top]Why can't log4j find my properties file in a J2EE or WAR application?

Apache log4j 1.2 - Frequently Asked Technical Questions
The short answer: the log4j classes and the properties file are not within the scope of the same classloader. The long answer (and what to do about it): J2EE or Servlet containers utilize Java's class loading system. Sun changed the way classloading works with the release of Java 2. In Java 2, classloaders are arranged in a hierarchial parent-child relationship. When a child classloader needs to find a class or a resource, it first delegates the request to the parent.

Because the configureAndWatch launches a separate wathdog thread, and because there is no way to stop this thread in log4j 1.2, the configureAndWatch method is unsafe for use in J2EE envrironments where applications are recycled.
