Hello, all,
I am using CMP for session facades and local entity beans. Both entity beans and the
session facade are put into CMP with transaction option of 'required' in ejb-jar.xml
In my SessionFacade.facade() method, I call EntityBean1.bean1() and then
EntityBean2.bean2(). My intention is to roll back the facade() transaction if either
bean method is failed. However, I observe that, once bean1() is returned the database
will be updated. If there is an exception thrown from bean2(), no roll back happens.
This is totally against my assumption. I am not sure whether it is caused by nested
transaction not supported by EJB2.0 and weblogic currently.
I will appreciate it if any one can provide a definite answer.
Another related question is, which one of the followings is qualified as a 'nested
transaction'? My intention is to have a coarse update for my entity bean.
A) SessionFacade.facade(){ bean.setA(); bean.setB();}
B) EntityBean.updateBean(){ setA(); setB(); }
Answer 1: A) but not B)
Answer 2: both A) and B).
Thanks,
Denis
