Log4j looks on your class path for a properties file
"log4j.properties". If you put the file in WEB-INF/classes
it will find it.
Here's a real simple example:
log4j.rootCategory=DEBUG, dest1
log4j.appender.dest1=org.apache.log4j.RollingFileAppender
log4j.appender.dest1.file=/usr/local/tomcat/logs/myapp.log
log4j.appender.dest1.layout=org.apache.log4j.PatternLayout
log4j.appender.dest1.layout.ConversionPattern=%-5p: %m%n
