JAXB how to marshall ArrayList>

Question

I got an attribute like this

private ArrayList<ArrayList<Vector3D>>    trajectories = new ArrayList<ArrayList<Vector3D>>();

Vector3D is a simple container for 3 double values. How do I marshall this properly with JAXB? I only get elements in the XML-File.

Have a look at this, perhaps it's related: http://stackoverflow.com/questions/8254948/soap-response-wrongly-deserializing-as-null-in-cxf-simple-frontend-aegis-dat/9921501#9921501 — Anders R. Bystrup, Nov 13 '12 at 10:21
Also, I suggest you use the interfaces rather than concrete types: `private List> trajectories = new ArrayList>()` — Anders R. Bystrup, Nov 13 '12 at 10:23

1) Use

private ArrayList<ListOfVectors>    trajectories = new ArrayList<ListOfVectors>();

instead of

private ArrayList<ArrayList<Vector3D>>    trajectories = new ArrayList<ArrayList<Vector3D>>();

where ListOfVectors is

@XmlAccessorType(XmlAccessType.FIELD)
public class ListOfVectors 
{
   ArrayList<Vector3D> list = new ArrayList<Vector3D>();
}
