Struts Download Action
Hi All,
I'm developing a web application based on Struts. In this, one of the
features to be included is , to download a file, when the user clicks on
the link in the JSP page.
Also, when the user clicks on the link, the Save/Open dialog box should
appear.
If nyone has used the DownloadAction provided by Struts OR any other
solution , please help.
Thanks

Thanks Martin, that's precisely the page I was referring to. I couldn't
get out to it a few minutes ago... looks like my network hiccuped
momentarily.

I can't seem to access the Wiki right now to give you an exact link, but
if you search for DownloadAction there, you will find a page that
includes a sample app I wrote to demonstrate using the action. It shows
downloading a file on the file system and also from a database, if that
is relevant for your use case. The page gives a good overview of using
it besides.
I have used this action myself, and well as a straight servlet
approach... I'm not sure either is better than the other, or easier, but
I would go with the DownloadAction since your app is already
Struts-based just to "keep it all in one place".

Re: Struts Download Action
Posted by Larry Meadors <la...@gmail.com>.
I have used a straight servlet to download a blob from a database
using a URL like this:
http://someserver/documents/123/file.pdf
I did it this way instead of using struts because IE is a pile of crap. :-)
In this URL, the /123/ is the record's id, and file.pdf is the
suggested extension for the browser, which just thinks that is it a
static file.
If you're interested, I can send you the source for the servlet - it's
only a few lines of code.

It actually does say right at the top that it was added in 1.2.6. If
you think that should be expanded upon, feel perfectly free to add to
the page... that's the beauty of a Wiki after all :)

Thanks , I got it working with Download Action. But one thing missing in the
tutorial was that there was no mention that this Download Action was
available post struts 1.2.6. Would be great if this is included.
Thanks all.

That's good info... might be worth adding to the Wiki (hint-hint :) )
Also, I don't think there is anything to stop you from using the
DownloadAction in Struts prior to 1.2.6 when, IIRC, it was added. I
could be wrong, but I don't remember anything that would make that not work.

Re: Struts Download Action
Posted by Sudhaker Raj <su...@gmail.com>.
http://wiki.apache.org/struts/StrutsFileDownload is great, but in case
you are using struts older than 1.2.6...
You just return null from execute method, framework will not do any
thing further. Now it is your responsibility to read the target file,
set correct content-type and then write the content on
response.getOutputStream();
Sample code:
public class ResponseWriterAction extends Action {
public ActionForward execute( ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
response.setContentType("application/zip");
// Set the content disposition
// To download
response.setHeader("Content-disposition",
"attachment; filename=" + fileName);
// To open up in the browser
// response.setHeader("Content-disposition",
// "inline; filename=" + fileName);
byte[] buff = new byte[4096]; // 4KB
OutputStream out = response.getOutputStream();
while (moreContent) {
// read content in buff byte[]
out.write(buff);
}
out.close();
return null;
}
}
Hope this helps.
Cheers,
Sudhaker
