Hi Andrei,
Appreciate your reply.
Good point... you are correct, there is nothing about CXF in my classpath (see
below). I suspect I should replace some or all of the Spring jars with CXF
jars. Dumb question is there any advantage to running the CXF implementation
over the Java jaxws implementation, like CXF is faster? I could be totally
wrong but I don't think my casting exception is related to the jaxws
implementation.
My feeling now is that I'm starting with the wrong approach, i.e., right from
the WSDL definition I'm building from. As you can see in the code snippet
below all parameters are mode.INOUT. In my mind this doesn't make sense for an
asynchronous web service client, i.e., they should be IN only hence the Holder
class won't be involved at least not for input parameters.

Hi David,
I do not see CXF in your stack trace. Are you sure that you have CXF jars in
classpath?
Actually it looks that you use default JDK jaxws implementation.
Regards,
Andrei.
