I don't think you can pass or return an interface type across
the Web Service binding, only a class type.
This is a rather nasty limitation. I believe there is some deep
JAXB magic ("factory" annotations) that could work around this
limitation, but I haven't got far enough into this to know how
to use it or whether it currently works in Tuscany.

hello,
this is an example that shows the problem.
listSalePointCodesOA and listSalePointCodesIA return an array and works
well, but listSalePointCodes return a List and have the commented
problems.They are defined in.Services and implemented in
ServicesImplementation.
Runner is the class that start the application.
The web services are published in http://localhost:8887/Services?wsdl.
thanks,

hello,
I have a problem when I expose a service with ws binding.
When I want to return a collection of elements, if I use a List type the
web
service invocation return only 2 elements of the list (when I use
LinkedList) or an empty collection (when I use Array).
I suppose the problem is in the implementation of the web service with
axis2. It's that right? How can I change the configuration of axis to
return
all the elements of the List?
thanks,
Mariano
Hi Mariano
Can you provide a example of this problem. If you can't provide the whole
thing then the service interface that you are using would be good (or a
sample interface that has the same types)? It sounds like it could be
something wrong with either the way interface definitions are being
generated or in the way that data is transformed and marshalled across the
wire. The easiest thing is if you can provide an example that doesn't work
that can be debugged.
Thanks
Simon
