Entity Bean: is a persistent object that presents object views of the data, generally a row in a database. They have the primary key as a unique key identifier. Multiple EJB clients can give each entity bean. Entity beans may provide system shutdowns. Entity beans can have two kinds of persistence

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.
