video/x-flv mime-mapping does not for Tomcat 5.5
we are using JBoss4.0.5. For flash video, we added
<mime-mapping>
<extension>flv</extension>
<mime-type>video/x-flv</mime-type>
</mime-mapping>
in tomcat conf/web.xml.
Restarted jboss. When uploading a foo.flv, uploadeFile.getContentType returns "application/octet-stream", not "video/x-flv". Could you please help me?
Thanks,
Dave

André,

You've hit the nail on the head: the browser doesn't "know" the
content-type of the file, so it just uses the generic
"application/octet-stream".
On the server side, you need to figure out what that should be converted
to if you don't like the content-type provided by the client (browser).
You can do this in any servlet like this:
String guessedContentType = getServletContext().getMimeType(filename);
This method should use the mime-type mapping you have set up in
conf/web.xml.

I think Johnny's talking nonsense. But he's gone watch the debate, so I
can probably get away with this.
Seriously, my guess :
I think you are confusing what happens on the way in (browser -> Tomcat)
with what happens on the way out (Tomcat -> browser).
The <mime-mappings> above probably only tell Tomcat what it should put
in the HTTP response headers as "Content-type" when *returning* such a
file to the browser.
On the way in, on the other hand, it is the browser that "guesses" the
file type, and sends this to the server as part of the POST data. The
server then just picks up what the browser says.
If the browser doesn't know what the file is, it will probably in this
case determine that the file is "binary" (not text), and since it does
not know a precise type, it will send it with a type
"application/octet-stream", which is the standard safe Mime type for any
binary file you do not really know the type of.
Try the following : somewhere in your browser or your operating system,
there must be a way to specify that "..for this file type .. do this".
Do that for this file type, and then try to resubmit the same file to
your Tomcat application and see what it says.
If it then works, unfortunately that is only a solution for your own
browser and your own workstation.
In order to determine the file type correctly no matter which browser it
comes from, you probably have to do it in your application.
There exist standard modules/add-ons/libraries/subroutines in most
programming languages, that can make guesses at the mime type of a file.
Unfortunately in Java I personally don't know what it would be.

Hi Dave...
Dave not many clients (I think can do FLV)... so your browser probabaly
doesnt know what it is, so the server cant sent it... my guess...
I think flash files are actually WMV files and inside those files is the FLV
format...
I know on windows we had to jump thru hoops to make FLV's work... just on
their own...
I think you have to convert them to WMV's
Have fun...
