Apache Qpid JMS client for AMQP 0-9-1/0-10 is an implementation of JMS specification 1.1. It utilises an AMQP transport layer for the performing of messaging operations. The client is intended to be used for writing of JMS compatible messaging applications. Such applications can send and receive messages via any AMQP-compatible brokers like RabbitMQ, Apache Qpid Broker for Java which supports AMQP protocols 0-8, 0-9, or 0-9-1. The Client hides the details of AMQP transport implementation behind the JMS API. Thus, the developers need only to be familiar with JMS API in order to use the client. However, the knowledge of the basic concepts of AMQP protocols can help developers in writing reliable and high-performant messaging application. This book documents the behaviour of the Apache Qpid JMS client for AMQP 0-9-1/0-10 when used with the AMQP protocols 0-8, 0-9, and 0-9-1 only. For behaviour when using the Client with AMQP 0-10 protocol, please refer to Using AMQP 0-10 with the Apache Qpid JMS client for AMQP 0-9-1/0-10.
