title: log4j error message in repast simphony - batch run
body: <p>when starting my Repast Simphony Model in Batch run I get this error message:</p>
  
  <pre><code>log4j:WARN No appenders could be found for logger (RLFA.society3.run.1.1).
  log4j:WARN Please initialize the log4j system properly.
  </code></pre>
  
  <p>The answer here concerning log4j <a href="http://repast.sourceforge.net/docs/tutorial/SIM/Frequently%20Asked%20Questions.html#FrequentlyAskedQuestions-log4j" rel="nofollow">http://repast.sourceforge.net/docs/tutorial/SIM/Frequently%20Asked%20Questions.html#FrequentlyAskedQuestions-log4j</a> doesn't help at all, since I got the problem ONLY when starting batch run. When starting the model normally everything is fine. And I also couldn't adapt any of the other log4j problems/answers here in stackoverflow, since that problem within Repast Simphony seems rather specific.</p>
  
  <p>Anyone ran into this problem before and solved it? Or Maybe an idea, what this RLFA is?</p>
  
  <p>Note: the error occurs when the model is fully initialized, during the first step.</p>
  
  <p>Thanks for every help,</p>
  
  <p>Andy</p>

  <p>edit: in velocity.log I found this loggings, where it says that a VM_global_library.vm is missing - but does this help further?</p>
