Thanks Pavel. Sounds like it might be simpler for me to create a separate filter for the servlet and refactor as much of the authentication code as possible into a class that the 2 filters share.

Subject: Re: Use a ContainerRequestFilter with a plain old servlet?
Hi Terri,
there is no simple way how to do that without involving Jersey, also it
doesn't really make sense.
What you could do is to register Jersey as a Servlet Filter and do
implement your filter there, as pre-matching. Then don't add any
resource into the filter (you might need to add a fake one, maybe there
is a condition that the Application cannot be empty - I'm not sure now,
you'll need to test it by yourself.
Then make sure that FILTER_FORWARD_ON_404 [1] is set to true. Your
pre-matching filter will be invoked, but all "passing" invocations of
the stack should result in 404, which would let Servlet impl continue
with another item on the process chain (that would be your JAX-RS-less
Servlet).
Hope it helps,
Pavel
