jdbc newbie question

Hi guys,

I've got a postgreSQL database setup and installed with jdbc, but I'm
having trouble getting WebObjects to make a connection to the
database.  I'm getting a "no driver detected" error message.  I've
tried to load up the driver using:

java -Djdbc.drivers=org.postgeresql.Drver example.ImageViewer

which doesn't seem to work. Any suggestions?  I'm running Mac OS
10.04, PG 7.1.2.


TIA

Russ
