The Java Message Service (jms) application interface is an API for Message-oriented middleware (MOM) on the Java platform. It is used between two applications, or send messages in a distributed system for asynchronous communication. Java Message Service is an API unrelated to a specific platform. Most MOM providers provide support for JMS. Jms can also be referre
RMI uses synchronous communication, and JMS uses asynchronous communication.There are two main concepts in JMS: The message broker and the destination (destination). The disadvantage of synchronous communication, which can be solved by using JMS: Run Apache-activemq-5.10.0-bin[1]\apache-activemq-5.10.0\bin\win32 under Activemq.bat to start the

The Topic mechanism of message middleware does not normally save messages. Without a connection, you will not receive a message when you connect again without losing your connection. This mechanism is well applied to scenarios where messages can be lost. Of course, message middleware has the ability to save messages. Durablesubscriber is defined in the
The meaning of the JMS cluster is to enhance the concurrency capability of the system in processing messages, and to build such a cluster, there are three steps:
1. Configure the database used for JMS message persistence
2. Configuring a distributed JNDI environment
3. Configuring Distributed JMS Clusters
In the JBoss cluster, the system holds messages in a h

ACTIVEMQ Study notes (iv)http://my.oschina.net/xiaoxishan/blog/380446 the use of native methods to send and receive messages from ACTIVEMQ. As you can see, every time you send and receive messages, you write a lot of repetitive code, and spring provides a much more convenient way for us, which is spring JMS. Let's start with an example. Includes the queue, the send and receive related spring configuration of the subject message, the code, the test. In
Message format:Establishes a message queue between two clients through peer-to-peer transmission through queues.Note: similar to the queue in the data structure, the first-in-first-outTopic message. Create a topic in the message middleware. No client can send messages to this topic to accept messages.
Note: broadcast-like methods

Procedure for using JMS
1. Create a JNDI Context

JMS Message Delivery model : The messaging mechanism is based on pull or poll (polling) .There are two " messaging models " for JMS: Peer and pub/sub.(1) Peer: Point-to-point messaging model that allows JMS clients to synchronize or asynchronously send messages through the queue (queues) virtual channel; The producer of the message is Sender and the consumer

Now try sending messages between applications through JMS.Let's take a look at the RPC solution provided by spring (in fact there are other solutions, but we have never seen anyone using it ).You need to use these two classes:· Org. springframework. JMS. remoting. jmsinvokerserviceexporter exports beans as message-based services.· Org. springframework. JMS. r
Spring provides jmstemplate a thin layer of encapsulation of native JMS APIs, which is very convenient to use. I use the JMS message Agent plugin is Apache ACTIVEMQ, it is recommended to install the latest version, because I previously installed the old version, a variety of incompatible, various bugs, The latest version of the Activemq-all-5.9.1.jar bag has a slf4j.impl bag, before it was this hole ... Add
Messagecreator callback to create a text message from a supported session object. Jmstemplate is built by passing connectionfactory references. Optionally, a default constructor and ConnectionFactory are provided and can be used to build instances of the JavaBean type (using a beanfactory or Pojo). Also, consider the base class provided by spring's Jmsgatewaysupport, which provides pre-built bean properties for the JMS configuration.

In order to understand this article, we want the reader to have a fairly solid foundation for Java programming before we begin. We will try to explain what JMS is as simple as possible, but before you can build your own programs and understand them correctly, you need to have some experience using Jndi to develop the actual application.

ActiveMQ is a high-performance messaging middleware, primarily for JMS implementations, while other languages can be used as well. Its support point to point, publish/subscribe, push-pull mode, specific reader network, here slightly.

Brief introduction of Spring JMS and ACTIVEMQ 1.1 spring JMS and ACTIVEMQThe full name of JMS is the Java message Service, whose main purpose is to deliver the message between the producer and the consumer; in the actual business scenario, when a system completes a business operation, it needs to notify the state of the operation of system B or any other system a
Application As part of the Business Process Integration Strategy, the solution requires that different systems or components do not have to understand other systems or components integrated with them. Solutions include: Eliminates point-to-point communication and message transmission; Minimum dependence on the message data structure; Centralized management of business process flows; Publish/subscribe message transmission The J2EE Application Server architecture is an event-based applicati
