Class IndexerServlet

java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

com.googlecode.fascinator.portal.servlet.IndexerServlet

All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class IndexerServlet
extends javax.servlet.http.HttpServlet

Introduction

This Servlet is mainly just a shell, because its doGet() and doPost() methods are empty. We are relying on Tapestry to do the true web server work later. What we do want here however is to instantiate anything we require to start with the server. Because Tapestry services are instantiated and injected on demand, we can't rely on them for some of our system components.
