So are you saying it's better not to use them in EJBs ? Or mixing both
(EJBs and Managed Bean transactions) is not appropriate ? What happens if
we have this ? Is the method propagated as expected ?
@Stateless
public class MyEJB {
@Inject
private MyBean myBean;
public void defaultRequiredMethod() {
myBean.defaultTxMethod();
}
}
@Transactional
public class MyBean {
public void defaultRequiredMethod() {
myBean.defaultTxMethod();
}
}
