How to read this document ?

You are currently reading the introduction that gives an overview of the JOnAS world. For the impatients who want to start playing with JOnAS without going through the details of all steps, you can try the next chapter (the chapter called Quick Start). Note that this Quick Start requires some skills like downloading and uncompressing an archive or setting environment variables. For those who are not familiar with those tasks, you should better read sequentially the tutorial from the chapter called Getting and installing the software that details every single step.

the chapter called Getting and installing the software and the chapter called Configuring your environment help you setting up all the software needed for a complete J2EE environment including Web, Servlets and EJB servers. This part also describes how to configure the software for a distributed environment (servers running on separate physical machines).

the chapter called Getting started with JOnAS is a quick reference to JOnAS and guides you through the most common tasks you will have to perform.

The remaining chapters are specific to EJB applications development. Each chapter treats a different programming concept and illustrates it with a specific example. The Alarm application is a "put it all together" example that gives an overview of a complete application using JOnAS.
