The following page has been changed by plinius: http://wiki.apache.org/tomcat/FAQ/Logging ------------------------------------------------------------------------------ [[Anchor(Q4)]]'''How do I configure commons-logging for use with Tomcat?''' - You need to specify a commons-logging configuration file and, if you wish, a logging implementation that supports commons-logging. JDK 1.4 (and later) java.util.Logging and Log4j are the two most commonly used logging toolkits for Tomcat. If you supply an external logging toolkit such as Log4J, it needs to be located in the $CATALINA_HOME/common/lib directory (for Tomcat 5.0 and earlier) or added to the bootstrap classpath by using the scripts in $CATALINA_HOME/bin (this is required for Tomcat 5.5 and later, which uses commons-logging while bootstrapping, and optional for Tomcat 5.0 and earlier). + You need to specify a commons-logging configuration file and, if you wish, a logging implementation that supports commons-logging. JDK 1.4 (and later) java.util.Logging and Log4j are the two most commonly used logging toolkits for Tomcat. If you supply an external logging toolkit such as Log4J, it needs to be located in the $CATALINA_HOME/common/lib directory (for Tomcat 5.0 and earlier). Tomcat 5.5 and later uses commons-logging while bootstrapping so some people suggest adding Log4j to the bootstrap classpath by using the scripts in $CATALINA_HOME/bin (see [http://markmail.org/message/3sgxfol3njcfutsm Need for it to be in bootstrap classpath?]). A better approch apparently working is: + 1. Put jog4j.jar in the $CATALINA_HOME/common/lib directory + 2. Put the ''full'' commons-logging.jar in the $CATALINA_HOME/common/lib directory, even if you see the ''reduced'' API version there, named commons-logging-api.jar + + Through some classloading voodoo during bootstrapping, if you have the full commons-logging.jar file in your common/lib directory, it replaces the classes from the commons-logging-api.jar file and will reinitialize the logging system and attempt to locate log4j or whatever other logging system you may be using.
