1. Introduction

This User Guide covers the Virgo Server for Apache Tomcat (VTS), the Virgo Jetty Server (VJS) and the Virgo Kernel (VK), although it emphasises the VTS since that is likely to apply to more users.

1.1 A Note for Virgo Kernel Users

Virgo Kernel users can be reassured that the majority of the information in this Guide is directly applicable to the Virgo Kernel and they can simply ignore the web-related sections.
