1.The previous section briefly introduced the basic concepts of JMS. This section uses an example to help you understand the basic concepts of the previous section. the first thing to do is to select a JMS provider. You do not need to consider this in the javaee environment. we chooseActivemq, Official address: http://activemq.apache.org /.There are many document
destinations. At this point, you (or your development team) will question whether a simple JMS client solution is really simple.
Session Bean and JMS
Combining session Beans with JMS is a viable enterprise-oriented solution. The session Bean is designed to fulfill requests for business services. An enterprise messaging system must be queried to fulfill such a r

(3) Use connection to establish a session
(4) use the session and management object destination to create the messagesender for the message producer.
(5) Use messagesender to send messages
Example of a message sender:
