Answer 1

<interceptor-ref name="fileUpload"></interceptor-ref>
这个定义了吗？

Answer 2

<action name="upload" class="action.UploadAction"> 
            <result name="success">/result.jsp</result>
            <interceptor-ref name="fileUpload"></interceptor-ref>
            <interceptor-ref name="defaultStack"></interceptor-ref>
        </action>
中的
<result name="success">/result.jsp</result>
写成
<result name="success">result.jsp</result>
试试看
