Commons Logging - Log4J Configuration
If you use commons-logging in your java application, make sure to have log4j library (jar) and log4j.properties file on the class path. You really don't need much tweaking to get started :)
Simple log4j.properties file:
# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG, A1
# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender
# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
