three questions here:

1st,
is that possible to have isOpen() true but isConnected() false?

2nd
is that possible to have isOpen() false but isConnected() true?

3rd
when the both return true and when they both return false?

Hello,

you can disconnect a session from the underlying jdbc connection, which is useful for long session handling. Read about this in the Hibernate reference. In my book is not yet a complete example project for this kind of usage.

I suppose that the session is still open in this moment but I did not use this approach, so you may verify it.

A closed session is no longer of use and the jdbc connection is released.

Best Regards

Sebastian
