Well, this is a blast from the past, I'm not actively
developing db2db anymore.

As for the problem, I see you're driver is a dll. Off the
top of my head, when you register the driver with db2db I
think you can use the 'Load driver from Classpath' checkbox.
Did you do that? Apart from that, I'd have to look into it.

You could use the Oracle thin drivers! These work ok as that
is what I use, and they are very good.

Post back if you can't get it working, and I'll help.
