My assignment is B&S and it has cookie to lock and unlock record.
So I don't need the client id benefit from RMI Connection Factory.
I still try to use RMI Connection Factory because there is other benefit from it like only register once.
However, I choose to return the same DvdDatabase instance to client because
I can control the synchronization of record locking.

But according to Andrew's book,
If two remote invocations share the same DvdDatabase instance,
This can't ensure thread safety.

Why?

Thanks

Lee
