JMS Tutorials

In this detailed Resource page, we feature an abundance of JMS Tutorials!

The Java Message Service (JMS) API is a Java message-oriented middleware API for sending messages between two or more clients. It is an implementation to handle the producer–consumer problem. JMS is a part of the Java Platform, Enterprise Edition (Java EE), and was defined by a specification developed at Sun Microsystems, but which has since been guided by the Java Community Process. It is a messaging standard that allows application components based on Java EE to create, send, receive, and read messages. It allows the communication between different components of a distributed application to be loosely coupled, reliable, and asynchronous.

Elements

The following are JMS elements:

• JMS provider
  An implementation of the JMS interface for message-oriented middleware (MOM). Providers are implemented as either a Java JMS implementation or an adapter to a non-Java MOM.
• JMS client
  An application or process that produces and/or receives messages.
• JMS producer/publisher
  A JMS client that creates and sends messages.
• JMS consumer/subscriber
  A JMS client that receives messages.
• JMS message
  An object that contains the data being transferred between JMS clients.
• JMS queue
  A staging area that contains messages that have been sent and are waiting to be read (by only one consumer). Contrary to what the name queue suggests, messages don’t have to be received in the order in which they were sent. A JMS queue only guarantees that each message is processed only once.
• JMS topic
  A distribution mechanism for publishing messages that are delivered to multiple subscribers.

Models

The JMS API supports two distinct models:

• Point-to-point
• Publish-and-subscribe

Provider implementations

To use JMS, one must have a JMS provider that can manage the sessions, queues and topics. Starting from Java EE version 1.4, a JMS provider has to be contained in all Java EE application servers. This can be implemented using the message inflow management of the Java EE Connector Architecture, which was first made available in that version.

The following is a list of common JMS providers:

• Amazon SQS’s Java Messaging Library
• Apache ActiveMQ
• Apache Qpid, using AMQP
• IBM MQ (formerly MQSeries, then WebSphere MQ)
• IBM WebSphere Application Server’s Service Integration Bus (SIBus)
• JBoss Messaging and HornetQ from JBoss
• JORAM from the OW2 Consortium
• Open Message Queue from Oracle
• OpenJMS from the OpenJMS Group
• Oracle WebLogic Server and Oracle AQ
• RabbitMQ from Pivotal Software

JMS Tutorials – Getting Started

Simple examples based on various JMS providers

Apache ActiveMQ

• Apache ActiveMQ “Hello World” Example
  In this example, we shall show you how to make use of ActiveMQ as a message broker for exchanging messages between applications connected via a network.
• Apache ActiveMQ Best Practices Tutorial
  In this tutorial, you will learn how to develop a few Java applications which integrate ActiveMQ to send and receive messages to and from destinations. If you already know how to install and configure ActiveMQ, you can skip the first four chapters.
• Apache ActiveMQ SSL Example
  In this example, I will demonstrate how to configure an AMQ broker to support SSL and how to create a simple Java application which connects to it securely.
• Apache ActiveMQ File Transfer Example
  In this example, I will build two simple AMQ applications which will transfer files from one location to another
• Apache ActiveMQ Distributed Queue Tutorial
  In this article, I will demonstrate how to utilize a distributed queue within a group of AMQ brokers.
• Apache ActiveMQ Monitoring Tutorial
  In this example, I will explain how to monitor an AMQ server.
• Apache ActiveMQ Failover Example
  In this example, I will demonstrate how to configure a group of AMQ brokers to make the system fault-tolerant.
• Apache ActiveMQ Load Balancing Example
  In this example, we will demonstrate how to build a load-balanced AMQ client application.
• Apache ActiveMQ BrokerService Example
  In this example, we will see how we embed a broker inside a connection and the usage of ActiveMQ BrokerService API.
• Apache ActiveMQ Advisory Example
  In this tutorial we will see how a consumer gets notified whenever a message is consumed.
• JMS TextMessage Example
  In this article, we will look into examples of simple as well as XML based TextMessage.
• JMS QueueBrowser Example
  In this article, we will see an examples of QueueBrowser object.
• JMS Client Example
  In this article, we will see several examples of JMS Clients.
• JMS Topic Example
  In this article, we will see some examples of JMS Topic.
• JMS Queue Example
  In this article, we will see some examples of JMS Queue.
• JMS MessageListener Example
  In this article, we will see what is a MessageListener and how we can use it to receive messages.
• JMS Message Types Example
  In this example we are using activeMq so our pom.xml will have dependencies related to spring as well as activeMq.

JBOSS

• Java JMS “HelloWorld” on JBoss Example
  In this article, I am going to show a simple “Hello World” example using JBoss Messaging.
• Simple JMS example on JBoss 5.1
  In this example we shall show you how to create a simple hello World example in JMS, using JBoss 5.1. JMS is a very popular API standard for messaging, and most messaging systems provide a JMS API.
