Don't confuse "not understanding" with "not sufficient". The instructions d=
o lead to a correct configuration. However, here it is more explicitly.

Per-webapp logging
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

1. Add log4j's jar to both your webapp's WEB-INF/lib folders
2. Add log4j.properties to both your webapp's WEB-INF/classes folders. *Min=
imally*, add

log4j.rootCategory=3Ddebug, R
log4j.appender.R=3Dorg.apache.log4j.RollingFileAppender
log4j.appender.R.File=3Dc:/jakarta-tomcat/logs/webapp-name.log
log4j.appender.R.MaxFileSize=3D1500KB
log4j.appender.R.MaxBackupIndex=3D1
log4j.appender.R.layout=3Dorg.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=3D%d - %5p (%C:%L) - %m%n

to those log4j.properties files changing the File path appropriately.

Ideally you will pick up the log4j manual and create appenders that map to =
packages.

Tomcat logging with log4j
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

I've found the best way is

1. Add log4j jar to common/lib, add commons-logging.jar to common/lib
2. Add log4j.properties to common/classes with content

log4j.rootCategory=3Derror, R
log4j.appender.R=3Dorg.apache.log4j.RollingFileAppender
log4j.appender.R.File=3Dc:/jakarta-tomcat/logs/tomcat.log
log4j.appender.R.MaxFileSize=3D1500KB
log4j.appender.R.MaxBackupIndex=3D1
log4j.appender.R.layout=3Dorg.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=3D%d - %5p (%C:%L) - %m%n

log4j.logger.org.apache.commons.modeler=3DINFO, R
log4j.logger.org.apache.tomcat.util.digester=3DERROR, R
log4j.logger.org.apache.catalina.loader=3DINFO, R
log4j.logger.org.apache.catalina.session=3DINFO, R
log4j.logger.org.apache.catalina=3DDEBUG, R
log4j.logger.org.apache.commons.digester=3DINFO, R
log4j.logger.org.apache.commons.beanutils=3DINFO, R
log4j.logger.org.apache.jasper=3DINFO, R
log4j.additivity.org.apache.catalina=3Dfalse

Tomcat logging per-webapp
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Add to your webapp's log4j.properties files

log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost][=
/webappname]=3DDEBUG, R=20
