title: Log4j logging from a Neo4j server extension
body: <p>My unmanaged server extension uses slf4j-log4j logging. When log4j.properties is bundled with the extension, logging works fine. 
  When it's not bundled but instead placed in Neo4j's conf directory, I assumed </p>
  
  <pre><code>wrapper.java.additional=-Dlog4j.configuration=file:conf/log4j.properties
  </code></pre>
  
  <p>from <code>neo4j-wrapper.conf</code> would ensure that it's picked up. 
  However, I don't see the log file being created or the specified log level being used.
  The config file must be correct because it works as designed when bundled with the extension.
  Adding <code>-Dlog4j.debug</code> as suggested in other posts adds no further information.</p>
  
  <p>Is there something I've missed? I'm using Neo4j 2.1.3 on Mac OS X</p>
