Re: TransactionRolledbackLocalException caused stateful session gone?

Hi Karen,

The Runtime Exception if thrown in a bean is propogated in the transaction 
boundary of the container till it is handled.
Whenever the runtime exception is throw from a bean, the bean is destroyed.
So if the stateless session bean throws a runtime exception and the callee 
is a stateful session bean, it'll be destroyed.
You are almost right on why it happens.

Marking the execution on the stateless bean as requires new would help only 
to control the transaction boundaries.
If you do not want the stateful bean to be destroyed then catch the 
exception from the bean, wrap it with an application exception and return to 
the client.
This way the transaction is rolled back and the client is informed of the 
exception.

Lastly, for any bean the tx attribute can be specified in it's deployment 
descriptor on a per method basis.

Regards
Rajat

Music, states of happiness, mythology, faces belabored by time, certain 
twilights and certain places try to tell us something, or have said 
something we should not have missed, or are about to say something; this 
imminence of a revelation which does not occur is, perhaps, the aesthetic 
phenomenon.
