Hi,
I have SCA service bound to JMS binding and using SDO
DataBinding. I am encountering the following exception while client is
invoking a method that returns Collection<DataObject>. Out of
curiosity, I have added another method that returns Collection<String>,
this method is successfully returning, but, to my surprise, client got
list only with size 1 instead of actual size of the arraylist returned
by the service implementation.
I attached source at [1] for your reference.
What is the wrong with serialization, why below exception shows JAXB
databinding instead of SDO databinding?
Why client could not receive object as it is returned by service in case
of Collection<String>?
