title: Initializing Log4j within Web Context(tomcat)?
body: <p>I checked log4j setup in my tomcat environment. Although there is no log4j-web.jar file in my webapp or in "common libs" folder, log4j is initialized properly. I only added log4j.properties in my classpath. And that's it, log4j is working.</p>
  
  <p>I am using spring mvc, sl4j-api.jar and sl4j-jcl.jar are in my classpath.</p>
  
  <p>My question is : How does log4j work properly and pickup the configuration?</p>
