[slf4j-user] Re: Configuring JCL over SLF4J

[Kees de Kooter]

Thanks Heiner,

I did some more testing and found out that indeed Tomcat does not play
nice. Tomcat contains commons logging. CL is already loaded by tomcat
and as a result the jcl-over-slf4j is never used. And the log4j config
of my app is not used either.

I deployed CL with my app again and now all logging ends up in the
log4j log again. So my setup now is:

spring / hibernate --> JCL --> LOG4J
my code --> SLF4J - LOG4J

regards,
Kees
