Retrieves the log writer for this DataSource
object.
The log writer is a character output stream to which all logging and
tracing messages for this data source will be printed. This includes
messages printed by the methods of this object, messages printed by
methods of other objects manufactured by this object, and so on. Messages
printed to a data source specific log writer are not printed to the log
writer associated with the java.sql.Drivermanager
class.
When a DataSource
object is created, the log writer is
initially null; in other words, the default is for logging to be
disabled.

public void setLoginTimeout(int seconds) throws SQLException
Sets the maximum time in seconds that this data source will wait while
attempting to connect to a database. A value of zero specifies that the
timeout is the default system timeout if there is one; otherwise, it
specifies that there is no timeout. When a DataSource
object
is created, the login timeout is initially zero.
