SimpleDeserializer encountered a child element

[Sloan Seaman]

I'm using Axis to connect to M.S.'s XML/A and I can connect fine but Axis
keeps blowing up with the response that XML/A is returning.

Looking at what is happening I can see that XML/A is returning well
formatted XML (show below) but for some reason my code keeps causing a:
[java] org.xml.sax.SAXException: SimpleDeserializer encountered a child
element, which is NOT expected, in something it was trying to deserialize.
error.

I've been at this for over two days now.  Can someone please help me out?

Thanks!
