Subject Re: rotating catalina.out using log4j
Date Tue, 12 Feb 2008 20:06:20 GMT
David,
Thank you very much for your help with log4j 

>>> David Delbecq <delbd+jakarta@oma.be> 2/12/2008 2:53:40 AM >>>
catalina.out is just the sink for System.out and System.err, it's not 
managed by logging facilities. It's not even seen by jvm, as the 
redirection is done in the startup script (using the shell '>' 
redirector). If you configure a log4j logger for tomcat that uses an 
other file (see below our simple config) and teach all your webapps to

not use stdout and stderr, you shouldn't see anymore things appear in 
catalina.out. If you still need rolling of file during startup, you
will 
need to ask external tools (like unix logrotate) to do it for you.

......common/classes# cat log4j.properties
log4j.rootLogger=INFO, R
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=........./logs/tomcat.log
log4j.appender.R.MaxFileSize=30MB
log4j.appender.R.MaxBackupIndex=20
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n

development environment (for now and will implement to other
environments once I figure this out) using log4j.  I am running
apache-tomcat version 5.5.25 and downloaded the apache-log4j-1.2.15 and
commons-logging-1.1.1.  I copied the log4j.jar and commons-logging.jar
into the $CATALINA_HOME/lib and created the log4j.properties in the
common/classes.  However, when I stop and start the apache-tomcat the
cataline.out is not rotating.
