What is this SandBox?

Configuring (and more importantly, supressing) Tomcat 5.x logging

Create a log4j.properties file in $CATALINA_HOME/common/classes

log4j.rootLogger=ERROR, R
log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.File=${catalina.home}/logs/tomcat.log
log4j.appender.R.DatePattern='.'yyyy-MM-dd
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern={%p} %c{2} %x %m%n
                                                                                                                                           
                                                                                                                                          

You also need to copy commons-logging.jar and log4j-1.2.9.jar to $CATALINA_HOME/common/lib.

Then, in your application log4j.properties file, add this:

# Suppress the tomcat logging whilst DEBUG is switched on
log4j.logger.org.apache.catalina.core=ERROR
log4j.logger.org.apache.catalina.session=ERROR
log4j.logger.org.apache.jasper.compiler=ERROR

Because if, whilst developing, you set your root logger to DEBUG, then it seems to set the Tomcat logging to DEBUG as well, and you will probably witness thousands of lines of compilation trace from the Jasper compiler!
