What us the best way to auto-update a Java Application that is installed on
a number of clients, from a network drive or an AS/400?

Is is best to write my own Jar installer, similar to the
AS400ToolboxInstaller?
Can this be done by writting my own class loader, and if so how would I go
about it?

Or is there something out there to do this for me, either something in the
Java Platform I haven't found, or a utility / bean somewhere out there
that's done this for me?

Thanks,
Chris.
