In my case I used Ivy and I faced the same issue. You can do either of the two

  1. Either move your libraries to WEB-INF/lib . Because this is the folder from where Eclipse searches for corresponding jars. OR
  2. Let Eclipse know that it can search the jars from ivy library folder which is not same as WEB-INF/lib i.e Change java build path in Deployment Assembly via Project properties.

For 2nd approach you can refer to my personal blog post - details post with screenshots. Or you can also go through similar question I asked here.

Might be you are missing viewClass try with this

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

and you can update spring dependency as

    <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>3.2.1.RELEASE</version>
</dependency>

and check your jar files have been dowbloaded in your .m2 folder / check it in lib folder
