Hi!

I'm new to Hibernate and I have been playing around with it a bit, and notised when I was using HibernateTool to do som reverse-engieneering that it implemented Serializable in most of my persistent classes.

Can any one tell me the reason for this?
When I manually reverse-engineer my classes, should I implement it as well?
Is it some 'rules' for when I should/should not be using Serializable?

Thanks in advance

You will need to implement Serializable if you need to serialize your objects (usually to send them via a socket or to write them to a file). If you don't need that you don't have to implement Serializable.

If later you try to serialize an object that isn't Serializable, you'll ge an exception.

Anyway, there's no punishement for implementing it and not using serialization :)

ah -I see!
Thank you! I think I'll use Serializable then :)
