Thanks Davanum,
That resolved the issue on the request side, but unfortunately what looks
(to me?!) like a similar error now occurs when the server is serializing its
response.
(This is the same client and server, generated successfully using
wsdl2java).

This happens if my implementation of the service skeleton interface sets ANY
of the fields in the abcType object (which is itself a member of the
abcElementDocument object returned by the service method).
Have you seen this before?
Many Thanks,
