Hi Santiago,
I think that the correct behavior is described in the EJB1.1
Specification
in the § 12.3.1 and more precisly in the Table 8 page 191.
ejbCreate is considered to be a business method.
The behaviour of the container depends on:
- the nature of the exception raised (Application Exception or
System exception and errors)
- the transactional attribute.
You can see for example that the container must mark the transaction
for rollback and throw TransactionRolledBack exception when it is a
SystemException
or Error raised during the ejbCreate and if ejbcreate is running in the
context
of the caller's transcation (Required, mandatory, Supports).
But with the same transactional attributes, if the exception raised
is an application exception, the container re-throw the exception
and it's up to the client to decide to commit/rollback the transaction.
I think that JOnAS 2.0 follow strictly the behavior described in this
table.
Note that in the previous versions of JOnAS the methods defined in the
home interface was not considered to be business methods, and the
behavior
was incorrect in such situations. It is now fixed.
Best regards,
