Hi All,
I am Nutan developing an application using Google App Engine and Java.
<code>
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Movie {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key movieId;
@Persistent
private String movieName;
@Persistent
private Language language;
@Persistent(mappedBy="movie")
private List<Person> actor;
@Persistent(mappedBy="movie")
private List<Person> actresses;
}
</code>
This is Movie data class where actor is a list.
Where person class is below
<code>
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Person {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key personId;
@Persistent
private String personName;
@Persistent
private String gender;
@Persistent
private int categoryId;
@Persistent
private Movie movie;
}
</code>
But when I'm trying to save movie using the following code
<code>
Country c = new Country();
c.setCountryName("India");
Movie m = new Movie();
m.setMovieName("Athadu");
m.setCountry(c);
m.setRating("5");
Person p = new Person();
p.setPersonName("Mahesh Babu");
p.setGender("Male");
ArrayList actors = new ArrayList();
actors.add(p);
m.setActor(actors);
PersistenceManager pm = PMF.get().getPersistenceManager();
try {
pm.makePersistent(m);
} finally {
pm.close();
}
</code>
The following error is coming.
javax.jdo.JDOFatalUserException: Error in meta-data for
com.moviediary.datastore.Movie.actresses: Class
com.moviediary.datastore.Movie has multiple relationship fields of
type com.moviediary.datastore.Person: actresses and actor. This is
