what is the difference between stateless and stateful
sessions?
Answer Posted / buddheshwar ojha
BY rahul ojha
A stateful session bean maintains state between client and the statefulbean for a duration of time and once state is end it end session completely it also maintains data persistency(database).(Shoping card etc...)
A stateless session bean does not maintain conversation state for a longer time Instance variables used by a method of a stateless bean may have a state, but only for the duration of the method invocation. After a method has finished running either successfully or unsuccessfully, the states of all its instance variables are dropped.(HTTP , telephone line conversation etc...).
