I have tried to configure DSW in Karaf 4.0.3 via Felix fileinstall with a config file named "cxf-dsw.cfg". However, the framework never ends up calling the update method (ManagedService) of org.apache.cxf.dosgi.dsw.Activator. The problem probably is the syntax (against OSGi spec?) of the service PID (cxf-dsw). After updating the PID to "org.apache.cxf.dosgi.dsw" in org.apache.cxf.dosgi.dsw.Activator (and the cfg filename accordingly) things started to work.
