Hi Laura, if I am correct the Channel you are referring to is in the java.nio package which is not allowed for the
SCJD. And the instructions clearly stated "assume only one program assess the database file at any moment".
All I have said in my choices.txt in my assumptions is something on the line:
* The stand-alone version and networked version will not run at the same time on the same computer
The only lock issue you do need to worry is the record locking (eg those lock, unlock, isLocked methods). What you are doing with Channel is more of file locking which can be assumed.
