Hi,

I'm trying to understand if it's possible to get an ObjectNotFoundException when trying to use the load() method on a non existing entity.

According to the doc, it seems it should be the expected behavior, but I never get it, only an empty Proxy on the entity, as I'm using the default LazyLoading behavior.

thanks for confirming if it's possible

Well, it is the expected behavior that you get a proxy from the load method. The behavior is the load method doesn't hit the database until a property of the bean is requested. So at first it returns a Proxy and then when you access the property of the bean then it will throw an ObjectNotFoundException if the id is non-existent or LazyInitializationException if the access is out of session's scope. So always use session.get() if you are not sure of the existence.

thanks for the confirmation littypreethkr, that's helpful.

I still find it kind of weird not to get the ObjectNotFoundException straight after the load() call on a non-existant entity.
I suppose it's probably hard to implement it this way, but fair enough, at least now I know exactly what to expect!

cheers
