You also need to copy commons-logging.jar and log4j-1.2.9.jar to $CATALINA_HOME/common/lib.

You also need to copy commons-logging.jar and log4j-1.2.9.jar to $CATALINA_HOME/common/lib. Note,

Note: If you want Tomcat logging to stdout as well, then your $CATALINA_HOME/common/classes/log4j.properties file should look like this:

For the official Tomcat 5.5 docs on logging see here [Tomcat 5.5 Logging|http://jakarta.apache.org/tomcat/tomcat-5.5-doc/logging.html]

If you cannot get the above instructions to work, then should remove the files you placed within the tomcat
