Aiuto in Java

Buon pomeriggio,
ho un problema con Spring MVC Web.
Ho un problema.
Ho provato tantissimi procedimenti ma mi da sempre sbagliato.
SEVERE [87] org.apache.catalina.core.ApplicationContext.log Servlet.init() for servlet [dispatcher] threw exception
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'urlMapping' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'indexController' available
Non so più cosa aggiungere o togliere o modificare.
Grazie.
Ciao

Inserisco dispatcher-servlet:

<?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"  
           xmlns:mvc="http://www.springframework.org/schema/mvc"  
           xmlns:p="http://www.springframework.org/schema/p"  
           xsi:schemaLocation="

    <mvc:annotation-driven />
 
<bean id="urlMapping" 
      class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="mappings">
        <props>
            <prop key="/WEB-INF/jsp/index.htm">indexController</prop>
        </props>
    </property>
</bean> 

<bean id="viewResolver"
      class="org.springframework.web.servlet.view.InternalResourceViewResolver"
      p:prefix="/WEB-INF/jsp/"
      p:suffix=".jsp" />

<bean name="indexController"
      class="org.springframework.web.servlet.mvc.ParameterizableViewController"
      p:viewName="index" />
     
</beans>

Inserisco web.xml
