Struts

Introduction:

The view is the presentation component of the MVC pattern. we see that the result returns the page to the web browser. This page is represent the user interface application’s state. These are commonly JSP pages, Velocity templates, or some other presentation-layer technology .While there are many choices for the view, the role of the view is clear-cut: it translates the state of the application into a visual presentation with which the user can interact .With rich clients and Ajax applications increasingly complicating the details of the view, it becomes even more important to have clean MVC separation of concerns. Good MVC lays the groundwork for easily managing the most complex front end.
