Deleting the Connection Factory and Stopping the Server. Messaging is a method of communication between software components or applications. A messaging system is a peer-to-peer facility: A messaging client can send messages to, and receive messages from, any other client.

Each client connects to a messaging agent that provides facilities for creating, sending, receiving, and reading messages. Messaging enables distributed communication that is loosely coupled.

A component sends a message to a destination, and the recipient can retrieve the message from the destination. However, the sender and the receiver do not have to be available at the same time in order to communicate. In fact, the sender does not need to know anything about the receiver; nor does the receiver need to know anything about the sender.

The sender and the receiver need to know only which message format and which destination to use. Messaging also differs from electronic mail email , which is a method of communication between people or between software applications and people. Messaging is used for communication between software applications or software components.

Designed by Sun and several partner companies, the JMS API defines a common set of interfaces and associated semantics that allow programs written in the Java programming language to communicate with other messaging implementations.

The JMS API minimizes the set of concepts a programmer must learn in order to use messaging products but provides enough features to support sophisticated messaging applications.

Asynchronous : A JMS provider can deliver messages to a client as they arrive; a client does not have to request messages in order to receive them. Lower levels of reliability are available for applications that can afford to miss messages or to receive duplicate messages. The JMS specification was first published in August The latest version is Version 1. The different message types are:. Text message : Represented by javax. It is used to represent a block of text.

Object message : Represented by javax. It is used to represent a java object. Bytes message : Represented by javax. It is used to represent the binary data. Stream message : Represented by javax. It is used to represent a list of java primitive values.

Map message : Represented by javax. It is used to represent a set of keyword or value pairs. In next set of posts. I will give some examples of JMS.

Very good explained, but if I want to send messages to a remote destination, where it is supossed to configure the connection for sending messages to a remote destination.

I beg you to be clearer, thanks. Look at Hornetq Spring Integration. So here we trying to achieve is this middle layer holds the load of webservices by other software queues, batches, database etc. Am a java beginner,I kindly therefore asking how to develop JMS messaging and how to create space for mobile number. A blog about Java and its related technologies, the best practices, algorithms, interview questions, scripting languages, and Python.

JMS Tutorial — Need of JMS In Java, if a person wants to send a message from one application to another in such a way that both application do not know anything about each other, even they may be deployed in separate continents with no dependency at all. Point-to-Point Messaging Domain In the point-to-point messaging domain the application is built on the basis of message queues, senders and receivers.

A messaging system is a peer-to-peer facility: A messaging client can send messages to, and receive messages from, any other client. Each client connects to a messaging agent that provides facilities for creating, sending, receiving, and reading messages. Messaging enables distributed communication that is loosely coupled. A component sends a message to a destination, and the recipient can retrieve the message from the destination. What makes the communication loosely coupled is that the destination is all that the sender and receiver have in common.

The sender and the receiver do not have to be available at the same time in order to communicate. In fact, the sender does not need to know anything about the receiver; nor does the receiver need to know anything about the sender.

The sender and the receiver need to know only which message format and which destination to use.

Asynchronous: A receiving client does not have to receive messages at the same time the sending client sends them. The sending client can send them and go on to other tasks; the receiving client can receive them much later.
