Implement point-to-point message transmission of JMS Based on Tomcat + JNDI + ActiveMQ I wrote a simple JMS example. The reason for using JNDI is for universality. This example uses the common interface provided by the JMS specifi

Background When thinking about messaging solutions, you might think of a system that integrates two different applications through a remote message invocation mechanism. In general, this coupling is often used for distributed entities that do not communicate frequently and for data transfer volumes. A more classic example is a homogeneous interface to a heterogeneous backend and portal that assigns the bac

Lookup ("Java:comp/env/queue/connectionfactory"); //Create a queue connectionQueueconnection Queconn =confactory.createqueueconnection (); //Create a queue sessionQueuesession quesession = queconn.createqueuesession (false, Session.auto_acknowledge); //Create a queue receiverQueueReceiver Quereceiver =quesession.createreceiver (queue); //Start the connectionQueconn.start (); //receive a messageTextMessage message =(

JMS-based Active MQ message storage, jmsmqI. Message Storage Methods ActiveMQ supports persistent messages and non-persistent messages in JMS specifications. Persistent messages are usually used to ensure that messages are consumed by consumers regardless of whether the consumers are online or not. After the

mechanic is what you want to use. for example, you may consume messages from one queue andThen put messages on a different queue using the same JMSSession. the transacted session will treat all consumed and produced messages as part of a single transaction and will commit or rollback all messages at once. message acknowledgement on a non-transacted session will "commit" consumed messages independentlyOf th

message. The message consumer can consume the message only within the validity period. The default value is 0, indicating that the message never expires. You can set it in the following way:Producer. settimetolive (3600000); // valid for 1 hour (1000 ms * 60 seconds * 60 minutes)5) jmspriorityThe priority of the

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
