提示很清楚
Caused by: java.lang.ClassNotFoundException: org.apache.commons.fileupload.RequestContext
原因：少导了一个包 commons-fileupload-1.2.1.jar另外：
<filter-class> LZ采用的是2.0的配置
2.1则开始采用新的过滤器 org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter试试看，应该是以上原因造成
麻烦请教楼上，Struts各版本对基础JAR包的依赖是什么？有什么不同呢？
少个包 commos-fileupload  添加进去就行了
这个问题，LZ最好能自己找以便加深影响，因为遇到异常时程序员每天都要面对的，如何去解决，到哪里找答案才是最重要的。总是找别人帮助解决，LZ日后会感觉很累的!!!
如果你是用maven管理工程的话，那你可以很清楚明了的知道，各个jar之间的依赖关系
