Message Driven Bean

A message driven bean (MDB) is a bean that contains business logic. But, it is invoked by passing the message. So, it is like JMS Receiver.

MDB asynchronously receives the message and processes it.

A message driven bean receives message from queue or topic, so you must have the knowledge of JMS API.

A message driven bean is like stateless session bean that encapsulates the business logic and doesn't maintain state.
