Hello all,

For a simple test with Hibernate's XML mapping capabilities, I tried to save a mapped element to the database. The error message says entity-mode is pojo, while i specified 'dom4j'.

Am I making a mistake somewhere in the code or the mapping file? Both are a rather faithful reproduction of the docu examples.

Best regards, Jos

Hibernate version:

The last bit should be:

Thanks, Steve!
you're right, I was using the wrong Session object.
In fact,

works fine too.

Is there a special reason, that one needs two Session objects? It's rather confusing. I'd prefer code like:

LOL. We just had this discussion a few days ago.

The reason for not having the ability to specify in which entity mode to open the session from the factory is that SessionFactory.openSession() is overloaded to allow a number of various parameters. Adding the ability to specify an entity mode on top of all that would mean an explosion of those openSession() methods.

If you are only working with dom4j data, you can use the hibernate.default_entity_mode setting which determines the entity mode for the initial session obtained from the factory.

I'm planning to mix use of the different types of sessions, so the hibernate.default_entity_mode is not an option. I see that the allowed openSession parameters cannot be used after instantiation, so it's not possible to remove any functions with parameters that could be added later. What you could do however, is to allow for null values. E.g.

and use the default value for every parameter that has value null. I guess some people would find this an ugly solution, however.
The confusion of having nested session is, in my opinion, considerable and it would be nice if it could be avoided.

I hear you.

We definitely want something different here; but the best how to acheive that is still being determined. If you have any suggestions after using this for a bit please let us know (though it will not include nullable parameters ;)
