Thank you for your help Chris! I was able to get the JUL messages bridged to SLF4J and logged in the appropriate logback managed files. However, as a result I'm picking up a lot of "noise" from other packages. I've turned them down using the following configuration options (see below). Can someone tell me if there is a way to exclude them from the two appenders without affecting higher level handlers? For example, I'd like to ignore messages from "org.jboss.*" and let the container continue to handle its own logging. Unfortunately, setting the "org.jboss" level to "OFF" has a side-effect of disabling the container's logging too (server.log). Thank you! - D.

If you would like those bridged over to your Logback for processing, look into the SLF4j Bridge Handler (http://www.slf4j.org/api/org/slf4j/bridge/SLF4JBridgeHandler.html) (*Chris*) On Tue, Nov 20, 2012 at 1:40 PM, Pegram, David <dpegram@biosignia.com<mailto:dpegram@biosignia.com>> wrote: Greetings! I have a web app built with Maven I've added Logback to handle the logging with two rolling file appenders.
