Big Hi to everyone! This is my first post here. I have been a silent observer of this forum for the last three months and I find it great.
I have cleared SCEA part 1 with 79% five days ago. And now well � I am starting to prepare the part 2. I am quite confused about the discussions on shopping cart (or booking) cart. I have discovered that the issue of the shopping cart is one of the most vividly discussed in this forum and really mystified because I cannot find any connection to the requirements.
According to the requirements the booking and payment can be separated in time. A customer can have many unpayed bookings and can pay for these bookings in a separate session. How can a storing of the state (Itinerary/Flights/Seats) in a SFSB without storing it in a database be helpful in this situation?
I would like to emphasize that I am not speaking of Transfer Object (TO/DTO/VO) or Stateful Session Beans for storing user / customer /login data. These are separate problems and it wouldn�t help if you call a DTO or a Business Service �Shopping Cart�. I think �Shopping cart� is a well-established term and it is misleading to use the term for something else.
Can somebody explain how can a Stateful Session Bean (like in PetStore) for the Shopping/Booking cart help in the booking process?
I just hope that my question is not especially stupid.
Anyway, many thanks in advance.
