[06/27/11 14:41] <gbadner> sebersole, might be worthwhile to also have EntityBinding.getDeclaredEntityIdentifier()
[06/27/11 14:41] <sebersole> why?
[06/27/11 14:41] <sebersole> declared/not is more a function of the domain model
[06/27/11 14:42] <sebersole> well not even more... it IS a ...
[06/27/11 14:42] <sebersole> guess i am not seeing the benefit of getDeclaredEntityIdentifier here...
[06/27/11 14:42] <sebersole> i really want to stay away from adding things "just because"
[06/27/11 14:43] <sebersole> thats gets you in trouble
[06/27/11 14:43] <sebersole> later
[06/27/11 14:43] <sebersole> if there is a reason and a need, fine
[06/27/11 14:43] <sebersole> thats different

Why?
----
Historically, Hibernate relied on standard class-loading paradigms that targeted JSE and JEE deployment environments.  However, with the growth of OSGi and other modular systems those same approaches no longer always work.  So Hibernate needed a new approach that would allow it operate in all possible deployment environments.  

How?
----
In Hibernate 4 we leverage the ServiceRegsitry to define a pluggable service for providing interaction with the class-loading of the semantics of the environment in which Hibernate will be run. Specifically, the idea is to allow external entities (the user, the environment developers, etc) to define and "plug in" a custom scheme for class path interactions.  For example, an OSGi container could choose to provide Hibernate (either directly or as its JPA provider) and install a custom service for class loader interactions to override the default one.
