Hi,
I am having trouble un-marshalling a list of objects when the object type in the list has a property which is defined as an abstract class.
Below is how the classes are defined. Have I done this correctly? The server appears to create valid syntax. I have searched the internet for the last couple of days but cannot seem to find a solution. If I switch the transport protocol to XML I do not have this problem, but unfortunately I cannot use this in production.
I have also included a test case which should show the error.
@XmlRootElement(name="diagram")
public class Diagram {
private Shape shape;
public Diagram() {
super();
}
public Diagram(Shape shape) {
super();
this.shape = shape;
}
public Shape getShape() {
return shape;
}
public void setShape(Shape shape) {
this.shape = shape;
}
}
@XmlRootElement
@XmlSeeAlso({Square.class, Circle.class})
public abstract class Shape {
..
}
@XmlRootElement
public class Circle extends Shape {
..
}
Error:
[javax.xml.bind.UnmarshalException: Unable to create an instance of com.diagrams.Shape
I am using the latest jersey server and client jars to do this, running on Jboss 5.1. All other classes are communicated between the client and server seamlessly.
Any help or guidance would be greatly appreciated.
Many thanks,
Peter
