Mac/stream problem

Jan Agermose

I have this webapplication, that lets You pick a list of pictures to
download. At the en you klik on a link that says download and this url is
mapped to a servlet. The servlet looks up the pictures you selected and
prepares to send the pictures as a zip fil to you. This is done by setting
the response content type to "application/zip" and wrapping the response
stream to a zipoutputstream and then writing entries to the zipoutputstream.

This works very good when ever the client browser is a windows/IE, but
whenever the browser reads mac/IE the download fails.

The top of the exception stacktrace:
java.net.SocketException: Connection reset

Any hints/ideas?

It looks like your mac/IE client is closing the socket. Does it not
know how to handle application/zip? What does the client do? Perhaps
changing the Content-Disposition in the http header may help? How does
it work with Mozilla?

I've had contact to 3 different macusers and the results are all different
(on different browsers and OS9/ OSX), ranging from not getting any data to
getting the 25Mb zip file and not being able to open it, and then also one
success....

I have no idea on what to do here... and im somewhat dependent on being able
to serve mac users as a lot of publishing/imageing is done on mac' :-|

On your hint I found this:

res.setContentType("application/x-download");
res.setHeader("Content-Disposition", "attachment; filename=" + filename);

I will give it a try...
