Re: [logback-user] Ignoring specific packages?

26 Nov 2012

      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!

There's an extremely good probability that those statements are being written to the java.util.logging subsystem.  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)

Greetings!

I have a web app built with Maven I've added Logback to handle the logging with two rolling file appenders. Unfortunately, some exceptions (below) still bubble up to the server.log and are not captured in the logback generated files. How can I capture these with logback and keep them out of server.log?

Below are the relevant configuration pieces.

Thank you for your help!
