What is Message Driven Bean

Answered by Jey on 2005-05-08 12:30:37:

Message Driven Bean (MDB) is an enterprise bean which runs inside the EJB container and it acts as Listener for the JMS asynchronous message . It does not have Home and Remote interface as Session or Entity bean. It is called by container when container receives JMS asynchronous message. MDB has to implement MessageListener which has a method onMessage(Message msg). When the container calls the MDB it passes the message to onMesage() method and then MDB process that message.
