Günter,
I don't know if there is any standard support for navigation bars as you
describe. I made a similar functionality;
As you mention yourself ("business function context") navigation is part of
the business logic; so I made a navigation object which is maintained in my
action classes; the jsp's which display the navigation bar simple loop over
the navigation object and display it as illustrated by yourself.
So you setup the navigation in your action classes and the jsp's simply
display it.
