When you use a log4j.properties file instead of log4j.xml you can use http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PropertyConfigurator.html#configure(java.util.Properties)
1) load the log4j.properties file in a Properties object 2) add all custom properties to the Properties object 3) call PropertyConfigurator.configure(props) I have no idea if something similar can be done with the DOMConfigurator. You could search the ml archive, this question has come up more than once.
