[hibernate-dev] how to get an EntityBinding by class name?

[Strong Liu]

okay, let me summary it here and see if i get it correct

1. entitybinding is keyed by (hibernate) entity name in metamodel
2. (hibernate) entity name should be FQN of the entity class (both hbm and annotation?)
3. it is correct assumption to throw exception when needs to look up an entitybinding but only entity class name provided by mapping and there is another entity name mapped to the same entity class

Before Hibernate APIs were just like the JPA APIs in that you could only reference entities by Class reference.  With the development of the entity-name feature, thats no longer always possible.

Otherwise, as already pointed out on this thread, you have a many-to-one correspondence (*a* single Class might reference multiple entity mappings).
