Hi,
I am also new for SCJD and recently downloaded the assignment. Just overall idea about SCJD:
1. You need to pay for the assignment $250 (US doller)
2. After a week or something you can download the assignment.
3. After completion of the assignment you will submit it and then have to take exam by paying another 150$.
4. After one month you will get result of both.
The assignment what I got is, there is already a working system which will be having all the classes and method. You need to understand the existing system and need to implement the same as client-server system either by using RMI or Network sockets. Its your choice.
Basically you need to be good in network, threads and GUI.
