Hi,
that's something that is not really achievable. Have a look at the
following code fragment:
SearchPubsResponse entity =
(SearchPubsResponse) unmarshaller.unmarshal(new
InputSource(getClass().getResource(SAMPLE_FILE).toExternalForm()));
assertNotNull (entity);
assertNotNull(entity.getPublicationList());
assertFalse(entity.getPublicationList().isEmpty());
assertEquals(2, entity.getPublicationList().size());
As you can see, I am instructing Castor XML to unmarshal an instance of
SearchPubsresponse. Subsequently, I am accessing the collection of
PublicationImages via the collection property of that class.
I hope this helps.
