Here comes my unhelpful response for the day...

I've got the thing to work returning null as my forward. That leaves a couple
of questions though.
1) Does struts write anything to the response before calling you action class?
I don't think so.
2) Does calling flush() on the response output stream cause the response to be
sent? I kind of think it doesn't, but what exactly does flush() do in this
instance.
I don't think so.
AND
3) Does struts close the response output stream for me?
I don't think so.
:)
On the first point, I very much doubt it... some headers may get set,
but I don't think anything gets written outside your Action.
On the second point, I looked at some code I wrote that does this and
some of it calls flush(), some of it doesn't, and both seem to work. I
think it's probably a better idea to call it yourself to be safe, but it
doesn't seem to matter.
On the first point, I'm almost certain Struts wouldn't do that, but your
container certainly may (and perhaps correctly should).

Subject: Re: returning a non-html file as response
Hi,If you are writing the response from an Action (which yes, you can do asyou describe), you should return null from execute(). This indicates toStruts that you have taken responsibility for rendering the response andno forward should take place, the response should simply be returned as itexists at that point.-- Frank W.
