Configuration of web.xml and spring dispatcher-servlet.xml for spring

Question

I am very new to spring framework so when I am trying to making a simple spring MVC program my server shows this exception report(class not found exception precisely):

If picture is not visible properly then please check complete error list below: enter image description here

I have already added spring distribution jars, commons-logins jar and servlets etc.

My XML files are as follows:

web.xml

<web-app id="WebApp_ID" version="2.4"
   xmlns="http://java.sun.com/xml/ns/j2ee" 
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

   <display-name>FirstSpringMVCProject</display-name>

   <servlet>
      <servlet-name>spring-dispatcher</servlet-name>
      <servlet-class>
         org.springframework.web.servlet.DispatcherServlet
      </servlet-class>
   </servlet>

   <servlet-mapping>
      <servlet-name>spring-dispatcher</servlet-name>
      <url-pattern>/</url-pattern>
   </servlet-mapping>

</web-app>

and

spring-dispatcher-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://www.springframework.org/schema/beans"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   
    xsi:schemaLocation="http://www.springframework.org/schema/beans  
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">  



    <bean id="HandlerMapping" class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>

    <bean name="/welcome.html" class="com.gontuseries.hellocontroller.HelloController"/>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  

        <property name="prefix" value="/WEB-INF" />  
        <property name="suffix" value=".jsp" />  
    </bean>  

</beans>

`java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet` are you missing a library or an import? — Celeo, Sep 24 '14 at 22:32

Can you post here the list of libraries you've added to your project? — Desorder, Sep 24 '14 at 23:34

I have faced the same issue when working with Spring MVC with Eclipse. What happens is that the dependencies are added to the classpath of Eclipse. However the next step is misssed

1) Add the dependencies to the classpath using : properties > buildpath - option on the project in eclipse

if you have already added the dependencies you would want to do the next step for web apps

2) Go To Deployment Assembly (project > properties > Deployment Assembly ) click on add : choose "Java Build Path Entries" Select the dependencies added. Click Finish.

Step 2 should ideally resolve your issue.

This is the list of required dependencies for a plain Spring MVC web application.

enter image description here

You can download/clone/look the project at

https://github.com/desorder/spring-mvc-test

It's a eclipse project.

@pushpendra Have a look at my github project and compare with yours. I don't know what the problem in your project is but it might be a very small detail. – Desorder Sep 25 '14 at 00:41

Spring would be like a country:

dispatcher-servlet.xml is the post office for the mail in Spring town, every letter should go through them, but some people keep on sending things with the old web.xml county office (which should be only an intermediary), which is a part of the country that was once great and independent, but now is just a district. May be old and not fancy, but it worked nicely when administered appropriately, some areas of the web.xml county have roads that lead to cliffs 404 meters in deep.
