Hi, I am using Hibernate 3.02 with entity-name feature. However, when I tried to delete an object: session.delete(target), where the target is the object to be deleted, it complaines unknown entity. I looked around and foudn a delete method in SessionImpl class: delete(String entityname, Object obj, boolean iscCascadeDeleteEnabled). I then used this delete. It seems working fine.

Is this a mismatch between Session interface and SessionImpl? How do a delete an object with an entity-name specified? Thanks.

I use session.delete(obj) quite frequently without any issues.

Is the Class of your target object above the same as the one your specifying for the entityname or is it a sub/super class ?

As with most of hibernate, it allows you to specify minimal information and determines the rest for you when possible. But if your class is a subclass that's not mapped, it'll work if you specify the superclass as the entity name, but not if you enter the subcass name.

session.save, session.update, session.get all have methods which support entity-name, only session.delete does not. It seems a bit odd. If I simply create a new Object and set the Identifer (a trnasitent object), the session.delete without an entity-name cannot help me locate the correct table to delete the object since I have several tables mapped to the same class. The only difference is the entity-name.


Also, in my application, session.save, session.update, session.get all work. Seems it should not be the xml mapping problem.
