Recently, there is a project to use JMS, and therefore a little learning.
A messaging service means that two or more clients can communicate by sending and receiving messages (in a peer-to-peer manner). A message is a "piece" of data sent by a client to another client via a message server, either textual or numeric, and the data can include objects if the client is a Java application. Where the client does not need to run concurrently.
Reasons for usi
, 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
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.
JMS (Java Messaging Service)
JMS is a Java Message Service. JMS clients can transmit messages asynchronously through the JMS s
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
, and transactional support for businesses that need to reliably exchange messages in large quantities.
2. Message Delivery model
MS supports two types of messaging models: The Point-to-point model and the Publish/Subscribe model . These messaging models are known to be messaging domains. The point-to-point messaging model and the publish/subscribe Messaging model are often abbreviated to peer and pub/sub, respectively.
The Publish/subscribe model is designed for one-to-many (o
To understand the message-driven bean of EJB, it is inevitable to study JMS first.
In RMI, the RMI technology allows two components distributed on different physical nodes to communicate directly using method calls, in addition to Cora and WebService, they can all implement roughly the same functions. However, in the face of Systems with increasing scale and complexity, these technologies have the following shortcomings:
1) synchronous communication:
Java Message Service (JMS) for J2EEReliable message transmission on the platform is standardized. Recently released IBM WebSphere Enterprise Service Bus (ESB)The product provides some important functions that are at the core of any Service-Oriented Architecture (SOA) environment. This series has three articles describing how to integrate JMS andWebSphere ESB is used in combination to form a powerful and rel
Message Communication between Java systems is mostly based on rmi rpc and JMS rpc. Both of these two message transmission modes can communicate with each other, but in my opinion, there is a big difference between the two. First, RMI is synchronous transmission, while JMS is asynchronous transmission. The Use Cases of the two are also very different. In the system integration platform project, I have the op

The Java Messaging Service is a platform-independent API, with most MOM providers supporting

The Jmstemplate class is used to generate messages and synchronously accept messages. Like other Java EE message-driven styles, for asynchronous messages, spring also pro

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.

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

In today's projects, there are more and more distributed programs. In the SOA architecture, various services are transmitted through messages for mutual calls. Therefore, JMS, as a Java Message mechanism, should be well grasped, of course, Web services do not directly call JMS APIs.

Some Learning ExperiencesP2P mode:Concept: three roles: queue, queuesender, queuereceiver, queue, message sender, and message receiver. The sender adds a message to the queue. The receiver fetches the message from the queue. one message in the queue receives one fewer message. If multiple receivers connect to the queue, one message can only be taken by one receiver.I,The default message sending mode is deliverymode. Persistent.Method, that is, the persistence method.

First, IntroductionJMS, the Java Message Service Application interface, is an API for message-oriented middleware (MOM) in the Java platform for sending messages between two applications, or distributed systems, for asynchronous communication. The Java Messaging Service is a platform-agnostic API, and the vast majority of MOM providers support JMS.JMS allows application components to create, send, receive, and read messages based on the Java EE platform. It makes the distributed communication le

JMS is an application interface between application systems or components that communicates with each other, making it easy for us to achieve remote communication between different JVMs. RPC can do the same with remote communication, but RPC inevitably increases the degree of coupling between different systems, and JMS c
