1) Use Reflection API
2) Configure web.xml and configure <servlet> and <servlet-
mapping>. Send request to the URL. If it is not servlet
then will throw exception like
javax.servlet.ServletException: Class
com.request.TestServlet is not a Servlet

Can anyone please tell me the workflow of how the servlet will get this arraylist and populate the arraylist values as dropdown options in jsp page?
