MVC-Central controller help needed

[vidya vani]

Hi
Can any one explain me what is the central controller in Model-View-Controller design pattern...

[Bear Bibeault]

I'm not sure what you mean by central controller. Did you mean front controller?

In any case, perhaps this article might help.

I Think you had asked about the servlet conttroller,
In MVC Pattern the controller is Servlet, if any request comes from
client first it hits the servlet controller after that it will navigate
to JSP's

If you mean it as a Controller in MVC, it's a central part of the MVC architechture, which gets the request from client, find out which Model(Business Logic) to process the request and in return it finds out which JSP has to be returned. if any error/exception occurs it forwards to error.jsp(example) else it forwards to appropriate JSP(View). Hope this explaination helps you. this you can get in google as well or in anybook.

what you exactly mean by central in you question.
