Original link: http://haohaoxuexi.iteye.com/blog/1983532　　Spring provides a jmstransactionmanager for transaction management of JMS ConnectionFactory. This will allow the JMS application to take advantage of Spring's transaction management features. Jmstransactionmanager binds a connectionfactory/session such as a pairing to a thread from the specified connectionfactory when performing local resource transa

The cost of creating a connection from a WebSphere application Server to a Java message Service (JMS) provider, such as WebSphere MQ, is very high both in terms of time and processor requirements. To improve performance, WebSphere application Server maintains an idle connection pool that provides idle connections to applications when the application requests a connection to a JMS provider. This two-part art

The last blog introduced the ACTIVEMQ based on JMS point-to-point messaging mechanism implementation, here is another publish/subscribe method implementation. Publish subscription model It's like subscribing to a newspaper. We can choose one or more newspapers, for example: Beijing daily, People's daily. These newspapers are equivalent to topic in the release subscription model. If a lot of people subscribe to the same newspaper, we are registered in

Based on Spring+jms+activemq+tomcat, the version I'm using is as follows: Spring 2.5 ActiveMQ 5.4.0 Tomcat 6.0.30 The following learning and configuration, to achieve the basic message service functions: Send and receive. Spring provides very good support for JMS, which

deeper understanding of the needs of distributed systems. Emerging Technologies (like Java and. NET) already contains code distributions as part of their basic programming model. By doing so, these technologies have incorporated high availability and fault tolerance into messaging, while encouraging vendors offering solutions to deliver systems that consider performance on a wider range of issues. Our company has recently been asked to implement a solution for file distribution and replication

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

First of all, when doing any technical pre-Research: what will I do to clear it? Why use it? What is JMS? Java Message Service is a set of interfaces and related semantics. It defines how JMS customers can access the functions of Enterprise message generation. JMS supports two transmission modes of message-oriented middleware: point-to-point and pub/Sub ).

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

Original address: http://blog.chenlb.com/2010/01/jms-topic-durable-subscriber.html 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
