java lang ClassNotFoundException org springframework web servlet DispatcherServlet

0 votes

I'm using spring 3.1.0.RELEASE, tomcat 7 as my servlet container, eclipse indigo as my IDE, and the spring-webmvc-3.1.0.RELEASE jar file. jar containing the DispatcherServlet is there in the lib folder, however when I launch the programme, I receive the following exception:

java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet

please advise why i am getting this exception, and how to fix it.

EDIT: following are my configuration files:

1- .springBeans:

<?xml version="1.0" encoding="UTF-8"?>
<beansProjectDescription>
    <version>1</version>
    <pluginVersion><![CDATA[2.9.0.201203011806-RELEASE]]></pluginVersion>
    <configSuffixes>
        <configSuffix><![CDATA[xml]]></configSuffix>
    </configSuffixes>
    <enableImports><![CDATA[false]]></enableImports>
    <configs>
        <config>src/main/webapp/WEB-INF/checkout-servlet.xml</config>
    </configs>
    <configSets>
    </configSets>
</beansProjectDescription>

2- web.xml:

<web-app>
  <display-name>Checkout</display-name>

  <servlet>
    <servlet-name>checkout</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>checkout</servlet-name>
    <url-pattern>*.action</url-pattern>
  </servlet-mapping>

</web-app>

3- checkout-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"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">

    <context:component-scan base-package="com.myapp"/>

    <bean id="myService" class="com.myapp.MyService"/>

</beans>

also when trying to access any page in the application, i get the exception:

HTTP Status 404 - Servlet checkout is not available

type Status report

message Servlet checkout is not available

description The requested resource (Servlet checkout is not available) is not available.
