How many classes (interfaces count as classes for this question) are the minimum necessary to define an EJB for deployment?
Name them assuming that the EJB is called MyEJB.

EJB being a vast topic can have many questions.Some of the common questions are:
a) What makes a java class an EJB.
b) What are the various transaction attributes and isolation levels.
c) Life cycle of Entity and Session Beans.
d) How does the container manage the resources.
e) Can we use user defined threads in EJB. If not then why?

Simple but asked.
What are the call back methods of an EJB?
What does the isolation level serializable do to the transaction?
