deserialize a json array using xstream

Question

There is a lot information at stackoverflow about how to deserialize a json array using Gson.

But how can I do the same using XStream with jettison?

Here is json:

{"entity":[{"id":"1", "name":"aaa"}, {"id":"2", "name":"bbb"}]}

Here is XStream code how I try to parse it:

XStream xstream = new XStream(new JettisonMappedXmlDriver());
xstream.alias("entity", Entity[].class);
return (Entity[])xstream.fromXML(jsonString);

I have following exception:

com.thoughtworks.xstream.converters.ConversionException: id : id

With array I cannot get it running, but with a list:

Java:

package de.mosst.spielwiese;

import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;

import org.junit.Test;

import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.annotations.XStreamAlias;
import com.thoughtworks.xstream.io.json.JettisonMappedXmlDriver;

import lombok.Data;

public class XStreamDeserializeJsonWithJettison {

    @Test
    @SuppressWarnings("unchecked")
    public void smokeTest() {
        InputStream file = XStreamDeserializeJsonWithJettison.class.getResourceAsStream("XStreamDeserializeJsonWithJettison.json");
        XStream xStream = new XStream(new JettisonMappedXmlDriver());
        xStream.processAnnotations(Entity.class);

        List<Entity> entities = (List<Entity>) xStream.fromXML(file);
        System.out.println(entities);
    }

    @Data
    @lombok.AllArgsConstructor
    @XStreamAlias("entity")
    class Entity {
        String id;
        String name;
    }
}

XML:

{
    "list": [
        {
            "entity": [
                {
                    "id": 1,
                    "name": "odin"
                },
                {
                    "id": 2,
                    "name": "dwa"
                }
            ]
        }
    ]
}
