I have a Session Bean. It performs 3 actions inside one of its methods. 2
of the actions are updates to Entity Beans. The 3rd action is sending a
synchronous message to an external system. I want to have these 3 actions
performed in a transaction. I can see how the 2 entity bean updates will be
managed in the transaction; I don't know how to tell the container that the
transaction failed if the return value from sending a message to an external
system indicates failure.
So, if I have the following method on the Session Bean, MySessionBean:
MySessionBeanMethod()
{
myEntityBean1.updateNum1(num1);
myEntityBean2.updateNum2(num2);
int status = sendMessageToExternalSystem(msg);
if (status == 0)
// make sure that transaction is rolled back
}
I can specify the following transaction attributes in the deployment
descriptor:
MySessionBean's MySessionBeanMethod: Requires New
MyEntityBean1's updateNum1 method: Requires
MyEntityBean2's updateNum2 method: Requires
How do I ensure that if the MySessionBeanMethod(0 fails, that the whole
transaction is rolled back?
Thx,
Bill
