在页面上总出现这个错误，但是在程序中不出现，这是怎么回事？怎么解决啊？

Answer 1

天啊，你没有导入strust2的jar包啊，再在web中配置

Answer 2

再web中怎么配置，我的包导入了

Answer 3

<filter>
        <filter-name>struts2</filter-name>        
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>
    <filter-mapping>
    <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>这是我的配置文件

Answer 4

跟你导入的struts2-core.jar有关 没有找到标签用的ActionTag类

Answer 5

看下org.apache.struts2.views.jsp包下有没有ActionTag这个类

Answer 6

org.apache.struts2.views.jsp包下有ActionTag这个类

Answer 7

看一下你的配置文件。struts2五大核心jar包 
<从下载的struts2框架中找出下面的jar包>1。Commons-logging.jar  --------------   用于通用日志处理2。Freeer.jar  --------------   表现层框架，定义了struts2的可视组件主题3。Ognl.jar  --------------   OGNL表达式语言，struts2支持该EL 4。Struts2-core.jar  --------------    struts2 2.0.11.2的核心库 5。Xwork.jar  --------------   webwork的核心库 如果要整合spring需要将这个jar包导入：struts2-spring-plugin.jar   --------------   struts2的spring插件

Answer 10

<%@ taglib uri="/struts-tags" prefix="s" %>
这样写的对不？

Answer 11

我曰，看是不是版本的问题啊。你也真够狠 的那么多jar包都放进去了吗？

Answer 12

版本？我用的是：struts2.1。8.1+hibernate3.1+spring2+woblogic服务器，+mysql+Myeclipse5.5GA

Answer 13

到下载的jar包中找到bank的压缩文件里面有例子和你需要要的jar文件

Answer 14

引入<%@ taglib uri="/struts-tags" prefix="s" %>  标签式 缺少actiontag类 先确认你的jar文件里有没这个类。没有的话就看包对不对 版本对不对

Answer 15

帮你找了个有这个类的核心包
http://mirrors.ibiblio.org/pub/mirrors/maven2/org/apache/struts/struts2-core/2.0.14/struts2-core-2.0.14.jar

Answer 16

http://mirrors.ibiblio.org/pub/mirrors/maven2/org/apache/struts/struts2-core/2.0.14/struts2-core-2.0.14.jar去下吧 然后把你之前的core删了 换这个

Answer 17

下载下来了，也替换掉了，还是原来的错误，struts2.0.1.4 jar包里有这个类，（我以前struts2用的是2.1.8.1,现在就把这个包改成1.4版本的可以吗？）

Answer 18

个人感觉是JAR包版本的问题！
