To answer this question, you need to understand the concepts of servlets in Java.

Option A) GenericServlet - This option is correct. GenericServlet is an abstract class that provides a generic implementation of the Servlet interface. It can handle any type of protocol and is protocol-independent.

Option B) HttpServlet - This option is correct. HttpServlet is a subclass of GenericServlet and provides specific implementation for handling HTTP requests. It is specifically designed for handling HTTP protocol requests and responses.

Option C) Both (A) and (B) - This option is correct. Both GenericServlet and HttpServlet are types of servlets. HttpServlet is a subclass of GenericServlet, so it inherits all the methods and functionality of GenericServlet.

Option D) None of the Above - This option is incorrect, as both GenericServlet and HttpServlet are types of servlets.

The correct answer is C) Both (A) and (B). This option is correct because both GenericServlet and HttpServlet are types of servlets in Java.

To answer this question, you need to understand the basic components of a web application in a Page-Centric architecture.

In a Page-Centric architecture, the initial contact point for handling a web request is typically a JSP (JavaServer Pages) page.

Option A) JSP Page - This option is correct because a JSP page is responsible for generating the dynamic content that is sent back to the client in response to a web request.

Option B) Java bean - This option is incorrect because a Java bean is a reusable software component that is used to encapsulate data and provide methods to manipulate that data. While Java beans can be used in conjunction with JSP pages to process data, they are not the initial contact point for handling a web request.

Option C) Servlet - This option is incorrect because a servlet is a Java class that is responsible for processing web requests and generating dynamic content. While servlets play a crucial role in handling web requests, they are not the initial contact point in a Page-Centric architecture.

Option D) Session manager - This option is incorrect because a session manager is responsible for managing user sessions in a web application. While session management is an important aspect 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) JSP Page. This option is correct because a JSP page is where the initial handling of a web request occurs in a Page-Centric architecture.
