Use logback instead of log4j

[Former user]

Logback is the native implementation of SLF4J. His creator founded another project before : Log4j !

2 steps to switch :

replace log4j jar by logback jar

update xml configuration

what will this bring that log4j doesn't have?

The killer feature is speed : it's an evolution not a revolution... Other nice features are:

• Automatic reloading of configuration files
• Automatic compression of old log files
• Dynamic filters at runtime (to debug specific need)
• JMX / MBeans configuration access, Servlet configuration access ...
