transaction exceptions

[Lucas Smith]

Howdy!


I have two SLSB (A and B) with methods:

A:
TransactionAttribute.REQUIRED
public void a() {
    b.b();
}

B:
TransactionAttribute.REQUIRES_NEW
public void b() {
    throw new RuntimeException();
}

I suppose that bean A will receive EJBException and can continue with the transaction if the excepion is caught? If the exception is not caught then bean A is discarded?
The transaction of B is rolledback and bean B is discarded?

Am I right?

In EJBs, we have 2 type of exceptions are there
1) System Exception
2) EJB Exception

Transaction {
BusinessMethod1();
BusinessMethod2();
BusinessMethod3();
}

While performing above transaction, if any exception has happend

1) If Exception is System Exception:
Then Container will come into picture, rollback the data.

2) If Exception is EJB Exception:
Then developer will handle that the exception.


In your case.

Inside Session Bean A Business Method, user calling the Session Bean B Business Method.

Session Bean B business Method throws Exception, so that Session Bean A business method not handle the exception, it is ejb exception. User should take care while handling these excepions.
