Subject: AW: Abstract classes and
inheritance
Ok,
finally I solved this issue.
First I want to mention that I'm using Axis
1.2.1
The
major problem was, that while creating the stub, the inheriting class had not
been produced.
(It
was there, but only because I have two services in the same stub (or two
stubs in the same package) and it was produced by the other one, which I
haven't used, yet. That's why I didn't recognize the
problem.)
But
there was definiteley no entry in the XXXSoapBindingStub.java, so
the stub didn't know the class.
On
the other hand, the abstract class had been produced.
So
why did that happen?
I
found out the following:
In
the service I did not use the the inheriting class in a method and I only used
the abstract one as an array, like:
Message[] getMessage()
In
this case, the inheriting class is not generated. It's different if you
mention the abstract class somewhere in the service like
this:
Message getMessage()
Then
the inheriting class will be generated, too, and there
will definiteley be an entry in the
XXXSoapBindingStub.java
Now
everything works fine! :-)
Well, I'm a newbie in Webservices and maybe I did
something wrong that's supposed to be very simple,
but
perhaps this helps other novices not to fall into the same
trap.

Hi,
I'm sorry, I have not got the hang of it, yet.
Markus
Hi,
do you solved your problem? Because I have
got a similar problem, and I don't know how to solve it. If you selve it,
write me please.
Thank you
Ales

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
