A Java™ Message Service (JMS) activation specification is associated with a queue that uses message-driven beans (MDBs) to consume messages from the queue. The activation specification provides the information necessary for the queue to receive messages. For each continuous queue that you create, set up the activation specification at the cell scope.
To complete the configuration of JMS, in the External Systems application, you must update the configuration of the JMS queues to reflect the JNDI names created for the connection factory and queues.
