File download

[Madhav Bhargava <un...@gmail.com>]

Hi All,

I have a JSP where if a link is clicked then a Save As dialog box is
invoked. If the user chooses to save the file, then on the successful
completion of the file download i need to update a status in the database.
After the status is updated the page from which the Save As dialog box was
invoked has to be refreshed with the new status.

When i invoke a dialog box i use ServletOutputStream and context-disposition
to bring up the dialog box. At the end when i write to the servlet output
stream the response is commited. This means that i will not be able to
automatically refresh the page from which the dialog box was invoked.

Please help me with a solution where in i can capture the status of the
download and make a call to the action to referesh the JSP and the database
with the download status.

Hmm... let me check that out. Will get back to you if this does not work.
The purpose however is to know when the download is complete and to refresh
a JSP.

If i remember well there are special http header that can be used to
tell client the response is split in several part. This is mainly used
when you send a partial response to client (like a html with table
containing 3 rows) and after process advanced you send a more complete
response (like the same html but with table containing 10 rows) and so
on. You could try a 'file then redirect'  construction.  That may be
worth investigations. See HTTP rfc for informations.
