Content is not allowed in prolog

[Scott Hopkins]

I am using Axis in combination with Xerces to connect to a .Net web service.
I get a response correctly but Xerces throws a "Content is not allowed in
prolog" exception when parsing. I believe this is because there is a Byte
Order Mark (BOM) in the response (the ? showing up right before the <?xml
version header). I've seen old messages about a problem with BOMs in UTF-8
files, but have not been able to ascertain if this still a problem. If it
is, is there a work around? Is there another Java parser that will work?


Here's my log from Axis:
