Answer 1

<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 定义图形验证码Servlet -->
<servlet>
<servlet-name>img</servlet-name>
<servlet-class>com.script.web.AuthImg</servlet-class>
</servlet>
看好像是没配置filter,你配置了没？

Answer 2

<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
</filter>
<!-- FilterDispatcher用来初始化Struts2并且处理所有的WEB请求。 -->
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

Answer 3

当然配置filter了，和二楼的一样，就是那样配的！

Answer 4

struts-default.xml这个文件应该默认放在src下面吧！或者你放在别地方没有指定！

Answer 5

我从Struts核心包里吧struts-default.xml拿出来放在src下部署还是这个异常!不过在myeclipse自带的tomcat上部署运行没有报异常，而在外置的服务器上部署时就会报异常！ 不知道哪儿的原因！外置服务器上也有两个工程，我也是用SSH做的！都没出过这个问题！

Answer 6

二楼说的对。你可以filter配置有问题。

Answer 7

我在myeclipse自带的服务器上就能正常部署！
web.xml配置如下：
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:beans.xml</param-value>
</context-param>    <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>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>

Answer 8

不应该，以前我做的项目都是这样放着tomcat下的，都没有问题！

Answer 9

我测试了好几编，发现在myeclipse内置的服务器上能正常运行，而在外置的tomcat6上不能运行，推测可能是服务器的原因，于是重新安装配置了一次外置的服务器，这样能正常运行了！不管怎么样，谢谢各位参与！
