Simple (?) question concerning JSON root-Object

[hairman]

Hi!
I didn't find an example and don't know how to search for the solution.

These annotations "generate" the following JSON:
@XmlRootElement
public class Object {
String key;
...
}

{ "object" :
       {
       "key" : "value"
       }
}


But how do I annotate the class to produce such a JSON:
{
  "key" : "value"
}

[Wolfgang Laun-2]

Try this:

@XmlValue
  String key;

Hi!
Perhaps my problem doesn't directly refer to JAXB... I use JAXB annotations together with the RESTEasy Client framework.
With a bean like this:

@XmlRootElement(name = "simplebean")
public class SimpleBean {
    String key;
  ....
    @XmlValue
    public String getKey() {
        return key;
    }
I understandably get the following exception:
[javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"key"). Expected elements are <{}simplebean>]

Without @XmlRootElement(name = "simplebean") REStEasy won't find a MessageBodyReader to serialize/deserialize the bean.

To me,  the JSON { "key" : "value" } suggests that the object is called "key"; so probably this ought to be specified instead of simplebean as value of @XmlRootElement's name.

Yes, you're right!
But for the following JSON there no longer is a "single" object name, to me:
 {
    "key" : "value",
    "key2" : "value2"
 }

I tried  "@XmlValue String[] values" but this produces {"key":"value value2"}

Please keep in mind that JAXB and it's cousins aren't capable of expressing all of Java in XML, and vice versa. JSON isn't a 100% equivalent for XML, so there may be incompatibilities which cannot be blamed on any of these systems.
