macaddr data type and prepared statements

Hi All,

I'm trying to bulk load some MAC addresses using a prepared statement.
But I keep on getting an error about incorrect datatype (complains that
I'm trying to insert "character varying").  Bellow is an example of the
code that I'm using:

  try {

            Class.forName("org.postgresql.Driver");
            conn = DriverManager.getConnection(jdbc_url, jdbc_user,
jdbc_pass);

            PreparedStatement stmt = conn.prepareStatement("insert into
log (date, time, mac, network) values (?,?,?,?)");

            while (inputLineIterator.hasNext()) {
                String[] line = inputLineIterator.next();
                if (line == null) {
                    continue;
                }
            stmt.setDate(1, new java.sql.Date(
dfmt.parse(line[0]).getTime()) );
            stmt.setDate(2, new java.sql.Date(
tfmt.parse(line[1]).getTime()) );
            stmt.setString(3, line[2]);
            stmt.setString(4, line[3]);
            stmt.execute();
            }

            stmt.close();
}

Any recommendations?

Cheers

Steve
