Hello everbody...

I download hibernate3.1 and replace with hibernate3.0 in my project.

It gives some error in save and update method.

in earliear version i used session.save(object, serializable id) but in new version this method is remove from org.hibernate.Session. and depricated in org.hibernate.classic.Session.

in new version there is only two method for save
1. save(object)
2. save(entityName, object)

if i used any of this method hibernate gives me "There is no Identifier found" this problem also appear in previous version but i can solved with save(object,serializable id).

please give me more information.. how to solve my problem.

regrards,
Nirav Pandya.

Hello,
I think in the release notes was mentioned that non existence of primary key is handled stricter.

You should carefully read
http://www.hibernate.org/250.html
+ the release nodes when you update.

May be post your mapping, so that everybody can see what kind of mappings does not work any more.

We are planning to remove support for domain objects which do not define primary key properties; hence the reason for moving those methods to the classic.Session.

You should consider that removing the support for save(object, identifier) removes the possibility to have a "generated by default" primary key that can have an assigned value.
I have upgraded to version 3.1.2 and noticed that I had to use the classic session.
In my case, I need an entity to have a few "standard" records (which I must assign a known id value) and other "custom" values, that the database (mysql) assigns.
If that is permanently removed, I won't be able to upgrate to newer versions...
