 Post subject: Using the same session for batch save

Hi All,
I am using Hibernate 2.1.6, In that to do batch insert, I retrive a new session each time for a TO and do the insert as below
for (Iterator iter = baseTos.iterator(); iter.hasNext();) {
to = (BaseTo) iter.next();
getSession().save(to);
}

Can I change this code to

Session ses = getSession();
for (Iterator iter = baseTos.iterator(); iter.hasNext();) {
to = (BaseTo) iter.next();
ses.save(to);
}

Basically Instead of getting new session for each save, I am using the existing session. What happens if one of the save fails??.

Thank you for your reply. I am using Hibernate 2.1.6. And the document is for Hibernate 3. But I think the concept applies to Hibernate 2.1.6.

One thing I did not understood from the document is that, why do we need to do beginTransaction() and commitTransaction(). I am using Stateless Session Ejbs. Do we have to do this???.

Thank You
D

If you are using Container Managed Transactions, you dont need to do it.
