Getting the count of rows in a Java resultset

Does anyone know a better way of getting the number of rows in a Java resultset returned from a MySQL database? The resultset returned is not going to be the total number of rows read from the database so I don't think I can use SQL's COUNT aggregate function.

public static int getResultSetRowCount(ResultSet resultSet) {
    int size = 0;
    try {
        resultSet.last();
        size = resultSet.getRow();
        resultSet.beforeFirst();
    }
    catch(Exception ex) {
        return 0;
    }
    return size;
}
