ClassCastException After Upgrade From Axis 1.1 to 1.2.1

["Tootell, James" <jc...@anteon.com>]

All:

I wrote a webservice client a year ago using a combination of Axis 1.1
to handle transmissions and Castor 0.9.7 to handle un/marshalling.  We
recently decided to upgrade to Axis 1.2RC3 and forgo the use of Castor.
I ran WSDL2Java and regenerated all the stub code and supporting classes
and got no compile errors.  At runtime though I consistently get the
following error:

<code>

My call is failing before I even get it to the wire.  I even upgraded
again from 1.2RC3 to 1.2.1 Final thinking maybe it was a bug in Axis but
still no joy.  I've also tried using newer versions of Xerces but to no
avail.  

The service I'm trying to access is a document-style service.  I have
another 1.2.1 client that accesses an RPC-style service just fine.  This
leads me to believe their might be something wrong in the schemas
supporting the document-style service's WSDL but everything validates
and compiles flawlessly.  Does anyone have any ideas why I'm getting
this error?

Also, I tried inspecting the raw SOAP message just prior to calling
_call.invoke() and _call.getMessageContext()'s .getCurrentMessage() and
getRequestMessage() always return null.  Is this normal?  I wouldn't
think it would be.
