Chapter 1. Overview AMQ Core Protocol JMS is a Java Message Service (JMS) 2.0 client for use in messaging applications that send and receive Artemis Core Protocol messages. AMQ Core Protocol JMS is part of AMQ Clients, a suite of messaging libraries supporting multiple languages and platforms. For an overview of the clients, see AMQ Clients Overview . For information about this release, see AMQ Clients 2.9 Release Notes . AMQ Core Protocol JMS is based on the JMS implementation from Apache ActiveMQ Artemis . For more information about the JMS API, see the JMS API reference and the JMS tutorial . 1.1. Key features JMS 1.1 and 2.0 compatible SSL/TLS for secure communication Automatic reconnect and failover Distributed transactions (XA) Pure-Java implementation 1.2. Supported standards and protocols AMQ Core Protocol JMS supports the following industry-recognized standards and network protocols: Version 2.0 of the Java Message Service API Versions 1.0, 1.1, 1.2, and 1.3 of the Transport Layer Security (TLS) protocol, the successor to SSL Modern TCP with IPv6 1.3. Supported configurations AMQ Core Protocol JMS supports the OS and language versions listed below. For more information, see Red Hat AMQ 7 Supported Configurations .

Terms and concepts This section introduces the core API entities and describes how they operate together. Table 1.1. API terms Entity Description ConnectionFactory An entry point for creating connections. Connection A channel for communication between two peers on a network. It contains sessions. Session A context for producing and consuming messages. It contains message producers and consumers. MessageProducer A channel for sending messages to a destination. It has a target destination. MessageConsumer A channel for receiving messages from a destination. It has a source destination. Destination A named location for messages, either a queue or a topic. Queue A stored sequence of messages. Topic A stored sequence of messages for multicast distribution. Message An application-specific piece of information. AMQ Core Protocol JMS sends and receives messages . Messages are transferred between connected peers using message producers and consumers . Producers and consumers are established over sessions . Sessions are established over connections . Connections are created by connection factories . A sending peer creates a producer to send messages. The producer has a destination that identifies a target queue or topic at the remote peer. A receiving peer creates a consumer to receive messages. Like the producer, the consumer has a destination that identifies a source queue or topic at the remote peer. A destination is either a queue or a topic . In JMS, queues and topics are client-side representations of named broker entities that hold messages. A queue implements point-to-point semantics. Each message is seen by only one consumer, and the message is removed from the queue after it is read. A topic implements publish-subscribe semantics. Each message is seen by multiple consumers, and the message remains available to other consumers after it is read. See the JMS tutorial for more information. 1.5. Document conventions The sudo command In this document, sudo is used for any command that requires root privileges. Exercise caution when using sudo because any changes can affect the entire system. For more information about sudo , see Using the sudo command . File paths In this document, all file paths are valid for Linux, UNIX, and similar operating systems (for example, /home/andrea ). On Microsoft Windows, you must use the equivalent Windows paths (for example, C:\Users\andrea ). Variable text This document contains code blocks with variables that you must replace with values specific to your environment. Variable text is enclosed in arrow braces and styled as italic monospace. For example, in the following command, replace <project-dir> with the value for your environment: USD cd <project-dir>

Commands:
cd <project-dir>
