Why is there a 2nd saveOrUpdate method that takes two arguments:

public void saveOrUpdate(Object object) throws HibernateException

public void saveOrUpdate(String entityName, Object object) throws HibernateException

Why would anyone want to specifically use the second one?

thanks,

I think that it's for use with the DOM model, rather than the POJO one. The object you pass in is always going to be the same class (Element, I think), so you use the entity name to discriminate.

There's no need to use any of the methods with entityName parameters if you're working with a pure POJO model.

Could you point to where that might be in the documentation? I saw some things about DOM4J, but it doesn't really discuss the saveOrUpdate methods.

I think the second one is used for getting specific EntityPersister {using entityName as key} from SessionFactory.

Chapter 18 is the one about XML data. That's the relevant part.
