Subject: Exception Handling in EJB Transactions.
Hi,
The EJB 2.0 specification states that if an EJBException is thrown,
the container shall rollback the transaction while for Application level
Exceptions, the container does not. But since EJBException is a
RuntimeException(and thus is not checked), should the Application Exceptions
thrown in the Data/Business layer extend EJBException?? Or do we catch the
Application Exceptions and do a manual context.setRollbackOnly().
What would be the best way to handle rollback of Transactions when
Application Exceptions are thrown?
TIA,
Rajesh.
