After adding log4j to my application I get the following output every time I execute my application:
log4j:WARN No appenders could be found for logger (slideselector.facedata.FaceDataParser). log4j:WARN Please initialize the log4j system properly.
It seems this means a configuration file is missing. Where should this config file be located and what is a good start content?
I'm using plain java for developing a desktop application. So no webserver etc...
