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.

- if a database access error occursvoid 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.
