The message system that implements the JMS specification also provides all-round functions required for management and control, as shown in ActiveMQ.Administered Objects

look at this, application a sends a message to the server, and then application B receives a send from the server, and through this diagram we analyze the benefits of JMSFigure 1 JMS CommunicationProvides message flexibilityApplication A communicates with application B by using the Application Programming Interface (API) of MOM to send messages. MOM routes the message to Application B, so that the message can exist in MOM, and mom is responsible for

After receiving the message, the receiver must respond to the Message Queue successfully.

B. Concepts involved:
In the publish/subscribe message model, the publisher publishes a message that is delivered to all clients through topics. In this mode, both the publisher and the subscriber are anonymous, that is, both the publisher and the subscriber do not kn
What if the phone can only make real-time calls, without messages and text messages? A phone call came, just didn't have time to pick up, then the phone to send the message must not be received. Why not save the information first and then get the information when the user needs to see it? Along with this doubts, short-term interest and message came into being, whether the phone is turned on or not, we can get the information in the time. JMS provides
customer is sent only to a single target object.Message-oriented middleware (oriented Middleware,mom) solves the above problems better. The sender sends the message to the message server, which stores the message in several queues and forwards the message to the recipient at the appropriate time. In this mode, sending and receiving are asynchronous, the sender does not have to wait; the life cycle of the two is not necessarily the same: the receiver
emergence of the jms api, most products use either of the "point-to-point" or "Publish/subscribe" methods for message communication. JMS defines the specifications of the two message sending models, which are independent of each other. Any JMS provider can implement one or two models, which are their own choices. The JMS

What if the phone can only perform real-time calls without messages or text messages? When a phone call arrives, the phone call cannot receive any information. Why can't I save the information first? When the user needs to view the information, I can get the information again? Along with this doubt, short messages and messages came into being. no matter whether the phone is turned on or not received in time, we can get the information in it.
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.

1. Background
At present, CORBA, DCOM, RMI and other RPC middleware technologies have been widely used in various fields. But in the face of a distributed system that is growing in size and complexity, these technologies also show their limitations: (1) synchronous communication: After a client makes a call, it must wait for the service object to finish processing and return the result before it can continue; (2) tight coupling of customer and service object lifecycle: Client process and servic

Java Message Service (JMS) is a Java Message Service. It provides standard interfaces for generating, sending, and receiving messages, simplifying the development of enterprise applications. It supports two message communication models: point-to-point (P2P) model and pub/Sub Model. The P2P model specifies that a message can only have one receiver; pub/subThe model allows a message t
