When I take a powerpoint file (something.ppt) and put the file in the root directory, if I try to use IE 6 to see it, it tries to display in the browser window and all it produces is binary garbage. Firefox will show it fine. (I am running JBoss 4.0.3SP1) However, when the file is distributed with a standard Apache server, both IE 6 and Firefox handle it fine. IE 6 opens it IN the browser window.

The only combination that does not seem to work is JBoss + IE6 + Powerpoint. (MS Word docs download and display fine.)

I have tried adding the following lines to web.xml:

<mime-mapping>
ppt
<mime-type>application/vnd.ms-powerpoint</mime-type>
</mime-mapping>

but it still displays as binary garbage in IE6.

Has anyone else encountered this or any ideas on a fix?
