Name and version of the database you are using: Db2 7.2.5

I was consistently getting the above exception. Then, I after going through a few posts I changed the version property field of my class from

protected Integer version = null;
to
protected Integer version = new Integer(1);

and I stopped getting the TransientObjectException and Instead got another exception: NonUniqueObjectExection.

Are these related in any way?

In this context I want to know,



1. Is this change correct? Should we continue using it?
2. Is the second error a consequence of this change?
3. Is there any other major implication of using this? How will other parts of the application get affected due to this change?


Please advise

Thanks,
Hitesh

Hai

I am trying to guess where your problem occured.

1) The First Exception says that you are trying to save an object into the database without calling session.save(Object), also you are some where trying to flush the Hibernate session after closing it or before .Try to not to flush and check it.

2) The second Exception was reveled after u have done something.The meaning of the secon exception is the object you are trying to save has an Identity value(in java jargon it is object memory value and in database jargon it is the PK value in the table) is already in the table with a different record.You are trying to insert with the same PK value.Please check the table in yuor data base .


Please reply me how much this has helped you

Hi shantha,

I am sure your two answers are not to the point.
