content not allowed in prolog exception

I am trying to send xml to a java-based web service given to me by a thrid party via a c#.NET application, and I get the "org.xml.sax.SAXParseException: Content is not allowed in prolog" error.

I have verified the xml against the schema, and I passed the memorystream I am using to hold the xml to an .xml file, then opened the file with a hex editor to make sure that there were no undesired characters in the prolog, and there are none. When opened, the first characters in the file are

<?xml version="1.0" encoding="utf-8"?>

The class I was given to use to send the xml data to the web service accepts a byte array. I figure that creating the xml using an XmlTextWriter to a utf-8 encoded memorystream, then sending the contents of the stream to a byte array is the most direct method.

I have done a lot of research and tried all the possbilities around this issue that I could find, but nothing works. Could someone please help? Thanks in advance.

By the way, here is a portion of what the web service returns to me. In the payload of the SOAP message, should the data after the element look like that, or be readable xml like the content before it?
