MOM provides guaranteed message delivery, and application developers do not need to know the details of remote procedure calls (PRC) and network/communication protocols to provide portability of the program.Maximize the degree of coupling between your application and your application system.because of the presence of MOM, individual applications only care about how messages are received and sent between mom, without having to focus on the other side of mom and how other

in two ways.0 synchronizationA subscriber or receiver calls the Receive method to receive a message, and the receive method blocks until it is able to receive the message (or before it times out)0 AsyncSubscribers or receivers can register as a message listener.

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 documents about activemq on the Internet, so I will n

The JMS (JAVA message Service,java messaging) API is a standard or specification of a messaging service that allows application components to create, send, receive, and read messages based on the Java EE platform. It makes distributed communication less coupled, and messaging services more reliable and asynchronous. This blog post we mainly introduce an important specification JMS in Java, because the appli

Receiver.java show how to use queue for point-to-point messaging in JMS, while Publisher.java and Subscriber.java show how to use topic for publish/subscribe messaging. The "Readme.txt" file (also on the Web) contains the commands to run various applications and the latest information about the code. Before attempting to run these applications, be sure to read the "install.txt" file and make the necessary
