Who Should Use This Book

This tutorial is intended for programmers who are interested in developing and deploying SIP applications on the Sun GlassFish Communications Server, a Java EE server that integrates a SIP servlet container. Communications Server is based on the open-source GlassFish and SailFin projects.

This tutorial is intended for the following readers:

• Java programming language developers interested in learning about how to create SIP applications.

• SIP application developers who are new to server-side Java programming language development.

• Anyone interested in how SIP applications work, and how they can be integrated in with traditional web applications and Java EE components.

This tutorial assumes you are conversant in reading Java programming language source code, and you have a basic understanding of client/server network applications.
