if you want your site to be maintainable, you need a proper architecture.
Embedding Java code in JSP isn't a proper architecture, a well designed MVC model goes a long way.
In general, it can indeed be said that sites not employing an MVC model won't work.
They're poorly designed, poorly programmed, and will as a result have many problems that will lead to a lot of downtime and user frustration.
