The JMS (JAVA message Service,java messaging) API is a standard or specification of a messaging service that allows application components to create, send, receive, and read messages based on the Java EE platform. It makes distributed communication less coupled, and messaging services more reliable and asynchronous. This blog post we mainly introduce an important specification JMS in Java, because the appli

Example of publishing/subscribing to messages through JMS and example of subscribing to messages through jms Based on the previous article "Tomcat + JNDI + ActiveMQ to implement JMS point-to-point message transmission", you can easily compile a publish/subscribe message transmission example. The environment preparation is similar to this article, the main differe

Straightforward, no explanation ...... NOTE: The ConnectionFactory used with this template shocould return pooled Connections (or a single shared Connection) as well as pooled Sessions and MessageProducers. otherwise, performance of ad-hoc

June 25, 2001, the Java Messaging Service publishes the JMS 1.0.2b,2002 March 18 Java Messaging Service Release 1.1, which unifies th

When multiple systems are coupled together by synchronous invocation, reliability depends on the weakest party system. asynchronous invocation can enhance the robustness of a system. Of course, not all cases are suitable for asynchronous invocation, or that sentence, can be asynchronous place, as far as possible asynchronous. Asynchronous message, like a mailbox system, we put the letter into th

1. Basic concepts of JMS Java Message Service (JMS) is a Java Message Service. It provides standard interfaces for generating, sending, and receiving messages, simplifying the development of enterprise applications. It supports two message communication models: point-to-point (P2P) model and pub/Sub Model. The P2P model specifies that a message can only have one receiver; pub/subThe model allows a message t

Talk about Async:Asynchronous message, like a mailbox system, we put the letter into the mail bucket, the postman will according to the above address, sent to the place where the letter to go. The mailbox and letter formats are defined by the Post office, such as a mailbox that needs a cut-off message, an address, a zip code, and so on. The specific

In JMSAPI, ConnectionFactory and Destination can be both managed objects created by the

Research on the Distributed System Based on JMS Message Middleware (2); Research on jms Message Middleware In the previous article, we solved the communication problem between subsystems and ran a model project. Here we need to implement the server program in detail. We run Spring on the server, use the IoC container of Spring to manage all the Service components, and then follow the received

Here we will give a simple demo of how to implement distributed transactions using message-oriented middleware, it also allows you to gain experience and think about distributed transactions in practice. 1.
