1. Container-Managed Persistence (CMP) - The container is responsible for providing the bean's state.

2. Bean-Managed Persistence (BMP) - The entity bean is responsible for giving its own state.

 

Message-driven Bean: is added with the Java Message Service (JMS) to give the ability to react as a message consumer and perform asynchronous processing between the message producer and the server.
