Hi Antonio,
whats about coupling the log settings to "run levels"?
Every application server I know comes with "development" and "production" stage.
We could rely on the spec packages and use then something like:
javax.ejb=production (whatever it means for Log4j -> mapping would be server-specific)
javax.rs=development
javax.enterprise.inject (but now org.weld)
etc.
I see a problem with your proposals, that the specifiied log levels do not have to be available for each framework (log4j, java logging, etc.).
thoughts?

Modules to exclude in one, jars to add in the WEB-INF/lib on the other... or to exclude. And of course, that's just my application Log4j logs. If I want to have more logs on javax.ejb I need to setup a different file in JBoss and another one in GlassFish.

Every application uses logs. Every framework uses logs. Every Java EE spec implementation uses logs. For an application to be portable across app servers, for a configuration file to be portable across Java EE specs, we should do something.

Gosh, I just want to display some logs, why do I have to choose from 10 different frameworks and why should I battle with app server configuration.
