Issue #633: Issues with JDO Casting & Full Qualified Names

Hi,

As I've feared.. Fully Qualified Names in casting not working, throws an identifier expected exception:

package com.test;

import java.util.HashMap;
import java.util.Map;

import javax.persistence.Embeddable;
import javax.persistence.Entity;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

public final class F328
{

public static void main(String[] args)
{
  EntityManagerFactory emf = Persistence.createEntityManagerFactory("objectdb:$objectdb/db/test4.tmp;drop");
  EntityManager em = emf.createEntityManager();

  em.getTransaction().begin();
  MyEntity entity = new MyEntity();
  entity.embeddeds.put("test", new EmbeddedA());
  entity.embeddeds.put("test2", new EmbeddedB());
  em.persist(entity);
  em.getTransaction().commit();

  // FAIL WITH EXCEPTION HERE
  query = "SELECT COUNT(e) FROM MyEntity e WHERE ((com.test.F328.EmbeddedB)e.embeddeds.get('test2')).superB = '123'";
  System.out.println("4: " + em.createQuery(query).getSingleResult());

  em.close();
  emf.close();
}

@Entity
public static final class MyEntity
{
  Map<String, EmbeddedBase> embeddeds = new HashMap<String, EmbeddedBase>();
}

@Embeddable
public static class EmbeddedBase
{
  String base = "TEST";
}

@Embeddable
public static class EmbeddedA extends EmbeddedBase
{
  String name = "Alex";
}

@Embeddable
public static class EmbeddedB extends EmbeddedA
{
  String superB = "123";
}
}

Please any help.. I am starting to get really annoyed with all that map related workaround and stuff...

thanks very much!!!

The problem is only with inner classes, which are not expected to be supported by JDO.

Try:

package com.test;

import java.util.HashMap;
import java.util.Map;

import javax.persistence.Embeddable;
import javax.persistence.Entity;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

public final class F332
{

    public static void main(String[] args)
    {
        EntityManagerFactory emf =
            Persistence.createEntityManagerFactory(
                "objectdb:$objectdb/db/test4.tmp;drop");
        EntityManager em = emf.createEntityManager();

        em.getTransaction().begin();
        MyEntity entity = new MyEntity();
        entity.embeddeds.put("test", new EmbeddedA());
        entity.embeddeds.put("test2", new EmbeddedB());
        em.persist(entity);
        em.getTransaction().commit();

        // FAIL WITH EXCEPTION HERE
        String query = "SELECT COUNT(e) FROM MyEntity e " +
            "WHERE ((com.test.EmbeddedB)e.embeddeds.get('test2')).superB = '123' ";
        System.out.println("4: " + em.createQuery(query).getSingleResult());

        em.close();
        emf.close();
    }
}

@Entity
final class MyEntity
{
    Map<String, EmbeddedBase> embeddeds = new HashMap<String, EmbeddedBase>();
}

@Embeddable
class EmbeddedBase
{
    String base = "TEST";
}

@Embeddable
class EmbeddedA extends EmbeddedBase
{
    String name = "Alex";
}

@Embeddable
class EmbeddedB extends EmbeddedA
{
    String superB = "123";
}
