Hmmm... I am assuming that once your web app is up then you are not going to make any change in the web.xml....

Now what you can do is a create a servlet which loads on the startup and initialize a singleton class. You can use the following setting in your web.xml.

  
    
    XMLStartUp
    XMLStartUp
    com.test.servlets.XMLStartUp
    
      log4j-init-file
      WEB-INF/classes/log4j.properties
    
    0
  

In tomcat if you set load-on-startup value 0, then it means that while loading it has got the highest priority. now in the servlets init method read all the init-parameters like this and set it in your singleton class.

String dummy= getInitParameter("log4j-init-file");
