Placing the jars in the common/lib directory makes them available for all web apps and catalina itself. Placing log4j properties in the common/classes lib defines log4j behavior for all web apps (cross context). Placing log4j properties in web-inf/classes overrides cross context log4j properties for a specific web app. What is the purpose of the commons-logging.properties file ? There is no requirement for this file according to the 5.5 doc. hope this helps. - andy pc leung <[EMAIL PROTECTED]> wrote: http://tomcat.apache.org/tomcat-5.5-doc/logging.html The above page shows that logging-log4j.jar and commong-logging.jar needs to put in $CATALINA_HOME/common/lib. If I have two files of jar already in my struts webapp lib, Why do I still need to place them in $CATALINA_HOME/common/lib? In addition, the tomcat doc web page shows the log4j.properties only, is the common-logging.properties not necessary? Thanks
