提示文件解析错误,你要解析的文件格式可能不对..

 

 

<?xml version="1.0" encoding="UTF-8" ?>
<struts>
 <package name="pack.java.file.upload.action" namespace="/" extends="struts-default">
  <action name="FileUploadAction" class="pack.java.file.upload.action.FileUploadAction" >
      <!-- fileUpload Action显式地应用fileUploadStack的拦截器。 -->
      <interceptor-ref name="fileUploadStack"></interceptor-ref>
   <result name="success">/ShowUpload.jsp</result>
  </action>
 </package>
</struts>

 

 

是因为我的struts.xml文件中少加了,如下dtd的验证,.所以导致出错..

加上去就ok. 重启服务器..
