Well if you need to "extend" your war with additional Servlets you need to stick to the std. OSGi-Fragments cause only with those they are in the same context. Or you try to break it up into a std. osgi jar and register all Servlets via the WhiteBoard Extender using the same HttpContext which you need to register beforehand as a service also.
