Configure log4j.properties

Or log4j.xml: http://wiki.apache.org/logging-log4j/Log4jXmlFormat

In Java then either this: PropertyConfigurator.configure("log4j.properties");
or this: DOMConfigurator.configure("log4j.xml");
does the magic

log files should be saved in a group folder somewhere

Would this be set up so there is one config file that directs all output to a file somewhere as well as the console or would a seperate one of these have to be made for each class of logger.

Just one config - you can specify anything in it

Also, adjust logs by their severity:

TRACE,
DEBUG,
INFO,
WARN,
ERROR,
FATAL

Only strategy needs to do that now.
