Ahh. Didn't realize there were two. That should work, though I still
prefer specifying the required holdability because that's what defines
whether or not you're able to use the (otherwise superior) cursor method.

Okay, I understand now. The confusion is, you wrote this:
Statement st = connection.createStatement(
ResultSet.CLOSE_CURSORS_AT_COMMIT,
ResultSet.CONCUR_READ_ONLY);
but evil gnomes changed the bits in my copy of the email to what I
expected, so I didn't notice a difference. ;) I meant this:
Statement st = connection.createStatement(
ResultSet.TYPE_FORWARD_ONLY,
ResultSet.CONCUR_READ_ONLY,
ResultSet.CLOSE_CURSORS_AT_COMMIT);
Type, concurrency, and holdability are all orthogonal parameters to
createStatement and prepareStatement.
Thanks,
Scott
