Output destinations are handled by Appenders, not Loggers. In particualr,
file destinations are handled by FileAppender and its subslasses.
Programtically, you can do something like:
Logger logger = ...;
logger.removeAllAppenders();
FileAppender appender = new FileAppender();
appender.setLayout( new SimpleLayout() );
appender.setFile( "/usr/home/peter/logs/myLog.log" );
appender.activateOptions(); // This "initializes the appender, opening the
File, etc
logger.addAppender( appender );
