To answer this question, you need to understand the concept of a Page-Centric architecture.
In a Page-Centric architecture, the web request is first handled by a specific page. Each page is responsible for handling a specific request and generating the appropriate response.
Let's go through each option to understand why it is correct or incorrect:
Option A) A JSP page - This option is correct because in a Page-Centric architecture, a JSP (JavaServer Pages) page is often used as the initial contact point for handling a web request. The JSP page contains a mix of HTML and Java code and can be used to generate dynamic content.
Option B) A JavaBean - This option is incorrect. A JavaBean is a reusable software component that follows certain naming conventions. While JavaBeans can be used in a Page-Centric architecture, they are not the initial contact point for handling a web request.
Option C) A servlet - This option is incorrect. A servlet is a Java program that runs on a web server and handles client requests. While servlets can be used in a Page-Centric architecture to handle web requests, they are not the initial contact point.
Option D) A session manager - This option is incorrect. A session manager is responsible for managing user sessions in a web application. While a session manager is an important component of a web application, it is not the initial contact point for handling a web request in a Page-Centric architecture.
The correct answer is A) A JSP page. This option is correct because in a Page-Centric architecture, a JSP page is often used as the initial contact point for handling a web request.
