[xfire-dev] service method with an abstract class as parameter?

[Bob_A_Bueckers]

Is this possible? 

What I would like to do is have one method that can take either of the 
concrete implementations(Bclass, Cclass). When I attempt to do this it 
appears that the WSDL generates fine, but when I test the service method 
it appears that XFire tries to instantiate the abstract 
class(AbstractClassA) rather than the concrete class that is passed 
in(Bclass , or Cclass). Am I missing something here? 


TestServiceClass
        loadData(AbstractClassA data);


AbstractClassA
        Bclass extends AbstractClassA
        Cclass extends AbstractClassA



Thanks in advance!

Bob
