I have few conceptually qustions on Beans
How Entity beans survive a crash? Is it because of they hold only the data which is always there in DBMS or they do have another mechanism for preserving the data either in main memory or on the middle tier they use disk storage without DBMS.

Session Bean:
Stateless session bean is stateless for the same client or it does not remember the state in inter-client request?

Stateful session can be passivated then how it is different from entity bean? If it is not different in that respect then why do not we call an entity bean a stateful session bean?
