Hi,
As a newbie, I want to ask a yes/no question.
I use ThreadLocal to make the session thread safe, is that means all objects that query by session or find by session are all thread safe ?

Please, my lord.

Hibernate version:
hibernate 2.1.4

Mapping documents:
N/A

Code between sessionFactory.openSession() and session.close():
N/A

Full stack trace of any exception that occurs:
N/A

Name and version of the database you are using:
N/A

Debug level Hibernate log excerpt:
N/A

Hi,

As far as every thread obtain a dedicated session using that pattern, and you'll use the same thread for making calls on the session obtained, you have a isolated session from other threads.

Bye,

Roque

Hi rcnavarro,
Glad to get a reply, OK the session is isolated.
What I concern is the objects that query by this isolated session, are they thread safe too?

Let's assume I have a User object mapped with DB user table.
in the user object I make a hashMap as a member variable.

If this user object is thread safe, I don't need to worriy about the synchronized problem.

What say you ? Thank you very much.

If you have one session object per thread and you execute operations using this thread on the session, for example, you load and User object, modify the HashMap attribute and finally you update it, you don't be worry, with regards to object access synchronization, if another thread is updating the same object. It is due to every session has independent copies of the data.
Take a look at the points 10.2 and 10.3 of the Hibernate reference document.

Should I show my thanks indeed again?
Thank you very much.
I got the blue sky now.

Only, try to help to others

Good luck!!
