我加入了struts2的相关包 但是不知道是为什么会有这中情况
我也检查了相关的配置文件 没看出什么问题

[tanli902354]

在 web.xml 中 这句关于 struts2 的配置有吗?
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
</filter>

<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

如果有
根据 com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.loadConfigurationFiles(XmlConfigurationProvider.java:839)
异常 可能就是少了哪个jar 包
commons-fileupload-1.2.1.jar
commons-io-1.3.2.jar
commons-logging-1.1.jar
freemarker-2.3.13.jar
ognl-2.6.11.jar
struts2-core-2.1.6.jar
xwork-2.1.2.jar
最少需要 以上的jar包 检查下 是否有少
希望能够解决你的问题

[redlotus_lyn]

缺少commons-fileupload-1.2.1.jar


struts2.1.6，struts2.1.8和struts2.1.8.1

要加commons-fileupload-1.2.1.jar

[hongyu5920]

学习了！

[zhangsiwei_1001]

web.xml中struts2过滤器配置了吗?
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
<init-param>
<param-name>config</param-name>
<param-value>struts-default.xml,struts-plugin.xml,struts2/struts.xml</param-value>
</init-param>
</filter>

应该是你导的包不对吧。

[soli11722984]

包冲突了？？？

[lixiccgccyuan]

struts2 拦截器启动异常
看看你的配置文件、
在看看你导的包

[wangtao20090608]

导包的问题，你把xerces.jar包删了试试。

[人生偌只如初见]

我就只导入了相关的包啊！还是随书光盘里的jar包

[wangtao20090608]

看你的lib下 是否有xerces.jar这个jar包 删了看看行不
