Tom,

There can be issues getting your .NET WSDL recognized in something
other than a .Net language for certain datatypes. If all you want to
do is transfer an XML document you could perform this quite simply by
sending the file as an array of bytes - example (quickly cobbled
together from an existing app so it may not be 100% syntactically
correct):

public class Document
{
    public byte[] GetXMLDocumentBase64(string fileName)
    {
        public byte[] base64 = new byte[]{ 0x1, 0x2, 0x3, 0x4, 0x5 };
        try
        {
            FileStream fs = new FileStream(fileName,FileMode.Open);
            BinaryReader reader = new BinaryReader(fs);
            reader.BaseStream.Seek(0, SeekOrigin.Begin);
            long lLength = reader.BaseStream.Length;
            int nLength = System.Convert.ToInt32(lLength);
            base64 = reader.ReadBytes(nLength);

            fs.Close();
            reader.Close();
        }
        catch (Exception)
        {
            base64 = new byte[]{ 0x1, 0x2, 0x3, 0x4, 0x5 };
        }

    return base64;
  }
}

This particular service also uses DIME attachments to return documents
but if you are interfacing with Java that is not an option (that I
know of). Finally, if your XML is quite large this may not be very
efficient. I have tested this on document transfers up to 2 mb.

Good luck.
