What is servlet mapping?
A Servlet Mapping is a directive in the web.xml that tells the Servlet Container which class to use when a particular Servlet is called. A Servlet is a class within your Java Web Application. Let's say you have a servlet called MyServlet in the com.example.servlet package. You would need to have a Servlet Mapping pointing the path "/MyServlet" to the "com.example.servlet.MyServlet" class. Without the servlet mapping, you would not be able to invoke your servlet because the Servlet container would not know where it is. JSPs are different - they do not need mappings like this. JSPs exist within the WebRoot of the application, so they are always available. Servlets exist in the WEB-INF\Classes directory once your application is deployed.
How to retrieve data from jsp to servlet?
To retrieve data from a JSP to a servlet, you can use form elements in your JSP to collect user input and submit it to the servlet.

In the servlet, you can access the submitted data using the request.getParameter("parameterName") method, where "parameterName" corresponds to the name attribute of the form input elements. This allows you to process the data as needed in your servlet.
