Hello,
I would like to implement the J2ee Application Service design pattern. I am relatively new to EJBs. It appears that the Application Service resides in the EJB tier and not in the client/web tier. However the Application Service implementation is not a EJB*. Can a class that is not an EJB reside in the EJB tier? If so how?
Thanks in advance,
Julien.

*The book I am refering to is the Core J2ee Design Patterns (Sun).
