Subject: Abstract classes and
inheritance
Hello everyone,
I got stuck with a problem concerning abstract
classes.
I've got an abstract class called
'Message' and a concrete one called 'DefaultMessage' which does inherit
'Message'.
I've got a method getMessages()
of return type Message[].
On the server
implementation the method returns an array of type 'Message', but each member
references to an instance of 'DefaultMessage'.
On the client side I get an array with proper
length but null values. If I do not declare 'Message' as abstract it works
only if 'DefaultMessage' does not contain any bean members.
The 'stubt version' of getMessages() returns
instances of 'Message', not of 'DefaultMessage' which should be the
case.
If I add a bean member (like
'defaultValue') to 'DefaultMessage' I get an Exception from the stub:
org.xml.sax.SAXException: Invalid element in
test.messenger.service.Message - defaultValue
org.apache.axis.AxisFault.makeFault(AxisFault.java:101)
org.apache.axis.client.Call.invoke(Call.java:2451)
org.apache.axis.client.Call.invoke(Call.java:2347)
org.apache.axis.client.Call.invoke(Call.java:1804)
test.messenger.service.MessengerUserSoapBindingStub.getActiveMessages(MessengerUserSoapBindingStub.java:362)
test.messenger.gui.model.ServiceManager.getNewMessages(ServiceManager.java:57)
....
The SOAP message looks ok.
It contains 'defaultValue' and defines the array elements as
'DefaultMessage'.
Any ideas?
Thanks a lot,
Markus
