logging - Configuring jetty's Stdout/Stderr to redirect to log4j -

i tried configure jetty log4j. create logfiles. however, capture/configure output log4j stdout , stderr.

is there way configure jetty-logging.xml uses slf4j , redirects stdout , stderr defined logger, can configure in log4j.properties?

i thinking of this:

<configure id="logging" class="org.eclipse.jetty.util.log.slf4jlog">    <!-- redirect stdout , stderr logger name 'stdoutstderrlogger' -->     <new id="serverlog" class="???">       <arg>         <new class="???">            <!-- ?????  -->           <get id="serverlogname" name="???"/>         </new>       </arg>     </new>      <get name="rootlogger">         <call name="info"><arg>redirect stdout , stderr logger name 'stdoutstderrlogger' <ref refid="serverlogname"/></arg></call>     </get>     <call class="java.lang.system" name="seterr"><arg><ref refid="serverlog"/></arg></call>     <call class="java.lang.system" name="setout"><arg><ref refid="serverlog"/></arg></call>  </configure>
