While it won't provide an answer, you may gain some insight by reading
http://www.aptura.com/technology/jspBook_Architectures.html . I'll warn
you, I haven't finished writing it yet. It is part of an effort by
several people to write a "book" on JSP.

Subject: Servlet->JSP question
>Hello.
>
>First of all, I am new to this list, so if the question I am asking was
>previously covered, please point me to the appropriate archive (and
accept
>my appologies)
>
>I am trying to build an application that separates business logic from
>presentation (i.e. I want to allow my designers to work separately from
>programmers).
>Most "large" systems that do that (like Locomotive), although do a good
job,
>require their proprietary engines - i.e. they are not fully servlet
comliant
>and can't run under a generic Servlet runner.
>Couple systems that I looked at - WebMacro most notably - provide
excellent
>functionality, but, again, are not standards based (i.e. they have a
>proprietary markup language).
>So now I am settling on Servlet/JSP combination, where the servlet
performs
>all processing, then constructs a bean with data, selects a JSP pages and
>uses it to render the data. (This can easily be changed to XML, for
example,
>by using XML/XSL parsers to process the bean, instead of the JSP engine).
>
>My two questions are:
>1) Does this look like a sound architecture choice? (Any other
suggestions?)
>2) How do I invoke JSP from a servlet? In JSDK2.1 there is
>'RequestDispatcher.forward()', but that seems to allow the browser to
access
>that JSP page directly (i.e. if I can call 'forward("/foo.jsp")', the
browser
>can call 'http://myhost.com/foo.jsp' [ignoring the incorrect semantics of
>'forward' I used] ) - which is really bad (and I do not want to get into
the
>game of setting the web-server to disallow access to certain pages from a
>browser).
>
>Thanx in advance for your help.
