I just recently subscribed to this list and have already found several
of your posts to be useful. Thanks for spreading the knowledge, Craig. :)
I've always liked separating presentation logic and will likely use a
JSP-Presentation/Servlet-Logic approach as you suggest. One aspect that
seems like it will be a hassle is preventing a user access to restricted
areas of the website. It looks like, for one request, I'll need to verify
that the user making the request is valid in both the servlet and the
JSP(since even jsp's meant to be called only from servlets can be typed in
as a URL) . Has this been your experience? I can derive my servlets from
some sort of ProtectedServlet base class to handle most of the checking
logic but it still seems like a pain. I hate to force all my JSP's to have
user-checking java code embedded in them since the goal is that a
non-programmer web designer can create all the presentation files.
Would taglibs help? I haven't found much documentation on taglibs so far.
