Introduction

Purpose

This part of the diploma thesis gives an in-depth introduction into several technologies used while developing the software system. Additionally the software system and its components will be explained.

As a prerequisit, everyone that is not quite familiar to J2ME and J2EE technologies should take the time to read section Technology Overview because this will simplify the understanding of each following section.

Scope

The result of this diploma thesis will be a CD-ROM as described in the preface of this diploma thesis.

Definitions, Acronyms and Abbreviations

This document uses definitions based upon those specified in RFC 2119.

Table 4.1. Specification Terms

Term	Definition
MUST	The associated definition is an absolute requirement of this specification.

Overview

The following chapter introduces basic J2EE and Web Service principles. This chapter isn't meant as a complete overview of all the various technologies, it is rather meant to help people understand why a specific kind of techonology is important in the context of iChilli™.

The chapter System Overview gives an overview about the iChilli™ server system, additionally this chapter includes a very detailed section about the PersonalChilli system and its various sub-componets. Finally a brief overview about the application deployment infrastructure will be given.
