Hi everyone,
I'm trying to test a method that uses JDO and I can't figure out where
the problem is. I get this exception when I execute a test method.
org.datanucleus.exceptions.NucleusUserException: Object with id "" is
managed by a different ObjectManager
at
org.datanucleus.ObjectManagerImpl.findStateManager(ObjectManagerImpl.java:
756)
@Test
public void nuevaEntidadMismoNombreTest(){
Entidad entidad = new Entidad(nombre, cif, tipo, localizacion);
Entidad entidad2 = new Entidad(nombre, cif, tipo, localizacion);
Entidad nuevaEntidad = entidadDao.crearEntidad(entidad);
Entidad nuevaEntidad2 = entidadDao.crearEntidad(entidad2);
}
The method that I use to create the Entity is.
public Entidad crearEntidad(Entidad entidad) {
PersistenceManager pm = PMF.get().getPersistenceManager();
try{
Entidad nuevaEntidad = pm.makePersistent(entidad);
return pm.detachCopy(nuevaEntidad);
}finally{
pm.close();
}
}
For getting the PM I used the class recommended by Google
public final class PMF {
private static final PersistenceManagerFactory pmfInstance =
JDOHelper.getPersistenceManagerFactory("transactions-
optional");
private PMF() {}
public static PersistenceManagerFactory get() {
return pmfInstance;
}
}
I've also added the setting up of the datastore folowing the Google's
documentation instructions.
private final LocalServiceTestHelper dataHelper = new
LocalServiceTestHelper(new LocalDatastoreServiceTestConfig());
Can anyone tell my why I'm getting this exception?
Thanks in advance.
Regards.
