How to make Pax logging to use the loggback config instead of the standard log4j properties like syntax

问题

I have some services in tomcat and trying to move to apache karaf.

I have a existing service which uses logback for logging configuration.

I tried to make same configuration in osgi, but could not achieve. Any please let me know what could be the problem?

  org.ops4j.pax.logging.cfg
         org.ops4j.pax.logging.logback.config.file=${karaf.home}/etc/logback.xml

logback.xml is available at ${karaf.home}/etc/ --.

Apache Karaf version : 3.0 , pax logging 1.7.1 which is packaged with karaf from build.

After above configuration change, my karaf.log contents are :

   Jul 02, 2014 4:21:32 PM org.apache.karaf.main.lock.SimpleFileLock lock
   .....................................................................
   INFO: Lock acquired
   Jul 02, 2014 4:21:32 PM org.apache.karaf.main.Main$KarafLockCallback lockAquired
   INFO: Lock acquired. Setting startlevel to 100

回答1:

The logback backend of Pax Logging is in a separate bundle mvn:org.ops4j.pax.logging/pax-logging-logback/1.7.1 which is not part of Karaf.

So if you didn't install this bundle manually, then it's no surprise that your logback.xml gets ignored.
