JDBC and fetching the OID of an insert

Hi,

Does anyone of you know, how to get the OID of the just inserted Row after
stmt.executeUpdate("INSERT... ")? I hope this is possible at all!

If it's not, I would be willing to implement getGeneratedKeys() to return at
least the OID of an insert. Assuming that would be possible and exceptable?

(Btw. am I correct that the only way to get a value for a sequence via JDBC
is to "SELECT currval('...')" resp. "SELECT nextval('...')"?)


Best Regards,
Michael
