Business scene: A system through a queue (assuming the queue name is QueueA) to the B system to send messages, then the business adjustment, B system split into two systems B1,B2, respectively, processing different business, and each need to obtain different messages from the QueueA. In order not to change the logic of a system, a system also sends different messages to b1,b2 through a queue. B1,B2 to automatically select the message that belongs to you, you can use the message filter. The speci

Activemq is the most popular and powerful open-source message bus produced by Apache. Activemq is a JMS provider that fully supports the jms1.1 and J2EE 1.4 specifications. Although it has been a long time since the JMS specifications were introduced, however, JMS still plays a special role in today's J2EE applications. Main features: 1. Write clients in multiple

In previous articles in this series, we focused on JDBC's handling of local transactions, and this article will cover an example of a distributed transaction.Please download the GitHub source code in the following ways:git clone https://github.com/davenkin/jta-atomikos-hibernate-activemq.gitThe difference between a local transaction and a distributed transaction is that a local transaction is only used to process a single data source transaction (such as a single database), and a distributed tra

Java Message Service(The Java Messaging Service, referred to as JMS) solves this problem partly by providing a way to interact with Java EE applications or traditional systems. The universal interface collection of JMS sends or receives messages asynchronously. Receiving messages asynchronously is clearly the best choice for clients that use intermittent network connections, such as mobile phones and PDAs.

Some time ago, I was told by a colleague that there are a lot of message status for receive in the client, which can only be consumed if the JMS server or WebLogic server is fully charged. After investigation, this problem may be a bug in the WebLogic, of course, does not exclude the possibility of the specific environment. Let's take a look at the root cause of the problem, which helps us to understand more about the implementation of WebLogic

The distributed transaction about the Dubbo service framework, although it is not urgent to do, but can be discussed. I think the management of affairs should not belong to the Dubbo framework,Dubbo can only be managed by the transaction,Like JDBC and JMS are distributed resources that can be managed by transactions.Dubbo as long as the same behavior can be managed by the transaction, such as can be rolled back,The scheduling of other transactions sho

This article is a simple way to integrate spring and ACTIVEMQ, only for reference learning, with a focus on understanding the concept. 1:JMS is a standard API developed by Sun to access message-oriented middleware (MOM), and the MOM component in this article is activeMq. You can download activeMq packages to the http://activemq.apache.org/download.html Web site, It is very simple to use, after decompression directly run the D:\activemq-4.1.1\bin dir

The two message transmission modes Topic and Queue in the Jms specification are compared as follows (): 　 Topic Queue Summary Publish Subscribe messaging Publish and Subscribe messages Point-to-Point Status or not Topic data is stateless by default. By default, Queue data is stored as files on the mq server. For example, Active MQ is generally stored under $ AMQ_HOME/data/kr-store/data. You can also config

The company's technology platform in the docking of IBM MQ message middleware with a broker, messages sent to MQ have more message header information:RHF2, resulting in the reception of the message is not working properly. Record how this problem is handled here.A parameter, targetclient, is provided in IBM MQ that can be used to control whether the message header is enabled in a JMS message. When using JMS

restarts at D2, the publisher sends M6 and M7. Now S'll receive M4, M5 followed by M6 and M7 and all for future messages. i.e. S would receive all messages from M1. M7. This is the difference between durable and non-durable consuming. If S were a non-durable consumer then it would only has received M1, M2, M3 and M6, M7-not M4 and M5. i.e because the subscription is durable, S would receive every message sent to T whether the Subscriber are running or not. For non-durable topics, only messages
