title: Wicket logging configuration
body: <p>I have a Wicket 1.4.17 app in a standalone app in embedded Jetty 6.1.26.
  My application uses <code>log4j</code> over <code>slf4j</code>.</p>
  
  <p>My app consists of two JARs, core and web modules.
  I have same <code>log4j.properties</code> in both - by which I tried to exclude a possibility of some classloader not picking up .properties from non-web JAR.</p>
  
  <p>For my classes, the log4j configuration works - e.g. the messages are on a single line.
  However, for Wicket, it seems to use some default.</p>
  
  <p>How can I unify logging config?</p>
  
  <p>BTW Jetty uses <code>java.util.logging</code>.</p>
  
  <p>Thanks,
  Ondra</p>
