I assume your example here is using the default Jettison provider, then?
In my current example, "features" is just a list of Strings, but an
example of a list of non-primitives is also worth exploring.
I believe what you're saying in this example is that I need to set
"serializeAsArray" to true, but leave "arrayKeys" as an empty list
(which makes me wonder what that property actually does).
For reference, here is my current Item class:
@XmlRootElement(name = "Item")
public class Item {
private String id;
private String title;
private String description;
private List<String> features = new ArrayList<String>();
// This combination produces
"<features><feature>val</feature></features>".
@XmlElementWrapper(name = "features")
@XmlElement(name = "feature")
public List<String> getFeatures() { return features; }
}

We'll see. If I still have issues with using Jettison, I'll try to move
forward with using Jackson.
Thanks for your help.
