按照书上的说法，我tomcat是6.0,支持web-app2.4,按照如下方式配置web.xml应该是可以的：



<?xml version="1.0" encoding="UTF-8"?>

<web-app 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">

	<context-param>

		<param-name>contextConfigLocation</param-name>

		<param-value>classpath:applicationContext.xml</param-value>

	</context-param>

	<listener>

		<listener-class>

				org.springframework.web.context.request.RequestContextListener

		</listener-class>

	</listener>

</web-app>

applicationContext.xml:
