In the context of JSP, the Model-View-Controller (MVC) pattern can be implemented by having the JSP act as the View to display data from the Model (usually Java objects) and the Controller can be represented by servlets or Java classes that handle business logic and interact with the Model. The JSP page is responsible for displaying the data provided by the Controller, maintaining a separation of concerns between the presentation (View) and business logic (Controller).

The Page Directive is one of the important components of any JSP Page. It can help us define page specific properties like Buffer size or location of an error page etc A JSP page, and any files included via the include directive, can contain one or more page directives but no duplicates. The JSP container will apply all the attributes to the page. The position of these page directives is irrelevant, but it is good practice to keep them together at the top of the page. (So that we can identify them easily)
