Problems with abstract data types in Axis2
Hi,
We have a class hierarchy exposed through web services, working fine
with Axis1. We are facing an issue while porting it to Axis2. The class
hierarchy looks like:
QRequest --> Abstract class
Project --> Child class deriving from QRequest with some fields
In the web service, I have defined a method
String getStringRequest(ClassParent obj)
Now, from the client side, when I call this method and pass an instance
of "ClassChild", it fails. The stack trace mentions
"InstantiationExceptionConstructorAccessorImpl". My guess is that axis
is trying to instantiate the abstract class here.
I am copying SOAP request and response below. Any help would be greatly
appreciated.
Thanks,
Aman

Can someone give a small hint on how I can try to fix this or move
forward? I am really stuck here.
Thanks,
Aman
