Hi, I am maintaining Transaction in one session and two CMP entity beans. And i have noticed that Container only manages transaction when there is a oracle error.. i.e. ORA.... So, if i simulate the rollback condition by passing a null vector, it doesn't manage transaction. The code is something like this. In a session bean method i am looking up two entity beans.. { // inserting record in one table TableA //for loop with a vector //insert record in anpther table TableB } Transaction Attribute is Required for stateless, Mandatory for both entity beans.

Hi,
I am maintaining Transaction in one session and two CMP entity beans.
And i have noticed that Container only manages transaction when there is a oracle error.. i.e. ORA.... So, if i simulate the rollback condition by passing a null vector, it doesn't manage transaction.
The code is something like this.
In a session bean method i am looking up two entity beans..
{
// inserting record in one table TableA
//for loop with a vector
//insert record in anpther table TableB
}
Transaction Attribute is Required for stateless, Mandatory for both entity beans.
Now if i make this vector null...it throws NullPointerException and doesn't maintain a transaction that means data gets inserted in TableA.
But if there is a oralce error it maintains transaction well.
What is the workaroud of this situation with Container Managed Transaction. otherwise i have an option to do it with Programmatic Transaction.
Thank you very much
