Немаршаллинг нулевой ошибки в JAX-WS WebMethod

/ 13 июля 2020

Я новичок в Java EE и WebServices, реализую базовый c one с помощью некоторого учебника. Все работало нормально, когда присутствовали только функции getMov ie, getMovieList, но затем я попытался добавить функцию addMov ie, и внезапно она начала выдавать ошибку, не могли бы вы помочь в решении этой проблемы. Заранее спасибо.

Mov ie. java

public class Movie implements Serializable {

        private long movieId;
        private String movieName;
        private int yearMovieRelease;
...
...Getters and Setters...
}

MovieData. java

@Singleton 
@LocalBean
@Startup 
public class MovieData {
        
        private List<Movie> movies;
        
        @PostConstruct
        public void initial(){
                movies = new ArrayList<Movie>();
                
                movies.add(new Movie(1,"Movie1",2015));
                movies.add(new Movie(2,"Movie2",2016));
                movies.add(new Movie(3,"Movie3",2017));
                movies.add(new Movie(4,"Movie4",2018));
                movies.add(new Movie(5,"Movie5",2019));
                
        }
        
        public Movie getMovie(int movieId){
                Movie findMovie=null;
                
                for(Movie movie : movies){
                        if(movie.getMovieId()==movieId){
                                findMovie=movie;
                                break;
                        }
                }
                
                return findMovie;
        }
        
        public String addMovie(Movie movie){
                movies.add(movie);
                return "Movie added Successfully";
        }
        
        public List<Movie> getMovieList(){
                return movies;
        }
}

MovieServiceJAXWS. java

@Stateless
@LocalBean 
@WebService(serviceName = "MovieServiceJAXWS")
public class MovieServiceJAXWS { 
        
        @EJB MovieData movieData;
        
        @WebMethod
        public Movie getMovie(@WebParam(name="movieId") int movieId){
                return movieData.getMovie(movieId);
        }
        
        @WebMethod
        public List<Movie> getMovieList(){
                return movieData.getMovieList();
        }
        
        @WebMethod
        public String addMovie(Movie movie){                
                return movieData.addMovie(movie);
        }
}

Я внес следующие изменения в Mov ie. java

# 1 

@XmlRootElement(name = "movie")

# 2

конструктор по умолчанию без аргументов 

        public Movie(){
        }

а потом заработало ...

Soap вывод 

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <ns2:addMovieResponse xmlns:ns2="http://soapj8test.tanmshar.com/">
         <return>Movie added Successfully</return>
      </ns2:addMovieResponse>
   </soap:Body>
</soap:Envelope>
