Non-Networked Mode
The program must be able to work in a non-networked mode. In this mode, the database and GUI must run in the same VM and must perform no networking, must not use loopback networking, and must not involve the serialization of any objects when communicating between the GUI and database elements.
The operating mode is selected using the single command line argument that is permitted. Architecturally, this mode must use the database and GUI from the networked form, but must not use the network server code at all.

What is loopback networking?

Hi Peter,

What is loopback networking?

Loopback networking means that you try to connect a remote machine, where the machine in fact is the current machine you are using.
i.e. You try to connect to (IP form) or localhost (naming form).

Hi, Nick, Thanks.
Hope you get good result for SCJD.
I am still not very clear about loopback networking. When RmiImpl's object is not created, it is impossible for loopback net working to work, right?
I agree. Here's the link:
