Matthew-

It has been my experience that
its because you have non-whitespace characeters before the opening <xml tag
Parser doesnt know how to interpret characters before the opening <xml tag

Dies,
Thanks for the suggestion, but with Xerces-J 2.8.0 I still seem to be having similiar problems. 

The response starts with a FF FE, and here is the stacktrace:

Hello Derek,

I used Xerces-J 2.7.1 and had no problems with a Unicode Byte Order Mark
(BOM) in my UTF-8 and UTF-16 messages using Axis 1.3.

Can you try reproducing the error message with this parser?

Regards,
Dies
