Is that possible at all? Can a librray change the way my logs are shown? How can I investigate this, since I am a bit

For the format of this properties file , you can refer to your JRE_HOME/lib/logging.properties (which is the default configuration file used by JUL) However, JUL

Or will the standard util.logging facility do the job as well? What do you think? 回答1: I'd say you're probably fine with util
