When -Dlog4j.debug=true is set, Log4j prints its configuration progress to System.err.  With this, you should be able to see which config file is being picked up.

You can run your appender at a specified time by not placing log4j.properties in the classpath.  But then you'll have to manually configure it at some later point.

Note that if you also place a log4j.jar with WEB-INF/lib and another Log4j config file in WEB-INF/classes of your webapp, you will get a separate logger repository from the server containing a different configuration.  If you remove your config file from WEB-INF/classes, you'll still have a separate logger repository from the server but use the same config as the server.

Where did you put log4j.properties?  For Tomcat 5.5.xx, it should be in
CATALINA_HOME/common/classes.

Try adding the following to CATALINA_OPTS....

-Dlog4j.debug=true

Hi Jake

Thanks for the quick reply. is there a way to run log4j appender at a
specified time?

log4j.rootLogger=INFO, R
log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.File=${catalina.home}/logs/catalina.out
log4j.appender.R.DatePattern='.'yyyy-MM-dd
log4j.appender.R.layout=org.apache.log4j.PatternLayout

I have put the log4j.properties under /opt/tomcat0/common/classes and
have added -Dlog4j.debug=true under CATALINA_OPTS variable.
where do i look for the debug logs.

Please suggest.

Thanks and Regards

Kaushal
