You can't really forward from one JSP to another, because by the time you
get control, it has already opened an output stream on the output socket.
Thus screen logic control in a JSP would be a series of includes, which
would be pretty clumsy. Other than that, it wouldn't be terrible to let
beans do the work of figuring out which JSP to go to.
Since screen logic is mostly a programmatic task anyway, and the servlet API
already has a request forwarding API, it naturally follows that you build
your screen logic in a servlet, data model in beans, and output display
presentation in JSP. Each is designed for it's own particular purpose. Why
do you want to swim upstream anyway? :-P

Subject: Why use Servlets with JSP?
> Please pardon me if this is down a beaten-down track, but I really fail to
> understand the point of using servlets with JSP. JSP is one level higher

on

> Second, more ISPs support servlets than they do the JSPs, naturally. I
can't
