First of all, if you want to have a working logging with Karaf, use the
logging provided by it.
Karaf uses Pax Logging which supports a wide range of logging frameworks.
So don't embed log4j in your bundles. It's not needed and just doesn't work
that way!
You also should check the way you do your logging. Either you have a custom
appender which needs to be registered in a different way.
Or you doing something else strange.
Cause usually a logging like the following is sufficient:
LoggerFactory.getLogger(LoggingClass.class);
log.error("this is my error message with content {}", content); //slf4j
style logging
For using a custom appender (or something similar), you either might check
the mailing-list or take a look at [1].
