You actually want to use DOMConfigurator when using an XML file for configuring log4j. PropertyConfigurator is only for reading properties files.
DOMConfigurator.configureAndWatch() is a handy method, because you can set an interval to re-check the configuration file, meaning if you want to change log levels, you won't have to restart your container.
