Display specific element from list via REST

I have some problems with displaying specific element from ArrayList vai REST. When I display all elements from list is ok, but when I try to display specific element (e.g. first from the list), I have error:

org.glassfish.jersey.message.internal.WriterInterceptorExecutor$TerminalWriterInterceptor aroundWriteTo SEVERE: MessageBodyWriter not found for media type=text/xml, type=class .......Model, genericType=class .....Model.

I tried to set @XmlRootElement in model, but than I can not display anything. How can I change my code to fix this problem?



Model:

public class Model {
    private String nin;
    private String surname;
    private String name;

    public Model(String nin, String surname, String name) {
        super();
        this.nin = nin;
        this.surname = surname;
        this.name = name;
    }
   //getters & setters
}

List of persons:

@XmlRootElement(name = "persons")
public class ListOfPersons {

    List<Model> personList = new ArrayList<Model>();

    ListOfPersons(){
        personList.add(new Model("92", "K", "S"));
        personList.add(new Model("94", "C", "O"));
    }

    public List<Model> getList(){
        return personList;
    }

    public void setList(List<Model> list){
        this.personList=list;
    }
}

Rescource:

@Path("v1")
public class Resource {

    public Resource() {}

    @Path("/get")
    @GET
    @Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    public ListOfPersons getListOfPersons() {
        ListOfPersons list = new ListOfPersons();
        System.out.print(list);
        return list;
    }

    @Path("/gets/{id}")
    @GET
    @Produces("text/xml")
    public Model showPerson(@PathParam("id") int id) {
        ListOfPersons list = new ListOfPersons();
        Model person = list.getList().get(id);

        System.out.println(list.getList().get(id));
        return person;
    }
}
