problem finding external entities via HTTP

[Ko...@ubsw.com]

I'm having a problem parsing external entity references in some xml 
files that I am rendering using Cocoon - I suspect that this is more of 
a Xerces issue than a Cocoon one.

The problem arises when I have entity references that use HTTP URLs. 
Normal static URLs are fine, but I need to retrieve some entities using 
a servlet that I have written which connects to a document managment 
system, and this fails. In short, the following entity references using 
my servlet fails:

<!ENTITY E18467 SYSTEM 
"http://myserver/dm-demo/servlet/dmserve?dmdoc=0900270f800430&docDesc=id
">

but the following reference where the required file is located on my 
webserver's filesystem is fine:

<!ENTITY E18467 SYSTEM "http://myserver/dm-demo/entity-file>

The error reported by Cocoon is

Is this a bug, or am I just doing something stupid?! I'm really stuck 
on this one, so any help is much appreciated!

Cheers,

Kosh
