if I remember correctly, oracle requires the name of its database service in the connection parameters (aka schema).
Try something like: jdbc:oracle:thin:someuser@//myhost:1521/myservicename If you aren't doing a thin connection, I'm sure the same principle still applies. Oracle likes the schema on the URL (aka service name?) It's been awhile, so I'm not completely sure. Hope you get it connected.
