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)

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

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!
 
It is sorta covered in the JavaRanch Style Guide.
