Method Detail

getPooledConnection

public javax.sql.PooledConnection getPooledConnection()
                                               throws SQLException

public javax.sql.PooledConnection getPooledConnection(String user,
                                                      String password)
                                               throws SQLException

getLogWriter

public PrintWriter getLogWriter()
                         throws SQLException
Get the log writer for this data source. The log writer is a character output stream to which all logging and tracing messages for this data source object instance 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 data source object is created the log writer is initially null, in other words, logging is disabled.
Returns:
the log writer for this data source, null if disabled
Throws:
SQLException - if a database-access error occurs.
Since:
JDBC 2 Standard Extension, proposed for future release, not yet supported

setLogWriter

public void setLogWriter(PrintWriter out)
                  throws SQLException
Set the log writer for this data source.

The log writer is a character output stream to which all logging and tracing messages for this data source object instance 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 data source object is created the log writer is initially null, in other words, logging is disabled.

Parameters:
out - the new log writer; to disable, set to null
Throws:
SQLException - if a database-access error occurs.

setLoginTimeout

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 data source object is created the login timeout is initially zero.
Parameters:
seconds - the data source login time limit
Throws:
SQLException - if a database access error occurs.

Gets the maximum time in seconds that this data source can wait while attempting to connect to a database. A value of zero means that the timeout is the default system timeout if there is one; otherwise it means that there is no timeout. When a data source object is created the login timeout is initially zero.
