It should be mentioned that IE as a browser will store the downloaded
file on disk in its cache system ("temporary internet files") before it
opens it. This is the case regardless of content disposition. Other
browsers will behave similar.
If it is important that the file is never resident on disc, this may be
important.
If it is only important to unburden the user from the decision and
effort to store the file somewhere and reopen it manually, the solution
given should be sufficient.
Another possible way may be utilizing things like DDE (still alive or
already dead?) or OLE or whatever MS uses for IPC currently. But then
the Java application will have to make use of these Windows-specific
features which may be quite untrivial. ;-)
