Forwarding and File Download problem
This is an old one but I have scoured the archives and not seen a
definitive answer to my problem.
I am downloading a file via an Action class and want to refresh the Page
display after the download completes. Now the action which should be
forwarded to is not being executed. I have even tried to forward to a JSP
rather than Action class but nothing seems to work.
This has been reported on more than one occasion eg:
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=struts-user@jakarta.apache.org&msgId=154587
Never found a definitive answer.
Also the dialog box that IE pops up says that "you are downloading the
file: <action class name> from localhost". This is misleading as the
actual dialog box that is next presented correctly names the output file
name that I have set up. How can I change the name of the file on the first
dialog box ?
TIA
Eddie

The only way I know of to suggest a filename to a browser is to output
the header
Content-disposition: attachment; filename=<filename>
However I think this only applies when you're dumping the file directly
after the header. Is this what you want to do?

Eddie,
The reference you refer to is for upload, so I am a bit confused as you
talk about download.
I assume you do mean download so:
To change the name that you are downloading you need to have a mapping to
your download servlet so that you can use a request path like
http://....../download/myFile.jpg then the browser dialog will show
myFile.jpg. I am not sure how you'd acheive this with an Action Class, I'd
look around creating a new mapping something like this:
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>/download/*</url-pattern>
</servlet-mapping>
Before anyone shoots me down, I am not at all sure this will work as it
stands, but it is a starting point.
As far as the redirection after the download is concerned, you have a
problem in that the browser is requesting the page and then doing nothing
else. That's the way HTTP works :-(
You could experiment with using a refresh header tag in the page from which
you launch the download, so that it refreshes every 5 seconds or so.
Hope the (slightly vague) ideas help.
Mike
