ejbActivate and ejbPassivate methods are not significant in Stateless session bean.

As the name implies, a Stateless session bean does not maintain any state (instance variables values) across methods for a particular client, ejbActivate () and ejbPassivate () methods do not have significance in Stateless session bean. So the Container can assign different beans from the pool to the client for successive methods so developer needs not to write code in these methods for stateless session bean.
