AddController.java

package com.newApp;
import java.lang.*;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class AddController {
    @RequestMapping("/add")
    public void add() 
    {
        System.out.println("I am good");
    }

}

program should print "I am good" on the console but it is showing error on browser "The origin server did not find a current representation for the target resource or is not willing to disclose that one exists." on the console it is showing "No mapping found for HTTP request with URI [/demoApp/add] in DispatcherServlet with name 'newApp'".

This error accures when i click on submit button on jsp page.

If you want to use view technology like jsp. You could add bean definition of InternalResourceViewResolver class into your spring configuration file

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/view/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

see official docs

  • Still the same error. I can not understand why this is happening, please help. – Technical Untechnical Aug 05 '19 at 15:56
  • Maybe is incorrect url mapping? What is application context used during deploy at the server? You could see related [question](https://stackoverflow.com/questions/43931383/the-origin-server-did-not-find-a-current-representation-for-the-target-resource), it may have similar issue – Anthony Aug 05 '19 at 19:48

I got the same issue and resolved it. Please add missing folder src/main/java [add package name (for example: com.dev) while adding a class] and then add the java class in that instead of src/main/resource folder. This is the culprit. Let me know for any issue at parixitk28@gmail.com.
