How to create a list from a DefaultModelList so I can marshal to XML using JAXB?

Question

I am very new to this, so please be patient if I don't provide the right information.

I am trying to marshal data to xml using JAXB. The data is in a DefaultListModel. I am trying to move this data into a List that JAXB will recognize. This attempt gives me an StackOverflowError:

    @XmlElement
    Window R = new Window ();
    {
        List r = new ArrayList(); 
        for( int index=0;index<8;index++ ) {
            try {
                r.add(order.elementAt(index));
            } finally {
            }
        }
    }

The DefaultListModel is "order" Can I fix this or am I way off base on how to do this? Any suggestions would be really appreciated.

Answer 1

This is a class that has the list you want to marshal as a property:

@XmlRootElement
@XmlAccessorType(XmlAccessType.PROPERTY)
public class Container {
    private List<Item> order;
    @XmlElement
    public List<Item> getOrder(){
        if( order == null ){
            order = new ArrayList<>();
        }
        return order;
    }
}

You may have to annotate Item (or whatever the class name of your DefaultListModel's element).

The setter for order is typically omitted; one uses

container.getOrder().add( anotherItem );

to build the list.
