Bill,
I'm sure it's me but I had difficulty visualizing scenario (2). I think it's
saying that the servlet would be contacted first, the servlet does some
work, the servlet invokes the JSP page for formatting, the JSP page returns
formatted HTML to the servlet, the servlet returns the formatted HTML to the
client. Is that what (2) is saying?
Sincerely,
Wes Williams
