistry() method returns a reference to the registry that is started, so you could call rebind() on that reference and then you would not need the port number either.
Regards, Andrew
