Explanation

Servlet mapping is the association between a URL pattern and a servlet, defined in web.xml (or annotations). It tells the container which servlet should handle requests matching specific URL patterns. ServletContext is shared data across servlets. Lifecycle refers to servlet initialization/destruction. The mapping mechanism is essential for routing requests to correct servlets.

AI explanation

To answer this question, you need to understand the concept of servlet mapping.

Option A) ServletContext - This option is incorrect because ServletContext refers to the interface that represents the servlet's view of the web application. It provides information about the web application and allows the servlet to interact with its environment.

Option B) Servlet mapping - This option is correct because the association between a URL pattern and a servlet is called servlet mapping. Servlet mapping is defined in the web.xml file or using annotations in the servlet class. It specifies which servlet should handle requests with specific URL patterns.

Option C) Lifecycle - This option is incorrect because the lifecycle of a servlet refers to the series of steps that a servlet goes through from its instantiation to its destruction. It includes methods like init(), service(), and destroy().

Option D) None of the Above - This option is incorrect because option B, servlet mapping, is the correct answer.

The correct answer is B) Servlet mapping. This option is correct because it accurately describes the association between a URL pattern and a servlet.
