> Hi All:
> I can post the File to my action and store them in database using tag:
> <s:file name="upload" />.
> According to Struts 2 , the "name" must be assigned as "upload". However,
> why not the "name" are assigned to different value? just like it :
> <s:file name="upload1" />
> <s:file name="upload2" />
> <s:file name="upload3"/>
>
> If so, we can very clear that which input tag submit the upload file in
> the JSP. Because after upload file is submitted, the upload file will be put
> into a list, you cannot find which tag submit the upload file.
>
> I just think there is something inconvenient.
> Who can give me some advices ?
