John, we have a similar process where by we allow a customer to download a file. Instead of the Struts handling the actual downloading, we direct the user to the informational page for the file. That page contains either javascript or a meta-refresh tag which redirects the request to the file to be downloaded. If found, the browser does the rest (displayes file save dialog box). The user can then download the file while on the informational page for that file. When they are done downloading the file, the dialog box goes away leaving them on that file's informational page.
