I have code like this:

```
import org.codehaus.jackson.map.*;

public class MyPojo {
    int id;
    public int getId()
    { return this.id; }

    public void setId(int id)
    { this.id = id; }

    public static void main(String[] args) throws Exception {
        MyPojo mp = new MyPojo();
        mp.setId(4);
        ObjectMapper mapper = new ObjectMapper();
        mapper.configure(SerializationConfig.Feature.WRAP_ROOT_VALUE, true);        
        System.out.println(mapper.writeValueAsString(mp));
    }
}

```

It works expected:

```
{"MyPojo":{"id":4}}

```

But I want to customize that name. I am not able to mark `MyPojo` with `@JsonTypeInfo` becausee i take this class from library.

Is there way to do it in jackson?
