Yes, MDB is one type of EJB. (beside Session and Entity)

it is an asynchronous type of bean. which mean it has no client view.
after it receive a JMS from client it process the message with MDB and the client has already gone.

MDB is the bean to send messages via JMS. It is the bean that handle asynchronious messaging.

You can get more info by referring to chapters 22 and 23 of J2EE 1.4 tutorial.
