I'm using an AJAX (POST) call to a servlet which streams back a Microsoft Word document. I arrives back safely, but I don't know how to spawn a new window (window.open) and populate it with the contents of that Word document. Any thoughts?

Hi David,
What about opening a new window first and using javascript in the new window to do a form submit to get the server side to stream your application data?

My 2 cents.

Thanks. I had thought of that and it's what I'll do if all else fails.

I just think there has to be a way of passing back the binary data to the window.

From the parent window you can open a new window and obtain the reference to document of the new window


This should work

You should just call the serverside page directly in the window.open or an in iframe. Do not do an Ajax call since JavaScript can not handle binary data.

Agreed, doing some more digging it does appear AJAX just isn't fitted for fetching binary data.

However, how can you specify a POST method using the techniques you suggest?

Eric, was there something different I was meant to see in that link? It looks like the "hidden form submitted using Javascript" technique discussed earlier:

It showed you how to post the form to another window. Isn't that what you were asking?

Sure, but I can't see it suggesting a technique that hasn't been discussed above, that's all.
