HomeController.java
package com.google;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
#Controller
public class HomeController {
#RequestMapping("/")
public String showMyPage() {
return "main-menu";
}
}
I have created main-menu.jsp page and kept it inside view folder inside WEB_INF. Also both xml files are in WEB-INF.When I am running ,I am getting this exception.Is it because of init-params, but I think it is correct, it should work fine. Then where is problem, please help.

Root Cause ....
java.io.FileNotFoundException: Could not open ServletContext resource [/WEB_INF/spring-mvc-demo-servlet.xml]
The error occurred, probably because the path to "spring-mvc-demo-servlet.xml" in the tag <param-value> WEB_INF / spring-mvc-demo-servlet.xml </ param-value> is incorrectly specified
