Original: http://blog.csdn.net/jiuqiyuliang/article/details/47160259In the real enterprise, the application of message communication has been very hot, and plays a special role in the enterprise application of the Java EE, so it is very necessary to study it.In brief, the basic concept of JMS (a) –JMS, we introduce the canonical JMS of message communication, we i

Queue implements the point-to-point model. In the following example, two consumers are started to listen to a queue and then send multiple messages to the queue cyclically. We still use activemq.Import javax. JMS. connection;Import javax. JMS. deliverymode;Import javax. JMS. jmsexception;Import javax. JMS. message;Impo

A message object has three parts: the message header, the message attribute, and the message data itself. It is called a payload or message body. Messages can carry important data or are only used for System Event Notifications. In most cases, messages are used as notifications and data-carrying tools at the same time. Let's talk about the message header first. Each JMS message has a set of standard message headers. Each message header is identified

1.JMS conceptThe Java Message Service provides a way for Java programs to access the Enterprise messaging system, which is composed of JMS producers, JMS Provider, JMS consumers1.1. Composition of a message(1) header (head)Each JMS message must have a message header. The hea

17) JMS: java Message Service (Java Message Service), jmsmessage JMS is a standard, just like EJB, which has many open-source and commercial implementations. The specification corresponding to ms technology is jsr914. The implementation of the Specification is called jms provider, common implementations include ActiveMQ, JBoss MQ, and IBM Websphere MQ. Its ma

allow the delivery of objects, the RPC service message is represented by the external data representation (External data representation,xdr) language.In addition, the one thing that RMI outperforms RPC or SOAP is that errors caused by object or method mismatches during program development can be discovered at compile time without waiting for the run time.###########################Note: Another article describes the difference between RPC and RMI:The RMI underlying protocol is the TCP/IP;RPC un

In recent years, developers have been able to get more extensive enterprise Message Queuing (MQ) products. Proper use of MQ technology can often improve the organization, performance, and scalability of your application. The Java Messaging Service (JMS) is part of the integration into Java EE, which enables MQ services to be used by any Java EE application. In this article (also the first part of this column series), Brian outlines some of the benefit

The full name of JMS is the Java message service, or Java messaging services. It is used primarily for messaging between producers and consumers, where producers are responsible for generating messages, and consumers are responsible for receiving messages. To apply it to the actual business requirements we can use the producer to generate a message and send it at a specific time, and the corresponding consumer will complete the corresponding business

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

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

For many friends, want to be familiar with JMS related development knowledge, online example write is also more chaotic, special manual compiled an example and server configuration, I hope you like, support my 1 JBoss Configuration Queue Message Queue Open the JBoss installation directory and locate the file Jbossmq-destinations-service.xml file under SERVER/DEFAULT/DEPLOY/JMS Add the configuration

Writing a simple JMS example, the use of Jndi is for versatility, and the example uses the generic interface provided by the JMS specification, without using the interface of the specific JMS provider, which guarantees that the program we write is suitable for any JMS implementation (ActiveMQ, HornetQ ...). What is Jnd
