But where I don't agree with your Mr. Matt Benson for the third point. IT IS MANDATORY to set the content type and many real browser WILL NOT DISPLAY anything if it is not set.
In the same way, try to deliver a 1kb (very small file) PDF file to any browser with the Adobe Acrobat PDF plug-in (I doubt that any plugin will work) and you will see that IT WON'T WORK, because the buffer is not full enough to be sent to the client (aka IE, Mozilla, Safari or whatever).

That's wonderful, but
1) You didn't stay on the list 2) I'm not the one with the problem, and 3) Since the original poster is seeing some content, I'm not sure that these servlet suggestions, though worth keeping in mind at all times, will help in this specific situation.
best regards, Matt
