title: log4j warning issue - apache commons
body: <p>I'm using apache commons library and log4j.
  I have an xml configuration file and a log4j.properties files. I want to specify my log4j properties path inside my xml configuration file.
  To load my settings i do: </p>
  
  <pre><code>//Loading my xml file
  this.config = new XMLConfiguration(this.xmlFileName);  
  </code></pre>
  
  <p>At this moment the following warnings are raised:</p>
  
  <pre><code>log4j:WARN No appenders could be found for logger (org.apache.commons.configuration.ConfigurationUtils).
  log4j:WARN Please initialize the log4j system properly.
  log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
  </code></pre>
  
  <p>However i haven't yet called any log4j object. Once i have read the xml file i can successfully work with my log4j instance.
  Is there any way to remove those warnings?</p>
