ActiveMQ Introduction

ActiveMQ is a messaging bus and helps in building Event based systems.It supports JMS which is a JavaEE based feature. In this tutorial, we will look into how to install and start a ActiveMQ server and a small program to create topic and consume topic over the message bus. We will also look into the ActiveMQ web front end where we can see what is happening in the message bus. This tutorial is based on windows but pretty much similar steps can be followed for Linux.
