Hi Steve,
I haven't implemented this in struts before; but have in the past built other
java web-apps w/ the downloading of files...
the save-as dialog box is browser dependent (as Richard mentioned) and if a
user has mucked w/ their mime-type settings you may not be able to force the
regular save-as dialog...
(with the types you mentioned pdf, csv, etc this is very likely; also if you
have to support different browsers this may work differently or even be set
differently between them)
If you are in control of your end-user's environment (say a corporate env.)
then this may not be a big deal;
however if you aren't and you really need the save-as dialog in a rigid
fashion; then perhaps putting in an applet is the way to go [this would even
allow you to default to a certain directory regardless of the browser settings
[in a req i have worked on in the past that was very important to my client
since they're users weren't good at remember what directory they save things
in]
the user would have some extra work to accept the signed/self-signed applet on
their first visit; but subsequent visits would be smooth and relatively
consistent
Good luck!
-Mike
