Make sure you put the interfaces on a shared classloader. The warning is just that - no need to worry
These are Entities and I didn't create an interface for any of them. I haven't seen this used a lot in the examples, so I just went the way of just having the Entity class itself.
How do you go about putting setting classes in certain classloaders. And specificying which classloaders to use and if the are shared or not? I have never had to dig deep into classloaders before, so I'm kind of a rookie there. Any documentation to point me to would be awesome.
You are trying to access the same instance of an entity from two applications at once? I don't think you (or hibernate) can do that. I was assuming you were wanting to communicate using remote interfaces on session beans. EJB3 forum might also be able to help.
