I guess it depends a little bit on what you want to communicate and
when. Not sure about the Framework stuff, but what I did in another
project is to pass objects from the outside into the OSGi framework -
through the webapp context - these objects were loaded by a shared class
loader (the webapp classloader in this case and I had a fragment bundle
for this) and then I could call these objects from within OSGi services.
But obviously this is a very special solution which was fine in my case
but is maybe not suited for a general case :)
