我在jsp文件中写了这样一行
<%@ taglib prefix="s" uri = "/struts-tags" %>
用eclipse可以找到struts-tags这个文件
导入的jar文件有以下几个
commons-logging-1.0.4.jar
freemarker-2.3.8.jar
ognl-2.6.11.jar
struts2-core-2.0.14.jar
xwork-2.0.7.jar
HelloWorld.jsp文件为
[code="java"] <%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@ taglib prefix="s" uri = "/struts-tags" %>
访问 HelloWorld.jsp文件时，产生错误信息如下，红色是我认为的关键颜色。向大家请教，我哪里错了
org.apache.jasper.JasperException: Exception in JSP: /HelloWorld.jsp:10
7: < title > Hello World! </ title >
8: </ head >
9: < body >
10: < h2 >< s:property value ="message" /></ h2 >
11: </ body >
12: </ html >

root cause
[color=red]The Struts dispatcher cannot be found. This is usually caused by using Struts tags without the associated filter. Struts tags are only usable when the request has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag. - [unknown location][/color]

你这多了空格啦
改成
[color=red][/color]
我想你这个代码肯定是从其他地方复制过来的. 我发现里面好多地方都多了一些不明白的空格,我再帮你整理了一下
[code="html"]<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %><!-- ltd包的引用必须放到上面,这个是正规的写法 -->
