This is a FAQ.

Just use java -Dlog4j.configuration=your/file/path.properties. See http://logging.apache.org/log4j/1.2/manual.html#defaultInit for details about this system property.

  • Property value should be a valid URL. The correct way is: `-Dlog4j.configuration=file:your/file/path.properties` – Nolequen Apr 04 '17 at 07:45

org.apache.log4j.LogManager.resetConfiguration( );
if ( System.getProperty( "log4j.config" ) != null ) {
    DOMConfigurator.configureAndWatch( System.getProperty( "log4j.config" ) );
}
else {
    DOMConfigurator.configure( Loader.getResource( "log4j.properties" ) );
}

Use this one time; you only have to specify the path to your log4j file via system paramaters: 

-Dlog4j.config=/path/to/your/log4j.properties
