Using WO with multiple users.

[IDfusion <solutions@id-fusion.com>]

I want to create an application where multiple users can access, view
and modify the database all at once. With other applications you must
use some sort of locking mechanism to ensure the state of the database
is not comprimised. I want to start tackling this with WebObjects and
Oracle. Would anyone be able to give me an idea as to where to start?
What are my choices for locking mechanisms (optimistic, pessimistic,
etc...) I am using Java with WO and any examples, which I can not find,
would be very helpfull. I've never developped a multiple user
application with a web based tool and am unsure as the differences from
that to a desktop (Networked) application.

Thank Robert

Happy New Year.
