The JMS (Java Messaging Service) is a technical specification for message-oriented middleware on the Java platform, which facilitates the message exchange of Java applications in the messaging system, and by providing standard generation, sending, receivingTo simplify the development of enterprise applications, ACTIVEMQ is a concrete implementation of this specification.The JMS queue message delivery process is as follows:The topic message delivery pr

Writing a simple JMS example, the use of Jndi is for versatility, and the example uses the generic interface provided by the JMS specification, without using the interface of the specific JMS provider, which guarantees that the program we write is suitable for any JMS implementation (ActiveMQ, HornetQ ...). What is JndiJNDI (Java naming and directory Interface) is a standard specification, similar to a specification such as JDBC,JMS, that provides dev

Tags: activemq debug C ++ library debuggingI have previously written an article about the activemq-CPP compilation method. At that time, the release version was compiled and debugging was inconvenient. So I re-compiled it. After multiple tests, we found that activemq only has four dependent libraries.That is ws2_32.lib; apr-1.lib; mswsock. Lib; libactivemq-cppd.l

ACTIVEMQ This open source messaging server provides multi-lingual support, in addition to the General Java client, you can also use the C + +, PHP, Python, JavaScript (Ajax) and other languages to develop the client. Recently, because of project needs, we need to provide PHP and Python theme subscription client. Here, as a summary, lists the simple installation and use of the client for both languages.For PHP and Python, you can communicate with the m

We've learned how to deploy ACTIVEMQ in the front,We know that the task queue can be viewed through a management background in ACTIVEMQ.TodayUsing PHP to manipulate ACTIVEMQ, we can use a third-party extension.Download:require fusesource/stomp-php:2.0.*Then create a new test.php:require __DIR__.‘/vendor/autoload.php‘; //引入自动加载的文件$connect = new \FuseSource\Stomp\Stomp(‘tcp://10.211.55.13/:61613‘);$connect->c

Brief Introduction Actual combat one, the actual combat two introduced the basic concept and the configuration way of ACTIVEMQ. This article introduces a way to use spring to send, consume topic, queue type messages. Do not understand the topic and queue of Google. As shown in the illustration, topic and queue represent a topic and a queue message channel respectively. Topicmessageproducer sends messages to topic, Topicconsumera and Topicconsumerb

In a real-world program, you can find factory through Jndi lookups, which completely avoids associating specific JMS implementations. a

DeliveryMode refers to whether messages that were not consumed in the original queue or subject remain when the ACTIVEMQ is restarted I have done the following tests myself through the code, and the test steps and results are as follows: Create the producer and set the producer DeliveryMode to persistent and run producer Restart ACTIVEMQ before the message is consumed by consumer

RabbitMQ, ACTIVEMQ, and ZEROMQ are excellent messaging middleware, but which of our options is better for our project? Many developers face this annoyance. Below I will make a comparison of the three message middleware, after you have seen it.RABBITMQ is a leading implementation of the AMQP protocol that implements the broker architecture, meaning that messages can be queued on the central node before they are sent to the client. This feature makes RA

ActiveMQ-cpp client application exited abnormallyThe author uses ActiveMQ as the server for message distribution in the system. The Java Web program reads the database real-time records as the Producer, and the receiving end is the client program developed by C ++ Builder. It is resident in the lower right corner of the client, the pop-up window displays real-time messages. During the test, it is found that

When activemq is used in Android projects, an error is reported. The reason should be: the class you are about to use calls another class, and this class calls other classes. This relationship may have many layers. During this call, the missing package of a class will cause the above error. Cannot be called.
