Hi,
I managed to narrow down the issue; Unmarshalling throws
NullPointerException whenever there's an attribute set in the xsd:any type
data (in my case when "Version" attribute in "BriefDescriptionX" element is
set, unmarshaller fails); Further I can unmarshall the same message using
JAXB at the client side before calling the service without any problem.
I'm stuck with this issue and any pointers or guidance in resolving the
issue is greatly appreciated.
Thanks,
Nasly
The message (Captured via TCPMon);
<soap:Body xmlns:ns1="http://www.example.org";>
