Как соединить два дочерних узла xamDiagram - инфрагистика

Я также столкнулся с этой проблемой. Возможно, это поможет.

@POST
@Path("/{par}")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Object centralService(@PathParam("par") String operation, Object requestEntity) throws JSONException {

    ObjectMapper objectMapper=new ObjectMapper();

    Cars cars = new Cars();  
    Seller seller = new Seller();
    String someThingElse;

    HashMap<String, Object> mapper = new HashMap<>(); //Diamond )))

    mapper = (HashMap<String, Object>) requestEntity;

    cars=objectMapper.convertValue(mapper.get("cars"), Cars.class);
    seller=objectMapper.convertValue(mapper.get("seller"), Seller.class);
    someThingElse=objectMapper.convertValue(mapper.get("someThingElse"), String.class);

    System.out.println("Cars Data "+cars.toString());

    System.out.println("Sellers Data "+seller.toString());

    System.out.println("SomeThingElse "+someThingElse);

    if (operation.equals("search")) {
        System.out.println("Searching");
    } else if (operation.equals("insertNewData")) {
        System.out.println("Inserting New Data");
    } else if (operation.equals("buyCar")) {
        System.out.println("Buying new Car");
    }

    JSONObject json=new JSONObject();
    json.put("result","Works Fine!!!");


    return json.toString();

}
