Hi Guys,
I jus did this small exercise in the Book "Head first EJB",i request you all to correct me if i'm gone wrong..

1)Booking a ticket for a rock concert ---Stateless Session Bean

2)A bank account --Entity Bean (obvious)

3)Searching a product database ---Stateless Session Bean

4)Dating service match-ups --Entity Bean (bcos it involves matching a person entity ( man &women))

5)Receiving submitted expense reports and sending
them out for approval --- Message DBeans (not sure)

6)Online expert diagnosis-you describe a symptom and the
system helps you determine the cause --MessageDBeans (not sure)

7)The books in a library --Entity Bean

By the way..my congrats to Bert Bates and Kathy Sierra for coming out with such a great book..its indispensible.

thanks for your time guys...

Regards
Sagar

There's a discussion on that exercise at Chapter 1 - HF Sark study group

We have a thread for each chapter, so as you have questions in the book you can find the corresponding chapter's thread. Please feel free to contribute to our discussions.

Thanks!
