In this tutorial we will cover Java EE Stateful Session Bean passivation and activation mechanism.
1. Introduction
Stateful Session Beans are usually coupled with some given client and – as the name states – they keep state across client invocations.
Since a conversation with a client may be long-lived, and many simultaneous clients may exist at the same time, the EJB container must have a mechanism of releasing resources that may not be needed at some precise moment.
