Question :2 Which two types of beans support Timer service?

a) Stateless session beans

b) Stateful session beans

c) Message Driven Beans

d) Entity Beans


I thought it was just (a) and (c). Why is (b) correct as well?

Hi,
Just in case you still not sure.
b) is not correct.
According to EJB core specification: - "Timers can be created for stateless session beans, message-driven beans, and 2.1 entity beans.
Timers cannot be created for stateful session beans[94] or EJB 3.0 entities"

Katrin
