It decouples the presentation
tier with business tier. So from JSP you never has to access EJB or DAO
directly,
It is done through "View Helper" in the
form bean (JSP usebean) or as JSTL tags.
But with MVC, JSP never have to access
business logic directly, only state needs to be passed to JSP for
rendering.
With WEB2 (Rich internet apps), this could
change as "data" resides in client as well.

Subject: View helpers
Can anyone offer a simple example of the view helper pattern? I understand the gist of it, but can only find explanations for Java in which i get a little lost with javaisms. A flex orinetated sample or metaphoric explanation i think should help.
Cheers,
Dan
