Introduction to JMS JMS (Java Message Service ). It is used to transmit messages between applications. Enterprise Message WebSphere MQ, SonicMQ, Microsoft Message Queue (MSMQ), ActiveMQ, Message Bean in EJB, and ESB (Enterprise Message Bus) in SOA are all Enterprise messages. Enterprise Message can be used in the following ways: Centralized Distributed Hybrid Install a Daemon program on each Client. T

Today, most computing environments are made up of different platforms rather than sticking to any platform. The Java Messaging Service (JMS), together with Extensible Markup Language (XML), satisfies the desire for this heterogeneous environment integration. This article demonstrates how to use JMS to create xml-based messages and distribute them equally to Java and non-Java applications. After several yea

messaging middleware subscription, and the systems are not affected by each other.JMS OverviewJMS is the abbreviation for the Java Message service, Java messaging, which is a specification for messages in Java EE, and Hornetq, ACTIVEMQ, and so on, are implementations of this specification. If it is an enterprise or some small system, it is an economical choice to use JMS directly, and there are some scenarios in large-scale systems that are not suita

Multi-Application system communication can be implemented based on JMS specifications Supports secure topic message transmission, transactional messages, consistent messages, and

After integration with WebSphere mq6, was 6 needs to send JMS messages to MQ in EJB (Session Bean and message Bean. The EJB itself is in the JTA transaction environment of the container, and JMS is also included in the transaction management by default. Therefore, you must select "xa support enabled" for the configuration of the connection factory. this attribute will enable

cyclically. The specific code is as follows: /*** @ Author administrator * @ description different from queue, topic implements the publish/subscribe model. In the following example, two consumers are started to listen to a topic together, then, multiple messages are repeatedly sent to the topic. * The result shows that each message is consumed by all consumers */package COM. WL. JMS; import javax. JMS. c

In the following example, two queue are created, and the sender sends a message to one queue. After receiving the message, the receiver replies a message to the other queue, then create a consumer to receive the reply message. /*** @ Author administrator * @ Description: first, create two queue. The sender sends a message to one queue. After receiving the message, the receiver replies a message to the other queue, then create a consumer to accept the reply message */package COM. WL.

JMS as the senior part of the Java EE has been shrouded in a veil of mystery, as the JMS Customizer Sun only prescribes the JMS specification, as many other sun products have been provided by several vendors to implement the specific. But as Tomcat and resin (announced at the beginning of this year all support the Java EE specification). These low-end but widely

Elements: Message queues, senders, receivers, each message is sent to a specific queue, the receiver gets the message from the queue, and the queue retains the message until it is co

In the previous article, I have already written about the PTP (point-to-point) mode of the JMS message mechanism. Today I will write about my personal publishing-subscription mode of the JMS message mechanism. Before reading the text, I would like to explain the features and differences between PTP and publishing-subscription. Features: Point-to-Point message model: this model is implemented through a Serve

Introduce an article first: http://www.javaworld.com/javaworld/jw-01-2009/jw-01-spring-transactions.html?page=1 But it's a little long, and now I've forgotten what I said. Pay attention to the comments, which refer to the content of the article is wrong. In spring, if there are both JMS operations and DB operations, there are probably three ways: 1. No use of JTA. JMS not in transaction, DB operation in tra

Recently, you want to learn about JMS and then learn about ACTIVEMQ, which is recorded here.1.ActiveMQ Introduction ACTIVEMQ Official website: http://activemq.apache.org/ (The following excerpt from Baidu Encyclopedia) ActiveMQ is the most popular, powerful, open source messaging bus that Apache has produced. ActiveMQ is a JMS provider implementation that fully supports the JMS1.1 and the Java EE 1.4 specif

I don't know that well, so this needs to be studied.JMS has 2 types of message domainsPoint-to-point mode 1.2.

Implement point-to-point message transmission of JMS Based on Tomcat + JNDI + ActiveMQ I wrote a simple JMS example. The reason for using JNDI is for universality. This example uses the common interface provided by the JMS specification and does not use the interface of a specific JMS provider, this ensures that the pr

In 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. On the basic concept of JMS (i) –JMS, we introduced the canonical JMS of message communication, and this blog post introduces an open source
