Newbie : InterfaceObject/ Object / Dynamic Proxy

[Emmanuel Dupont]

All,

 

I use a Dynamic proxy for object A and B. I request A and B.

 

After the request, I have to manipulate the InterfaceA if not I have a
classCastException. 

But I can use the object B.

 

Where is my error ?

 

When you define an Dynamic proxy on A, you can still manipulate A, or only
InterfaceA ?

 

Here is my code :

 

            Query q = QueryFactory.newQuery(A.class, crit);

            broker.beginTransaction();

            Collection results = broker.getCollectionByQuery(q);

 

            Object[] tab = results.toArray();

 

            Object tabEdited = tab[0];         

 

            InterfaceA graEdited = (InterfaceA)tabEdited;

 

If I put A instead of InterfaceA I have a ClassCastException.

 

 

I have exactly the same code with B and I can manipulate B not InterfaceB.
That seems I have a mistake somewhere but I don't understand where...

 

Any idea what it could be ?

 

These is driving me nuts !!!!!!!

 

 

Thanks !
