EJB 2.0 integrates the EJB component architecture with the Java Message Service (JMS) asynchronous messaging API. EJB 2.0 allows you to define message-driven bean components to respond to JMS messages. An MDB component is similar to an EJB stateless session bean, but the MDB component responds only to JMS messages and has no direct client interface.
For information on JMS and MDB components, see Chapter 31, “Using the Message Service,” in the EAServer Programmer’s Guide.
