log4j:WARN No appenders could be found for logger
I have a karaf custom build which has some 12 bundles. And have configured
log4j in some of the bundles.
I can see one of the bundle issuing the warning 'log4j:WARN No appenders
could be found for logger"
Other bundles works fine and logs go to the karaf.log file. Facing the
issue with only one bundle.
How to fix it. As far as i know, i didnt do any special configurations.

Hi,
You shouldn't configure log4j stuff in your customer bundle, all logging should be delegated to OPS4J PAX-LOGGING OSGI logging service, that said, you should configure log4j in $KARAF_HOME/etc/org.ops4j.pax.logging.cfg

I'vent encountered that problem by now. It could be a problem in your
exports/imports or some embedded libraries. You best chance might be to
check the content of your manifests.xml and bundle and compare it to your
other bundles.
Kind regards,
Andreas
