check out : http://wiki.apache.org/logging-log4j/Log4jXmlFormat

a log4j.xml like the following on the classpath will do it (from link above) :

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

    <layout class="org.apache.log4j.PatternLayout"> 
      <!-- Pattern to output the caller's file name and line number -->
      <param name="ConversionPattern" value="%5p [%t] (%F:%L) - %m%n"/> 
    </layout> 
  </appender> 
  <appender name="R" class="org.apache.log4j.RollingFileAppender"> 
    <param name="file" value="example.log"/>
    <param name="MaxFileSize" value="100KB"/>
    <!-- Keep one backup file -->
    <param name="MaxBackupIndex" value="1"/>
    <layout class="org.apache.log4j.PatternLayout">

    </layout> 
  </appender>
