## EJB Container

Enterprise beans (EJB components) are Java programming language server components that contain business logic. The EJB container provides local and remote access to enterprise beans.

There are three types of enterprise beans:

- Session beans represent transient objects and processes and typically are used by a single client.

- Entity beans represent persistent data, typically maintained in a database.

- Message-driven beans are used to pass messages asynchronously to application modules and services.

The EJB container is responsible for creating the enterprise bean, binding the enterprise bean to the naming service so other application components can access the enterprise bean, ensuring only authorized clients have access to the enterprise bean's methods, saving the bean's state to persistent storage, caching the state of the bean, and activating or passivating the bean when necessary.
