I have a design issue i am not sure about. i have a hibernate object i use in various threads. i am fetching the same object from the database and since it is done in different sessions they are allocated with different JVM ids.

I put both objects (which should reflect the same object in the database) in different sets.

My question is: how do i make sure their data is synchronized?
My application is not very intense so for now i don't care too much about locking but more about data consistency. if i would have worked in the context of the same session the answer would have been very simple. but i am working in a multi threaded environment and the life time of the objects is rather long (up to an hour and maybe more).

Which hibernates' strategy is the best for me?. please advise.
