This video discusses Log4j and the log4j properties file. We discuss how to implement Log4j with a Maven-enabled Eclipse Dynamic Web Application with Tomcat.
Note that I have the logging levels incorrect in the video. The proper order, from most severe to least severe, is:
FATAL
ERROR
WARN
INFO
TRACE
ALL
Typically, the more severe, the less verbose. In other words, you'll usually see quite a few TRACE, and (hopefully) not many FATAL.
