Thanks for reply Werner !
Actually I did couple of changes to make it work.
One change I did is I am creating an instance (new) of Unmarshaller
now,earlier I was using XMLContext for that.
As I understand from documentation, if mappings are being used then
Marshal/unmarshal should be created using XMLContext. Is there any issue I
will be facing due to creation Unmarshaller instance going forward?
Please advice.
Thanks,
Sam
