A message-driven bean is an enterprise bean that allows J2EE/Java EE applications to process messages asynchronously.

A message-driven bean is an enterprise bean that allows J2EE/Java EE applications to process messages asynchronously. It acts as a JMS message listener, which is similar to an event listener except that it receives messages instead of events. The messages may be sent by any J2EE/Java EE component, or by a JMS application, or a system that does not use Java technology at all.
