Re: Issues in calling DAO from Sateless session bean

The exception thrown is runtime or application (user defined exception
or any sub class of exception class)?

EJB container rollbacks transaction only if its system exception. Check
what kind of exception you are throwing.

Hope this helps

Subject: Issues in calling DAO from Sateless session bean

I have a stateless session bean which uses container managed
transactions. I
had to call
a DAO in which I insert two records, from the session bean. If there is
an
exception while inserting
second record in the DAO, I am facing the problem that the first record
is
already commited
inspite of throwing the Exception.

I was able to have a workaround by calling setRollbackonly on the
transaction context. I am not sure
why this should be done. If the transactions are managed by container
and I
am not calling commit
explicitly why should I call setRollbackonly.

Does anyone have any idea why this works this way?

Regards,
Koya Suresh
