Abstract
A major feature missing from EJB 1.1 was a bean that could receive messages via an intermediate queue; sessions and entity EJBs could only be called synchronously via their business logic and life cycle interfaces. EJB 2.0 introduced the message-driven EJB to rectify this problem, an EJB that is able to communicate with other EJBs and clients in an asynchronous manner.
