I use the OSGi Http Service Specification to register my Servlets.  My question 
addresses more of what to after the Servlet gets a request and needs to access 
some OSGi service for instance.  I can't figure out a clean way to wire my 
Servlet up with the rest of the OSGi univers.

Have you seen if the OSGi Http Service Specification meets your requirements?

If not, take a look at the Servlet Bridge by Simon Kaegi.

Also, you can embed Felix so that framework extensions, which are
loaded from your servlet with the embedding, can expose and use
services in the Felix instance. I guess Equinox can do the same, but I
don't know the details.
