Exercise $5-2$ Create a new servlet$$In this exercise, you$$ll modify the HTML document for the Email List applica$-$ tion, and you$$ll create a new servlet that responds to the HTML document. This is comparable to what you did for exercise $5-1,$ but the details are repeated here.$1.2.3.4.5.6.7.8.9.$Open the ch$05\_$ex$2\_$email project that$$s in the ex$\_$starts directory.$$Add a servlet named TestServlet to the murach.email package and map that servlet to the $/$test URL.$$Modify the code for the servlet so it implements the doPost method and the doGet method, but not the service method.$$Modify the doGet method so it displays a message that says $$TestServlet Get$.$Modify the doPost method so it displays a message that says $$TestServlet Post$.$Run the project and enter the $/$test URL into the browser to run the test servlet. This should show that the test servlet works for the HTTP GET method.$$Open the index.jsp file and modify it so it calls the $/$test URL instead of the $/$emailList URL.$$Run the project and click the Join Now button to run the test servlet. This should show that the test servlet works for the HTTP POST method.$$If the project uses the web.xml file to map the servlet, delete the mapping from the web.xml file and use the @WebServlet annotation to map the servlet instead.$$Run the project and test the servlet to make sure that the new mapping works
