it simply says that your test method is not transactional which is true.
here a code which works:
@Stateless
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public class Movies {
@PersistenceContext(unitName = "movie-unit", type =
PersistenceContextType.TRANSACTION)
private EntityManager entityManager;
public void addMovie(Movie movie) throws Exception {
entityManager.persist(movie);
}
public void deleteMovie(Movie movie) throws Exception {
entityManager.remove(entityManager.find(Movie.class,
movie.getId()));
}
public List<Movie> getMovies() throws Exception {
Query query = entityManager.createQuery("SELECT m from Movie as m");
return query.getResultList();
}
}
public class MoviesTest extends TestCase {
@EJB
private Movies movies;
@PersistenceContext
private EntityManager entityManager;
public void setUp() throws Exception {
Properties p = new Properties();
p.put("movieDatabase", "new://Resource?type=DataSource");
p.put("movieDatabase.JdbcDriver", "org.hsqldb.jdbcDriver");
p.put("movieDatabase.JdbcUrl", "jdbc:hsqldb:mem:moviedb");
EJBContainer.createEJBContainer(p).getContext().bind("inject",
this);
}
public void test() throws Exception {
movies.addMovie(new Movie("Quentin Tarantino", "Reservoir Dogs",
1992));
movies.addMovie(new Movie("Joel Coen", "Fargo", 1996));
movies.addMovie(new Movie("Joel Coen", "The Big Lebowski", 1998));
List<Movie> list = movies.getMovies();
assertEquals("List.size()", 3, list.size());
for (Movie movie : list) {
movies.deleteMovie(movie);
}
assertEquals("Movies.getMovies()", 0, movies.getMovies().size());
}
}
Note: i added to movie entity:
@Id
@GeneratedValue
private long id;
+ the getId method.
