What is the difference between session and entity beans? When should I use one or the other?
Created May 4, 2012
Alex Chaffee An entity bean represents persistent global data from the database; a session bean represents transient user-specific data that will die when the user disconnects (ends his session).
Generally, the session beans implement business methods (e.g. Bank.transferFunds
) that call entity beans (e.g. Account.deposit
, Account.withdraw
).
Please see What is an entity bean? and What is a session bean? for more information.
