Gregor says: Output of an "included
action" in a JSP. I think I understand this.
I do something like it for my "Struts Inside of
Struts" project. In doing so I am pushing the FormBean concept to its
logical (and absurd) conclusion.
My FormBean contains only a StringBuffer
attribute. The View JSP for this is extirely empty (almost) except
for the expression of the StringBuffer.
The function of my (outer) Action is to just invoke
an HTTP session on an inner Action (a Struts Action in some other application on
some other server), then to capture the HTML output of that HTTP
session, to modify some of its critical tag attributes and, finally,
to stuff that HTML character stream into the StringBuffer of the
ActionForm.
I really thought that this would have horrible
display latency before I tried it. Not really. Its almost
bearable. But don't try it 3 deep.

PS.
By the way, Struts works nicely for this absurd
usage. I will still claim I honored MVC, although my View is vacuous
and the Model knows damn well how it is to be rendered
(almost). One disappointment in all this
is java.net.HTTPSession. It doesn't deal cookies, so this
implementation has problems for Session Tracking under
Struts.
I am not the only person displeased by
java.net.HTTPSession. There are alternative classes that produce can
transfer cookie values (from Tigris, for example). I just haven't
tried any of them yet.
N.B., however, with respect to Struts, that
if my action form's (viewable) text is really
huge, StringBuffer is not goint to work out. Struts would have to be
re-architected into producer-consumer threads for the Model logic and the View
(rendering) logic, respectively. This is an interesting
thought.
