Jettison is uncapable of deserializing sequences containing something like
"@name":"foo".
So if you can change @XmlAttribute to @XmlElement then it would help.
Now, the other Jettison issue in this example in that it is only capable of
dealing with this sequence only if 'd.' is appended to the root 'definition'
element but not to 'structure'. So if you can update the annotations such
that only the root 'DataDefinition' class has the namespace or no namespace
at all then it would help too.
So you should end up with a sequence like this one :
{"definition": {"repeating":"false","index":"0","name":"Credit Line Increase
Data",
"structure":[{"repeating":"false","index":"2","name":"CreditLineIncConversation",
"symbolic":[
{"index":"0","name":"ReasonForIncrease"},
{"index":"4","name":"TermConds"}
]
}]
}
}
(note that the structure is an array [] now).
There're a lot of preconditions there. in 2.2.4-SNAPSHOT it is possible to
tell a JSONProvider to drop namespaces. More customization will be coming in
later on to deal with the attributes issue and to ensure sequences can be
deserialized into JAXB beans with XmlRootElement containing namespaces.
