I don't know, but that's a JDBC issue. Have you tried simply casting the
long to an int? I'm using the same code as you and it works. The next
problem you're sure to encounter is an invalid OID value (0). This is
caused by trying to access large objects outside of a transaction. I assume
you aren't using transactions since I don't see a "conn.commit()" after the
executeUpdate() call.

Yes indeed. 7.1 is the latest stable release driver, and 7.2 is in development.
