Thanks Achim ! I am a bit lost in all thanks...
Karaf use pax-loggin-api which declare org.apache.log4j.Logger which is more an fork/implementation /rewriting is it write ? I have the feeling that I should investigate more with pax-loggin-api . I have removed my log4 dependancy and replace it with pax-loggin-api and pax-loggin-serice dependancy and indeed there are no removeAllAppenders method in it. 2014-06-26 10:49 GMT+02:00 Achim Nierbeck [via Karaf] < ml-node+s922171n4033807...@n3.nabble.com>: > Well, > > Pax Logging does provide a couple of different APIs for logging: > log4j, slf4j commons-logging, etc.. > > So actually it's a service that hides a lot of details from you. > As it is using log4j as the underlying logging infrastructure you most > likely are tempted to use a lot of it, > though those "internal" classes aren't available. > Take a look at the pax-loggin-api bundle and it's exports there you'll > find all packages available to you for usage. > If you want to have a custom Logger, you'll need to add it to the service > bundle as described in the various samples given by me and JB. > > regards, Achim > > > > 2014-06-25 19:02 GMT+02:00 loky <[hidden email] > <http://user/SendEmail.jtp?type=node&node=4033807&i=0>>: > >> Thanks jbonofre and Achim for helping me :) >> >> >> jbonofre wrote >> > latest section: "Custom appenders". >> > jbonofre > Pax Logging provides log4j 1.2.15. >> >> Indeed !
