The Java Message Service is one of the specifications of Java EE that can be used to send asynchronous messages, and in some scenarios, can be used as a means of integration between different systems or different modules.
Can be compared to the way to integrate through the database, module A completes the logic, insert a record into the database, module B polling the database, if the corresponding records, the processing. JMS integration is actually

What happens if the phone only has real-time calls and no 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. JMS provides something l
In the previous article, the author presented an example of the process of developing Java EE applications in was CE v2.1, covering many of the new features of Java EE 5, including: Java Server Faces (JSF), Java Persistence API ( JPA), Enterprise Java Bean (EJB), and Jax-ws 2.0. As a second article in this series, this article introduces another technical--JMS (Java message Service) of Java EE 5.

MessageDrivenBean in EJB 2.0, a fundamental change to the specification is the addition of a brand new enterprise-level bean type, namely MessageDrivenBean. MessageDrivenBean is specially designed to process incoming JMS messages. For many developers, JMS is a new example, so this article will take some time to explain their understanding of JMS and their usage i

JmeterIntroduction: An excellent open-source performance testing tool.
Advantages: When you use it, you will find its many advantages. Of course, its shortcomings will also be shown.
Principles of Performance Tools:
The jmeter tool and other performance tools are exactly the same in principle. The tool consists of four parts:
(1) load generator: used to generate loads. It is usually used to simulate user behavior in multi-thread or multi

The JMeter test plan has an option called the "function test mode", which , if selected, causes the JMeter to record every sampled data returned from the server. If you select a file in the test listener, the data will be written to the file. This is useful if you try a smaller test to ensure that the JMeter is configured correctly and that your server is returni

, 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 does not necessarily run when the message is sent, and the sender does not necessarily run when the message is received; One-to-many communication: There can be multiple receivers for a message. Existing MOM systems include IBM's MQSeries, Microsoft's MSMQ, and Bea's Messageq. Without a common standard, it is difficult for these systems to interoperate
Java Message Service (JMS) Details
This article introduces the Message Service JMS in Java. Java Message Service provides the point-to-point mode and the publish-subscribe mode. These two services are described in detail in this article.
Java Message Service (JMS Java Message Services) provides point-to-point queue and publish-subscribe modes ).

Decoupling and latency processing in a request-driven environment is one of the key strategies for creating robust and Scalable Distributed applications. Many services depend solely on clusters to ensure scalability. However, when new requirements increase the complexity of applications, they often encounter problems. Although the server cluster is a basic technology that promotes scalability, it may become inefficient when all the processing is completed simultaneously. Throughput may increase
advantage is the strong type, which can be checked during compilation. The disadvantage is that it can only be based on the Java language, and the client and server are tightly coupled.
