Hi everyone:

I had seen this article:

http://www.hibernate.org/hib_docs/reference/en/html/transactions.html
The

Code:

session.disconnect()

and

Code:

session.reconnect()

method puzzled me all the time. I use

Code:

session.close()

when I complete a transaction.And I will use the

Code:

session=sf.openSession()

when I need a new session. But when should I use the session.disconnect() and session.reconnect() method?
Please give me some example .Thks![/code]

Hi, I am a newbie in Hibernate and I am thinking about applying Hibernate to
a project I will work on in the next few month. And for the project,
concurrency may not be high but data stale can be a disaster. Thus, I am
wondering if it is better to always use session.disconnect() in the business
layer. In fact, if anybody can better explain the difference between these
two methods, i will so much appreciate. Is it true that to use
session.disconnect() may not be necessarily better, but no doubt more
secure?

It is exactly what my problem is. What different between session.close() and session.disconnect() ? [/url]

by calling session.disconnect(), you can reuse the session later (you may also call session.reconnect()).
When you close a session, then you have to discard it... it is _dead_.

reconnect is usefull when having long transaction, for example that spans many user requests, but be very carefull when doing such things, be sure you know exactly what you are doing.
