If you call a method on an entity bean after having called remove() do you get a NoSuchObjectException or EntityNotFoundException ie is the bean in the "does not exist " state?

You get a NoSuchObjectException or NoSuchObjectLocalException are thrown if the object is removed( which could mean the entity bean object he has a reference to/or the entity the object is refereing to which means the clients reference is void now) and client is calling a method on it, where as the NoSuchEntityException is thrown by the bean to the container during one of the callbacks/methods where it could not complete the operation because the entity is removed from the database(underlying persistent store). Hope this helps.

Story like this gets better after being told a few times. Or maybe it's just a tiny ad:
