Hi,

I’m wondering if it's possible to configure subclasses without any discriminator? When you use SINGLE_CLASS inheritance strategy you must specify a discriminator column/value. By default is will populate the column as DTYPE which results in the following error:
ORA-00904: "DTYPE": invalid identifier

I have an entity which extends from another base entity. The parent entity has all the persistence annotations. The child class is used only for creating new records since I have some additional business logic around how the object can be created. I know I can modify this to have my child simply wrap the parent instead, decorator pattern, but I was wondering if it was possible through inheritance?

So for instance, I want to be able to do the following:

@Entity
@Table(name="MY_BASE_OBJECTS")
public class BaseObject
{
@Column(...)
...
}

@Entity
public class CreatableObject
extends BaseObject
{
...
}

Any help would be greatly appreciated!
Thanks.
