Abstract class as input Parameter in WebService

Abstract class as input Parameter in WebService

I've a problem to use abstract class in a Web Service like WebMethod input
parameter. I'm using jboss-eap-5.0.0.GA.
Parent class
@XmlSeeAlso({ ChildA.class, ChildB.class })
public abstract class Parent {
protected String parentName;
}
ChildA class
@XmlRootElement(name = "childA")
public class ChildA extends Parent{
private String strChildA;
}
ChildB class
@XmlRootElement(name = "childB")
public class ChildB extends Parent{
private String strChildB;
}
Service class
@WebService(name = "ParentService", serviceName = "ParentService")
@SOAPBinding(style = SOAPBinding.Style.DOCUMENT, use =
SOAPBinding.Use.LITERAL,
parameterStyle = SOAPBinding.ParameterStyle.WRAPPED)
public class ParentService {
@WebMethod
@WebResult(name = "parentResponse")
public Parent process(@WebParam(name = "parentRequest") Parent parent) {
System.out.println("process calling ------------");
return parent;
}
}

Client class
public class Client {
public static void main(String... strings) {
ParentService_Service impService = new ParentService_Service();
ParentService service = (ParentService)
impService.getParentServicePort();
ChildA childA = new ChildA();
childA.setStrChildA("ABC");
System.out.println(service.process(childA));
}
}
When I start this client i've this Exception server side:
