I am getting a HTTP Status 500 - Servlet.init() for servlet HelloWorld threw exception - spring

Question

Looked int other posts of "Servlet.init() for servlet " didnt help.
This is not a Maven or Gradle, so no pom.This is a plain simple spring project, which I am still struggling with. Below the snippets is the actuall error.
Hellocontroller.java.
package controller;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
import org.springframework.web.servlet.*;
//import com.sun.javafx.collections.MappingChange.Map;
public class Hellocontroller implements Controller {
#Override
public ModelAndView handleRequest(HttpServletRequest req,
HttpServletResponse res) throws Exception {
String name = req.getParameter("name");
Map m = new HashMap();
m.put("msg", "Hello ...."+name);
ModelAndView mav =new ModelAndView("success",m);
return mav;
}
}

Answer 1

There's an error in your configuration. The class org.springframework.web.servlet.InternalViewResolver doesn't exist (could it be you copy/pasted this from an ancient spring mvc example?).
Try replacing it with org.springframework.web.servlet.view.InternalResourceViewResolver. I cannot guarantee it works, but it's worth trying.
