Answer 1

• Before deploying a stateful bean, it is in the Non-existent state . After a successful deployment, the EJB container performs any necessary dependency injection on the bean, and it enters the Finish state . At the moment, the bean is ready to have its methods called by the client application.
• When a session with a bean state is in a ready state, the EJB container can select passivate , that is, move it from the main memory for secondary storage. When this happens, the bean enters the Passive state .
• If the bean state instance was not available for a period of time, the EJB container will set the bean to Exist Not Working .
• A bean , beans .
• RequestScoped bean , HTTP--.
