serializtion error while invoking method that returns Collection<DataObject>
----------------------------------------------------------------------------
Key: TUSCANY-3499
URL: https://issues.apache.org/jira/browse/TUSCANY-3499
Project: Tuscany
Issue Type: Bug
Components: Java SCA JMS Binding Extension
Affects Versions: Java-SCA-2.0-M2
Environment: Windows
Reporter: Ramanjaneyulu Malisetti
Fix For: Java-SCA-1.6
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
