Are you sure you mean "forward"? The example you provided wasn't a forward.
You can forward inside the Struts framework to any path you want, action
or not, by putting the complete path in your forward definition:
<forward name="foobar" path="/BazServlet"/>
Then when BazServlet is replaced by an action you'd just change the
forward name. In your example, however, you're putting the contents of a
servlet into a frame, which isn't a Struts forward, and it's outside of
the Struts framework, so you don't have transparent access to anything
inside Struts (like the forward definitions).
The forwards defined in Struts config are designed to be used within
Actions (or their helpers) by saying things like:
mapping.findForward("name_of_forward");
If that page is being generated by a Struts/JSP (or other presentation
methodology) you could, say, put the forward's target into an
appropriate scope and render it via scriptlet, JSTL, or your
presentation side's equivalent.
I could be completely misunderstanding the problem, too. But it seems
like you want access to Struts from the outside, not access to the
outside from _inside_ Struts (which is trivial). It's still doable,
perhaps someone more knowledgable than myself could talk about accessing
the Struts config from the outside, or you could parse the parts you're
interested in, or something.

What am I doing wrong?
Mixing Struts and servlets ;)
Creating a forward doesn't create an action--what is logonServlet.do? If
it isn't an action, then why would it have a .do extension? When the
request processor sees a .do (if you're set up to do extension-based
struts mappings) it'll try to fire an Action.
Also, you can't use a forward definition in a non-struts anything,
because only struts knows about forwards.
If you are just using a servlet as the contents of a frame then you
don't need to interact with struts at all.
