Now I have logging working. Using log4j-1.2.9 My application is 'hub'
put the properties file named log4j.properties in tc's classpath (I use webapps/hub/WEB-INF/classes ) put the log4j-1.2.9.jar into webapps/hub/WEB-INF/lib Init as follows: //jakarta log4j import org.apache.log4j.*; import org.apache.log4j.BasicConfigurator; import org.apache.log4j.Level; Logger lg = Logger.getLogger("hub1"); The 'name' (hubl) is arbitrary, read the log4j manual for more. then use as needed, e.g. lg.error("** hub logging started **"); The properties file I used is below. It produces output in ${catalina.home}/logs/tomcat.log as specified in the properties file log4j.rootLogger=DEBUG, hubl #log4j.appender.hubl=org.apache.log4j.ConsoleAppender log4j.appender.hubl=org.apache.log4j.RollingFileAppender log4j.appender.hubl.File=/tomcat559/logs/tomcat.log log4j.appender.hubl.MaxFileSize=1MB log4j.appender.hubl.MaxBackupIndex=3 log4j.appender.hubl.layout=org.apache.log4j.PatternLayout log4j.appender.hubl.layout.ConversionPattern=<e><t>%d{yyyy-MMM-dd HH:mm}</t><lvl>%-5p</lvl><m>%m</m></e>%n You may not want output in XML format, in which case again go do some reading. http://logging.apache.org/log4j/docs/api/org/apache/log4j/PatternLayout.html (warning, long url) provides the full story. http://logging.apache.org/log4j/docs/manual.html is worth reading, and I found http://supportweb.cs.bham.ac.uk/documentation/tutorials/docsystem/build/tutorials/log4j/log4j.html to be useful. Perhaps the tomcat documentation might benefit from such a tiny inclusion?
