Dear All,
I am facing a strange issue using the KeyFactory.createKey() method : keys
generated by this method are stored as unowned relationships, but are
actually not recognized by the datastore viewer (the key-URL does not work).
Hopefully you could help me on this.
A few words about my source below.
Entity A is a root entity.
Entity B is a child of entity A.
Entity C is another root entity.
I use JDO for persistence.
All my entity primary keys are declared this way :
...
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
...
In my entity C, I need to store an unowned relationship to an entity B.
My parameters when creating C : the key IDs (type 'Long') of A and B.
My code to create entity C is quite simple, as follow :
...
Key aKey = KeyFactory.createKey(ClassA.class.getSimpleName(), akeyId);
Key bKey = aKey.getChild(ClassB.class.getSimpleName(), bKeyId);
entityC.setEntityBKey(bKey);
pm.makePersistent(entityC);
...
So far it's ok, but the bKey stored in entity C is not recognized by other
programs. Any clue ?
Thanks for your help.
Cyrille
