Basically you need put your customer append into a fragment bundle and append the fragment bundle to org.ops4j.pax.logging.pax-logging-service(pax-logging-service play the role as a host bundle)
Thank you freeman for this reply.
Could you send me some sample pom.xml Maven file which would enable me to generate this kind of bundle ?
I don't have a complete one at hand, but the key point is add Fragment-Host for maven-bundle-plugin, something just like
and you can google to get more details.
