When -Dlog4j.debug=true is set, Log4j prints its configuration progress to 
System.err.  With this, you should be able to see which config file is being 
picked up.

You can run your appender at a specified time by not placing log4j.properties 
in the classpath.  But then you'll have to manually configure it at some later 

Note that if you also place a log4j.jar with WEB-INF/lib and another Log4j 
config file in WEB-INF/classes of your webapp, you will get a separate logger 
repository from the server containing a different configuration.  If you 
remove your config file from WEB-INF/classes, you'll still have a separate 
logger repository from the server but use the same config as the server.
