I already read the documentation, I only omitted that logback was also considered as one binder as well So I can't have both slf4j-to-log4j and logback, this point is clear now At first what I wanted was to redirect all logs from log4j to slf4j and us logback as implementation, but it seems that the client-app.war use some log4j non-overload classes, not included into the bridge lib: log4j-to-slf4j.jar That s why I decided to go with the log4j implementation, but I forgot that even if logback support natively slf4, that still makes it one of the implementation, so it can't be both in use. My bad, I will test it, as I don't have direct dependency over logback with this library. I should work Thanks -----Message d'origine----- De : logback-user-bounces@qos.ch [mailto:logback-user-bounces@qos.ch] De la part de Ceki Gulcu Envoyé : mercredi 19 août 2009 10:52 À : logback users list Objet : Re: [logback-user] Redirecting logback logs to log4j Hello Johan, Could you please read the slf4j manual [1] and the page on Bridging legacy APIs [2]. Those pages contain the explanation you are seeking. However, if you are still confused about how to proceed, please contact this list once again.

Hi,
I designed component, packaged in jars, using slf4j and logback, this library is then packaged with a third party application using log4j.
I presumed that slf4j and logback could be used to change your log system depending on the loaded libraries of your classpath.
Here my configuration:
my_library.jar using only slf4j and at some point logback dependencies
included with it:
slf4j-to-log4j.jar slf4j.jar log4j.jar à already present in the war. logback-*.jar
All these libraries are installed into a third part webapp application (client_app.war), directly under the WEB-INF/lib directory of this application.
This application has a log4j.properties, in the classes directory, changes are made to create a log4j logger.
At my understanding, my librarys log events should be redirecting from slf4j/logback to log4j, using the log4j.properties, and so be written in the client_app..log configured?
Am I wrong?
Do I still need a logback.xml to be located under the classes of this webapps as well?

Johan Bos**
