The message-driven bean (MDB) is a stateless component that is invoked by the EJB container when a JMS message arrives for the destination (topic or queue) for which the bean has registered. An MDB is a message consumer, and like other JMS message consumers, it receives messages from a destination because it implements the javax.jms.MessageListener interface. It is then able to perform business logic based on the message contents. MDBs receive JMS messages from clients in the same manner as any other JMS servicing object. A client that writes to a destination has no knowledge of the fact that an MDB is acting as the message consumer. MDBs were created to have an EJB that can be asynchronously invoked to process messages, while receiving all of the same EJB container services that are provided to session and entity beans. When a message is sent to a destination, the EJB container ensures that the MDB registered to process the destination exists. If the MDB needs to be instantiated, the container will do this. The onMessage() method of the bean is called, and the message is passed in as an argument. MDBs and stateless session EJBs are similar in the sense that they do not maintain state across invocations. MDBs differ from stateless session beans and entity beans in that they have no home or remote interface. Internal or external clients cannot directly access the MDBs methods. Clients can only indirectly interact with MDBs by sending a message to the destination. The EJB deployer is the person responsible for assigning MDBs to a destination at deployment time. The EJB container provides the service of creating and removing MDB instances as necessary or as specified at deployment time.

The EJB container allows for the concurrent consumption of messages and provides support for distributed transactions. This means that database updates, message processing, and connections to Enterprise Information Systems using the Java EE Connector Architecture (JCA) can all participate in the same transaction context. The EJB container or application server provides many services for MDBs, so the bean developer can concentrate on implementing business logic. Here are some of the services provided by the EJB container:

The EJB container also provides the following services based on the entries in the deployment descriptor file.
MDB Life cycle Management The life cycle of an MDB corresponds to the life span of the EJB container in which it is deployed. Since MDBs are stateless, bean instances are usually pooled by the EJB container and retrieved by the container when a message is written to the destination for which it is a message consumer. The container creates a bean instance by invoking the newInstance() method of the bean instance class object. After the instance is created, the container creates an instance of javax.ejb.MessageDrivenContext and passes it to the bean instance via the setMessageDrivenContext() method. The ejbCreate() method is also called on the bean instance before it is placed in the pool and is then made available to process messages. Exception Handling MDBs may not throw application exceptions while processing messages. This means that the only exceptions that may be thrown by a MDB are runtime exceptions indicating a system-level error. The container will
