Connector/J 2.0.14 is _very_ old, it predates JDK-1.4 by quite a bit, so
that explains the fact the method isn't there at all :)
MySQL versions prior to 4.1 don't have prepared statements at all, they
are emulated in the JDBC driver. Therefore the driver can't implement
this method for MySQL < 4.1.
MySQL 4.1 has 'true' prepared statements, but doesn't currently return
parameter metadata for PreparedStatements, but this is planned sometime
during the 4.1 timeframe.
