Hi Jan, I believe you can put the log4j.properties into the <approot>/WEB-INF/classes and the log4j-<version>.jar and commons-logging.jar into the related WEB-INF/lib
see http://tomcat.apache.org/tomcat-5.5-doc/logging.html I tested with the following sample properties for test = DEBUG will generate lot of log. log4j.appender.myapp1.File=${catalina.base}/logs/myapp1.log log4j.appender.myapp1=org.apache.log4j.RollingFileAppender log4j.appender.myapp1.MaxFileSize=10MB log4j.appender.myapp1.MaxBackupIndex=10 log4j.appender.myapp1.layout=org.apache.log4j.PatternLayout # Print the date in ISO 8601 format log4j.appender.myapp1.layout.ConversionPattern=%d [%t] %-5p %c - %m%n log4j.logger.org.apache=DEBUG, myapp1 It would be interesting to know if there is a way to get this to work without copying the jars into the lib dir and also what a typical log4j.properties should be to be helpful in a production environment.
