The idea started a couple of months ago in one of my post.

Logging stuff in enterprise applications is really a tough task. Actually, logging introduces a paradox: on one hand logging is really critical when someting went wrong ; on the other hand, nobody cares about logging when everything is just fine. We, as developers, have to really take that into account.

The logging service is a very dumb service which allows you to reconfigure live your log4j configuration. The source and binaries are available in my maven2 repository
