Constructor Detail

DriverDataSource

public DriverDataSource(Driver driver,
                        String connectionUrl,
                        String userName,
                        String password)

Creates a DriverDataSource wrapping a given Driver. If "driver" is null, DriverDataSource will consult DriverManager for a registered driver for the given URL. So when specifying null, a user must take care of registering the driver. "connectionUrl" on the other hand must NOT be null.
