In a servlet 2.3 environment, the default content type is not allowed to
be set on the download.  You must declare it yourself (see below).

Yes.  Yes.

Yes.  You can declare the appropriate content types for your files by
using the <mime-type> declaration like this in your web.xml file:


The other important issue is what your *browser* thinks a particular file
type should be.  Netscape Navigator is usually pretty good about
respecting the "Content-Type" header sent by the server, while IE tends to
make its own assumptions about the file type, no matter what yo do on the
server side.
