processRequest(OAPageContext pageContext, OAWebBean webBean) in OAF?

You can see this Method in Controller(CO).

This method is used whenever we want any logic to be implemented before the page gets loaded.
It means while loading a page if we want to display (or) perform any business logic then we go for process request.

It is same as WHEN-NEW-FORM-INSTANCE in Oracle Forms.


Sample code when you create new controller , this is default code.
