It can be considered an appropriate question for the list, but
netiquette still says it should be asked on a separate thread.  The
topic is totally different from Frank's question, which boils down to
"how can I do what a view controller does for me without Shale".

Shale (or pure JSF, for that matter) has *no* facilities directly
related to container managed authentication.  That doesn't mean you
cannot use them together ... it's just that doing so is you combining
the technologies, not the CMA facility leveraging JSF (or vice versa).

You cannot assign a window target, even on a non-authentication based
request, using a RequestDispatcher.forward().  The *client* has to ask
for the result of a request to be returned to a particular target ...
the server has no portable (individual browsers might give you back
doors, like a custom HTTP header) way to control or influence that
decision.

So, you're going to have to do two things:

* Make your client do another request

* Make the client ask for that result with a "target" attribute set.

I'm afraid I don't do enough with frames or multiple windows to know
how to do this off the top of my hand, but any solution that works
with pure JSP pages will most likely also work with JSF (and therefore
with Shale).
