Can JAXB output an ArrayList as comma separated values?

Question

I have something like

@XmlElementWrapper(name="Mylist")
List<Items> myItems = new ArrayList<Items>()

and that comes out like

<Mylist>
   <myItems>item 1</myItems>
   <myItems>item 2</myItems>
   <myItems>item 3</myItems>
</Mylist>

Is it possible to make this come out more like

<Mylist>
   <myItems>item 1, item 2, item 3</myItems>
</Mylist>

Since the data I am after is all just textual anyway?

Answer 1

You can use @XmlList to make it a space separated value.

For a comma separated list you will need to use an XmlAdapter. For more information on XmlAdapter see:
