Warum lädt mein Spring-Webprojekt beim Start nicht die richtige Seite?

Question

Titel sagt alles wirklich. Ich habe ein kleines Spring-Web-Projekt, das beim Start in meinem Browser redirect.jsp öffnen soll. Dies sollte mich durch einen Standardcontroller zu home.jsp schicken. Das Problem ist, es tut es nicht. Stattdessen öffnet es automatisch eine Standardindexseite in meinem Browser. Die angezeigte Indexseite existiert in meinem Projekt nicht, hat den Titel "Starting Page" und zeigt nur eine Kopfzeile mit "Hello World". Seltsamerweise ist die URL in meinem Browser nur localhost:port/projectrootfolder und nicht localhost:port/projectrootfolder/home.htm oder etwas ähnliches.

Mein redirect.jsp

<%-- 
Views should be stored under the WEB-INF folder so that 
they are not accessible except through controller process. 

This JSP is here to provide a redirect to the dispatcher 
servlet but should be the only JSP outside of WEB-INF. 
--%> 
<%@page contentType="text/html" pageEncoding="UTF-8"%> 
<% response.sendRedirect("/home.htm"); %>
