RE: Response and file downloads
Justin is of course completely correct. When you submit a form to the server, you are getting a response back. That response could be in a number of forms, but there's no such thing as creating a second response on the server and sending back both. If you want to avoid client-side scripting (which is how soemthing like this would typically be done) what you can do is return your form page simply with a link to the file to download. This link would in fact be a call to your server-side process that will push the file through THAT response. Be sure to set the content-disposition headers on the response and you'll get a Save As dialog on the client WITHOUT overwriting what's in their browser. As an alternative to the link, call a Javascript function on the pages' onLoad() event that does the same thing as clicking the link would. Or, if you really don't want to use the scripting, do it with a meta redirect (or refresh, I forget off-hand) to do the same thing. The pertinent point is that the content-disposition header will result in the Save-As dialog rather than overwriting what's on the browser already. -- Frank W.

RE: Response and file downloads
As the other poster correctly stated HTTP is a single request/response protocol -- emphasis on protocol. Once you send the headers and response to a browser from a server, you can't send another one. This is not a Tomcat issue.

Re: Response and file downloads
I know there is only a single response, thats why I want to create a new one :) Then you need to have the client create another request. How do other sites generate files on the fly (take it out of a database, or a report just run), on form submit, and send them down the line and not run into this problem? Which other sites? Can you point to one that we'd all be able to see? Often with a sample site, it's easier to tell you how they did it. I've seen some sites that simply return a thank you or other updated page. It often contains a link to the download, with a message that says a download should trigger automatically within a few seconds. In this scenario, I believe they are returning a page with a link that would cause the file to be downloaded (so the user could click it if the download didn't start) along with an HTML HEAD refresh tag like: meta http-equiv=Refresh content=1;URL=/path/to/download/file Such a refresh tag will cause the browser to wait a second (in this case 1 second because 1 is before the semicolon) and then issue a GET on the URL provided. Since the URL is for a file download, it appears that you've both triggered a download AND returned a page, but in fact, you just returned a page, and that page triggered the auto-GET that triggers the download.

Re: Response and file downloads
Just an FYI: I was unable to get the body onLoad() to work properly on both IE5 and Mozilla - forget exactly why but it was supposed to work! Anyway, I instead used an IFRAME (internal frame) which I added to my forms' output stream(the same form the user just clicked submit() on - essentially a reload with new status information updated and a tad-bit-o-extra-output). The little-bit-o-code is below: iframe name=thisIFRAME id=thisIFRAME src=get_doc?key_id=1668 frameBorder=0 width=0 scrolling=no height=0/iframe This creates a hidden(I don't want to argue the metaphysical side of this) window which in effect 'clicks' on the link I created.

Dude, you need to get out more :-) IFRAME is part of the HTML 4.0 spec: http://www.w3.org/TR/html4/present/frames.html#edef-IFRAME Old news. It works fine in Moz, Opera, Konqueror...

Getting out hasn't happened much for about eight years now :) IFRAME is part of the HTML 4.0 spec: http://www.w3.org/TR/html4/present/frames.html#edef-IFRAME Cool, I didn't realize that. Maybe it was just that support for it was not universal until relatively recently. The last time I did any non-IE development frankly was about 3-4 years ago, obviously much could have changed since then. And you can use OBJECT to include anything -- text files, HTML files, images, whatever; if it's a browser-native format, it'll just be displayed. Something like this: object type=text/html data=alert-js.html height=100px width=300px /object :: will include the page referenced as data. That's definitely cool too, I never would have thought to even try it. I assume an object is available through DOM... does it have a src attribute? You know what I'm getting at: dynamic changing of the content. If that's possible, any idea how universal that would be?

Re: Response and file downloads
Yeah, even though I don't do much non-IE work these days, the other browsers are at worst comparable (and many would say have far exceeded IE). If you stick to standards-compliant code, there tends to be not much difficulty writing cross-browser code these days. I think there's still enough difference in how things are rendered to make it unpleasant, but it's not nearly as difficult as it used to be. -- Frank W.

I'm getting the impression that the other browsers have caught up but I refuse to develop for them unless made to. Questions: Have the other browsers caught up with ease and power of their scripting? Do any of them have an XMLHTTP equivalent? Do they share a common DOM? I hate writing cross browser code. Supporting multiple browsers is like having to test and write every application in Java, VB, and C. Chad -Original Message- From: Frank W.

I do know for sure that they were originally an IE-only extension, so if Mozilla does support it, it represents a very rare case of Microsoft leading the pack :) I'm not sure about the object tag idea... I've never seen it used that way but that certainly doesn't mean it won't work. My understanding is that it embeds content in a page that is recognized by one plug-in or another... I suspect it wouldn't help in this case, but I could be wrong.

RE: Response and file downloads
-Original Message- From: Justin Ruthenbeck It seems like what you want is for a user to fill out a form, click submit, then be presented with a new, fresh, form again ... with the file download on the side. If you have determined that you absolutely want this behavior (it's atypical, so doing it won't be particularly robust), consider programmatically opening another browser window on form submit from which the download will happen ... and reload your form in your main browser window. This will, of course, subject you to any headaches associated with javascipt window opening. Justin, since I want a basic download, I'd be interested in what you consider typical please? I need to offer the user a list of files (I'd thought of a form or list of links) They select one, then download it. What's the tomcat way please? regards DaveP -- DISCLAIMER: NOTICE: The information contained in this email and any attachments is confidential and may be privileged.
