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 <submissionData> element look like that, or be readable xml like the content before it?
