Well, since I already had a simple JRuby app wrapped up with Warbler,
using jdbc to talk to PostgreSQL and deployed to my V2.1 DAS, I checked
this out.
It works against a standalone instance fine. All I had to do was
retarget the JDBC resource to my standalone instance and enable it
(don't ask me why it's not enabled by default, but it isn't), then
retarget the WAR file to the standalone instance, and voila, perfecto.
I'm not sure what the caused of your exception below. It does generally
work if configured correctly.
Good luck.
