Stateful vs. Stateless Session Beans
A stateful session bean will maintain a conversational state
with a client. The state of the session is maintained for
the duration of the conversation between the client and the
stateful session bean. When the client removes the stateful
session bean, its session ends and the state is destroyed.
The transient nature of the state of the stateful session
bean should not be problematic for either the client or the
bean, because once the conversation between the client and
the stateful session bean ends, neither the client nor the
stateful session bean should have any use for the state.
A stateless session bean will not maintain conversational
states for specific clients longer than the period of an
individual method invocation. 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. The
transient nature of this state gives the stateless session
bean beneficial attributes, such as the following:
