Such an approach should be fine, I am afraid I dont have time to debug
your code - but there is no reason why you shouldnt be able to read
from REST in Java using a URLConnection.

Personally I would never rely on URLConnection.getContentLength() -
that might well be your problem. You may also find it easier to use
the Apache Commons HTTPClient for this sorta thing, I know that I do!

No the mimetype is always set by eXist reading what was stored when
the file was stored and setting it appropriately on the http response.

I think your code should work - there are probably just some bugs in
there that you need to iron out!
