Look at Tomcat's class loading hierarchy. Classes loaded from Tomcat's lib directory are shared at runtime by all webapps (and Tomcat, for that matter), whereas classes coming from a webapp's WEB-INF/lib or WEB-INF/classes are local to that webapp. If the classes from Tomcat's lib directory have any static fields or singleton objects, only one copy of those fields and objects exist for all the webapps. I haven't looked inside log4j to see just what information in maintains in static fields or singletons, but keeping the log4j.jar with each webapp insures you won't get any unwarranted interaction in your webapps' logging. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
