I think I see how it works. So you are trying to define a way to navigate
between different servlets, and keep the servlets within a portal window?
Not sure if I understand this "top-level" concept?
Are you saying that is Jetspeed?
If so, isnt it better to do something like $link and get it dynamically
I guess the problem I have with this is that it assumes that all servlets
will have to know about the fact that they are working within a portal,
which normally is not the case
