Re: [hibernate-dev] Is there a way to have ServiceContributor per SessionFactory/EMF instead of per application classloader?

Honestly Scott, I am thoroughly confused now as to what you are wanting and what you are reporting. Your last code fragment[1] is close.  As I said earlier, building a SessionFactory typically involves individual service registries being used for each SF.  You have to go out of your way for that to not be the case.  I am pretty sure WF does not do this "going out of its way".  So not sure why the test does.  To me either: 1. write a unit test for StandardServiceRegistry(/Builder) 2. write a functional test for how building a SessionFactory handles StandardServiceRegistry. Instead you kind of do both and therefor do neither. I created a fork of your gist that shows a better test using (2), which I think is more what you are wondering about.  It is "better" imo because I *think* it better represents what you do in WF/Jipijapa - https://gist.github.com/sebersole/d93a28b1dcf16f6f7eb823b7341a9097
