Hi, You can set the log4j.defaultInitOverride system property (to any value other than false), and when so configured any log4j.properties or log4j.xml files on the classpath will be ignored.
However, it might simply be something else doing programmatic configuration before your code does it. It's not necessarily the default init process that's causing this.
