You just have to setup the log configuration and classpathes correct, see below.

Whee must I put the log4j.jar : tomcat.5.5.12/share/lib ? Download Log4J (v1.2 or later) and place the log4j jar in $CATALINA_HOME/common/lib. Download Commons Logging and place the commons-logging.jar (not commons-logging-api.jar) in $CATALINA_HOME/common/lib with the log4j jar. To configure the server globally (not per webapp) Save log4j.properties into $CATALINA_HOME/common/classes Remove any log4j.jar or commons-logging.jar from you webapp to test it. There are two excellent documentations about the configuration: http://tomcat.apache.org/tomcat-5.5-doc/logging.html http://tomcat.apache.org/faq/logging.html There is an other document describing the classloading: http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html Regards Boris --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
