Before you can use the message service to send and receive messages, you must add and configure the message service parts. Once you configure the message service, it is available to every server that you create.
You can use the Management Console to add and configure message service parts:
Permanent destinations – message queues and topics. Add one message queue for each message recipient. To identify the subject of messages to which you want to subscribe, add message topics. You can also create message queues and topics using the CORBA API or the JMS createQueue and createTopic methods. Although these JMS methods are not portable, creating message queues and topics programmatically can significantly reduce the system administrator’s work.
To restrict access to a message queue, define security roles for message queue producers and consumers. You can also add security roles to a topic.
Connection factories – connection factories enable JMS client applications to establish connections with the message service.
Message listeners – to provide asynchronous message notification for clients and components, implement a message listener, and install it on a message queue or topic.
