Configuration of the underlying logging system implementation is *not* the responsibility of commons-logging.
Understood.
That is up to your application. For Log4J, that means doing something like:
* Shipping a "log4j.properties" file in your app that Log4J will automatically recognize and use to configure itself.
Yeah, l may end up doing this - I was trying to avoid any config files to get "default" behaviour - in this case, showing only WARN level and up.
* Explicitly calling one of the Configurator methods to set things up the way you want.
Thanks - I had looked at these, but seemed to need the encapsulated Logger -- but Logger.getRootLogger() is fortunately static, I can setLevel on that. Works for me.
Has a commons.logging.Log.setLevel() been ruled out for architectural reasons? This would have kept my code generic.
Thanks, Thomas.

That's because SimpleLog is a (simple) logging system implementation, so it needed to provide a configuration mechanism.

That's the idea :-).
