Description
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 service side implementation.
Here, I attached source 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>?
Serverside
