Jaxb json missing brackets for one element array - json

Question

I'm using JAXB/Jersey (1.3) to convert java to json in a REST API.
I read a lot about this problem, I tryed this solution, it work a half:
#XmlRootElement
public class ArrayWrapper
{
public List<String> list = new LinkedList<String>();
}
and my ContextResolver:
#Provider
public class JAXBContextResolver implements ContextResolver<JAXBContext> {
private JAXBContext context;
private Class[] types = {ArrayWrapper.class,Wrapper.class};
public JAXBContextResolver() throws Exception {
MappedBuilder builder = JSONConfiguration.mapped();
builder.arrays("list");
builder.rootUnwrapping(true);
this.context = new JSONJAXBContext(builder.build(), types);
}
ArrayWrapper aw=new ArrayWrapper();
aw.list.add("test");
I get {"list":["test"]} so it works but when I wrapp ArrayWrapper in an other class it don't work:
#XmlRootElement
public class Wrapper
{
public ArrayWrapper aw;
public Wrapper()
{
aw=new ArrayWrapper();
aw.list.add("test");
}
}
new Wrapper();
I get {"aw":{"list":"test"}}
Anyone know how to fix it?

I am not quite sure if you got it working so I am contributing my bit.
I also stumbled upon this issue recently. I found a post in stackoverflow that helped me, but even more helpful was this article (introducing Jackson might help).
I hope this helps you, too. For me it was a matter of 5 minutes to fix the issue.
