JMS API

We are using the following steps for developing a J2EE application to use the JMS API directly for asynchronous messaging. We will list all the common APIs that are predominately used in JMS. 1)       Import JMS packages: – A J2EE application that uses JMS starts with several import statement. Eg: – import javax.jms.*;       //JMS interfaces […]

Developing Robust JMS Applications

The JMS API allows two different ways to achieve various kinds and degrees of reliability. They are, Using Basic Reliability Mechanism Using Advanced Reliability Mechanism. Using Basic Reliability Mechanism. The below mechanisms are used for extracting the reliable message delivery. A)    Controlling message acknowledgment:- It helps to define different levels of control over message acknowledgment. […]

Simple JMS Client Application

The JMS client applications are simple and standalone programs that run outside the server as class files. For the JMS application client ,let’s create three different basic tasks. They are, Creating connection and a session Creating message producers and consumers Sending and receiving messages Here we are using J2EE platform for the working of JMS […]

JMS Programming Model

The basic building blocks of JMS programming models are, Administered Objects Connections Session Message Producers Message   Administered Objects JMS application consists of two parts. A)    Connection factories B)    Destinations The above two objects are used to maintained administratively rather than programmatically. The management of these objects with other administrative tasks is totally different from […]

JMS Interview Questions

It is according to the specification that the message sent should be received in the same format. A non-java client cannot receive a message in the form of java object. The provider […]

Developing a JMS program

In this article we’ll learn on how to develop a JMS program. The step by step explanation is listed below. A typical JMS program goes through the following steps to begin producing and consuming messages. 1. Look up a ConnectionFactory through JNDI. 2. Look up one or more Destinations through JNDI. 3. Use the ConnectionFactory to create a […]

JMS Overview

This section gives an overview of JMS.A JMS application is comprised of the following elements: JMS clients. Java programs that send and receive messages using the JMS API. Non-JMS clients. It is important to realize that legacy programs will often be part of an overall JMS application and their inclusion must be anticipated in planning. […]

JMS – Objectives

The  Java Message Service specification 1.0.2 states that JMS is a set of interfaces and associated semantics that define how a JMS client accesses the facilities of an enterprise messaging product. Prior to JMS, each MOM vendor provided application access to their product through a proprietary API, often available in multiple languages, including the Java […]

JMS Architecture

JMS architecture is a widely acclaimed architecture in the messaging world.The Java Message Service (JMS), which is designed by Sun Microsystems and several other companies under the Java Community Process as JSR 914, is the first enterprise messaging API that has received wide industry support. The Java Message Service (JMS) was designed to make it easy […]
