jms queue

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

sender refers to the creation and sender of the message, and is the source of the message; A message recipient is an application that receives a message and is the final destination of the message. JMS messages are processed asynchronously. A message sender can send a message without waiting for a response. The message sender sends a message to a virtual channel (topic or Queue), and the message receiver

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

Send message No matter whether a message is sent to a queue or published to a topic, the programming steps are the same. The difference is that different JMS objects are used. The specific definitions are shown in the following table: The process of sending messages is roughly divided into the following steps; 1. Get a reference to the Weblogic server context; 2. Create a connection factory; 3. Use the con

between JMS clients. Traditional messaging services generally support point-to-point communication and publish/subscribe communication in one of two communication modes. The JMS API is supported in two kinds. Point-to-Point Point-to-Point communication mode, with a central queue as the target of the publication (the managed object). One or more message producers

interact synchronously, any problem with the service hangs, which can affect the client's functioning. However, when the message is sent asynchronously, the client is separated from the service by broker, and the client is only responsible for sending the message, even if the service hangs when the message is sent, and the message is stored by the broker until the service is available and then processed.Ii. sending messages via JMSThe Java message Service is a Java standard that defines a set o

status as pending before doing business operations, this requires that the message content be determined first, and here is a workaround where the main content-that is, the information that can mark the business operation characteristics-is sent, and then the completion of the business operation after the completion of the state needs to update the full content. This is, however, a requirement to be able to determine some index-nature information before a business operation. 2. There is a need

study: asynchronous email　　Sending emails in a traditional way (as part of a synchronous request) may cause some problems. First, connecting to the email server requires a network round-trip, which may be slow, especially when the server is very busy. An overloaded email server can even temporarily make the email-Dependent Services unavailable.　　　　XA transaction support　　Another obvious problem is that email servers are generally non-transactional in nature. When the transaction is rolled back,

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

through a portable interface so that the code does not need to be modified when the implementation of the current layer changes. The administrator configures the connection factory in the Jndi namespace so that JMS clients can find them. Depending on the message type, the user will use the Queue connection factory, or the subject connection factory.The Connection Interface (connection)----Connection repres
