There may be some confusion here about "calling modules". That's not
really what happens. A module is a way to organize code, basically.
So when you say "I should call the entry page", that refers to having
the browser, via link or redirection or whatever, load the html for
your "C" application. That's correct. I'm not sure then what you
mean by "redirect to the "page" I want. You should be there already.

Well, if the button push is selecting something at a finer level of
granularity than the 'sub-application', then you could use the
Window.Location.* methods for examining the URL, if that information
is encoded there.

How you do this depends on what kind of state management you need. If
it's sufficient to back to an initial state in the front page of the
struts app (if that even means anything), then these buttons can act
like links and in effect do an HTTP GET on the front page.
Window.Location.replace will do that, by the way, from within the
button's click handler. But if you really mean "go back", then maybe
it's History you want.

That would seem to me to complicate things. Must you?
