<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

and my controller looks like:
package org.vinay.spring_mvc.mycontroller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping(value = "/employee", method = RequestMethod.GET)
public class MyController {
public ModelAndView helloWorld()
{
System.out.println("Hello World");
return new ModelAndView("/hello");
//return new ModelAndView("helloWorld.jsp");
}
}
and the JSP from which Iam sending request is a welcome file of web.xml. i.e. index.jsp . it looks like:
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()path+"/";
%>
<%System.err.print("Path : "+request.getContextPath()); %>
<html>
<head>
<title>Solution Center</title>
<h5>Welcome To Solution Center</h5>
</head>
<body>
<a href="employee">hello</a>
</body>
</html>
Can anyone please help me why i am getting the below errors:
javax.servlet.ServletException: No adapter for handler [org.vinay.spring_mvc.mycontroller.MyController@18c8aea]: The DispatcherServlet configuration needs to include a HandlerAdapter that supports this handler
org.springframework.web.servlet.DispatcherServlet.getHandlerAdapter (DispatcherServlet.java:1128)

javax.servlet.http.HttpServlet.service(HttpServlet.java:803)
I tried using annotation based handler adapter also but got the same error. any help on this will be helpful.
I only figured out that I am getting this due to inclusion of mvc:resources tags. I f I Comment them my project works fine. Any help on them would be very helpful . I already have tried lot of other ways please provide me step by step solution. I am not able to solve this problem from last 4 hours.
Delete the following from your spring-servlet.xml
<bean id="handlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/employee">myController</prop>
</props>
</property>
</bean>
<bean id="myController" class="org.vinay.spring_mvc.mycontroller.MyController"></bean>
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>
Add <mvc:annotation-driven />
which will configure your application context automatically for use with annotated controllers.
See http://static.springsource.org/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-config-enable for more info.
