2、错误原因

     从报错可知，不能找到Action或结果，servlet配置路径错误

 <servlet>
     <servlet-name>UploadServlet</servlet-name>
     <servlet-class>com.you.mail.servlet.UploadServlet</servlet-class>
 </servlet>

 <servlet-mapping>
     <servlet-name>UploadServlet</servlet-name>
     <url-pattern>/servlet/UploadServlet</url-pattern>
 </servlet-mapping>  

3、解决办法

     修改servlet配置路径，或者修改JSP放置路径

 <servlet>
     <servlet-name>UploadServlet</servlet-name>
     <servlet-class>com.you.mail.servlet.UploadServlet</servlet-class>
 </servlet>
 
 <servlet-mapping>
     <servlet-name>UploadServlet</servlet-name>
     <url-pattern>/uploadServlet</url-pattern>
 </servlet-mapping>
