Session Beans have a lifecycle callback function @PostConstruct, it's different than the class constructor, because it will be called later after dependence injection.
So my question is, can man call another EJB which is injected with @EJB in this lifecycle function and if yes, how about the transaction propagation? (JTA, CMT, transactional persistence context)
EJB 3.1 specification, p. 374, 13.6.5 wrote:The term "an unspecified transaction context" is used in the EJB specification to refer to the cases in which the EJB architecture does not fully define the transaction semantics of an enterprise bean method execution.
This includes the following cases:
- The execution of a PostConstruct, PreDestroy, PostActivate, or PrePassivate callback method of a session bean with container-managed transaction demarcation (Except Singleton PostConstruct/PreDestroy methods)"
