I m trying to use web application with Embedded tomcat 8 without web.xml.
But I am not able to access the application by hitting the url http://localhost:8085/Servlet_Basic/index.jsp from browser.
Neither I am able to access the servlet by hitting the url http://localhost:8085/Servlet_Basic/hello from browser.
Here is my source code :

How can I access the application and invoke servlet annotated with @WebServlet
annotation in embedded tomcat without using web.xml ?
Basically I want to use web application with embedded tomcat without web.xml and without explicitly configuring servlets using tomcat.addServlet() method.
Instead I would like to configure servlet using @WebServlet annotation
