Hi all
I am experiencing a problem with handling transactions in EJB
My application has the following
1. A servlet invokes a business method in stateful session bean "SFBean"
2. "SFBean" uses a helper class "Helper" to process some business logic.
3. In "Helper" I make use of two entity beans (BMP)
Here my problem is that I want the use of two entity beans as a single transaction.
If I start a UserTransaction in "Helper" I am getting not supported Exception as nested transactions are not allowed
Can any body suggest me How Do I go abt solving this
Thanks in anticipation

Build a stateless session bean and call your BMP's from within that.
