I'm having this issue when attempting to serialize an object that exists
within another object (complex data type). Here are my classes:
The containing class:
@XmlRootElement(name = "result")
@XmlAccessorType(XmlAccessType.NONE)
@XmlSeeAlso({TripVO.class}
public class ResultVO {
@XmlElement
private String id;
@XmlElement
private boolean success;
@XmlElement
private String[] messages;
@XmlElement
private Object data;
}
The data element is the one which is having issues. In my test case, the
data element is an instance of the following class:
@XmlRootElement(name = "trip")
@XmlAccessorType(XmlAccessType.NONE)
public class TripVO {
// Set by the client service
@XmlElement
private String id;
@XmlElement
private String name;
@XmlElement
private String tripType;
@XmlElement
private String userName;
@XmlElement
private int rank;
private ArrayList<String> tags;
private String desc;
private String imageUrl;
private String startAddress;
private int duration;
@XmlElement
private String startDate;
private List<TripPointVO> points;
public TripVO() {}
}
When I attempt to serialize ResultVO I get the exception:
java.lang.IllegalStateException: Invalid JSON namespace:
http://www.w3.org/2001/XMLSchema-instance
If I leave out the @XmlSeeAlso annotation, I get:
javax.xml.bind.JAXBException: class com.randmcnally.trip.common.vo.TripVO
nor any of its super class is known to this context.
I am not using any explicitly defined namespaces, as this is a solely
JSON-based REST interface. I want the ResultVO class to act as an envelope
for my other classes (i.e. every response will have its attributes, along
with a sub-object called data with the specific information). Does anyone
have any idea how I can fix this?
