Hi Johan,

thanks for the pointer. To me it looks like it does have a different scope.
Pax Web has been one of the first OSGi HttpService providers with
additional support for Web Application Bundles (std. war with OSGi Manifest)
This has been achieved so far very successfully with Jetty. Now we try to
add additional Containers like Tomcat and Undertow.
As for this Pax Web needs to be the one in control over registering
Servlets etc. by either HttpService registration, Whiteboard registration
or by using the bundle-extender approach.
You could regard this to be a mediation layer between the OSGi Service
Registry and the underlying web-container.

regards, Achim
