Look
particularly at "Servlets and JSP", "JSP Page Design", and "Application
Designs".
But
basically, ideally there should be no scriptlets (<% %> sections) in your
JSP page; and if there is, it should only be for outputting HTML and not doing
any actual actions. Any actions that need to be performed should happen
through custom tags, JavaBeans, and other Java classes.
That's real
nice in theory, but in practice it's very easy to cut corners and use scriptlets
here and there--it's a lot more time consuming to use custom tags and javabeans
for simple tasks.
Anyway,
explore the Blueprints site and I'm sure it'll start to become
clear.
