The exception clearly says it! You need to have the commons logging also
into the  OSGi and the packages exported. You can either use  Pax Logging
http://wiki.ops4j.org//x/F  for ease or use osgified bundles of
commons-logging and log4j.

And frankly why would you want to import log4j packages, just use the
commons logging packages, it should be smart to use log4j implementation if
it is made available.
