Extending the Logger class is strongly discouraged.
Anyway, the examples file mycat.good had a mistake. I have attached a corrected version. Try it first before continuing.

# Setting the category factory to MyLoggerFactory solves the # ClassCastException problem encountered with the "mycat.bad" # configuration file. log4j.loggerFactory=examples.subclass.MyLoggerFactory # The usual stuff. Note that A1 is configured in root not in "some.cat" log4j.rootCategory=DEBUG, A1 log4j.appender.A1=org.apache.log4j.ConsoleAppender log4j.appender.A1.layout=org.apache.log4j.PatternLayout log4j.appender.A1.layout.ConversionPattern=%5p [%t] %c - %m%n # Set the priority of "some.cat" to TRACE (defined in # examples.customLevel.XLevel). Since we specified MyLoggerFactory as # the logger factory, the following line willl also have the side # effect of instanciating a MyLogger object having the name # "some.cat". log4j.category.some.cat=TRACE#examples.customLevel.XLevel
