Thanks a lot. 1.So the constructor with parameter is not used at all? 2. Then that requires I call DOMConfigurator.configureAndWatch(..) in the code, not for using -D option 3. Well, the timestamp I need is far before the logging happens. I need to do the process first, the process maybe takes long, and then log the process result, where the time is the process time.
