Jsp and spring problems

I am doing some test with Spring and I want to use jsp´s
I have defined a jsp

Code:

<%@ page session="false" %> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>

Code:

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

When I try to call the jsp I receive this error:
