I am trying to deploy the Duke's Bank example form the J2EE 5 tutorial on JBoss 7.1.1. I have only used (unaltered) the source, and the standard XML configuration files for deployment, part of the exercise here is to see how I might structure a JSP based project of my own.
The exception I get is as follows:
ERROR [[jsp]] Servlet.service() for servlet jsp threw exception: java.lang.NullPointerException

I have not given any JBoss configuration files, the WAR's WEB-INF part looks like this:
$ jar tvf build/lib/dukebank-web.war
0 Sat Dec 15 22:00:12 GMT 2012 META-INF/
123 Sat Dec 15 22:00:10 GMT 2012 META-INF/MANIFEST.MF
0 Sat Dec 15 22:00:12 GMT 2012 WEB-INF/
2514 Fri Dec 14 14:29:20 GMT 2012 WEB-INF/web.xml
1348 Sat Dec 15 08:19:46 GMT 2012 WEB-INF/dukesBank.tld
7245 Sat Dec 15 08:19:46 GMT 2012 WEB-INF/faces-config.xml
2153 Sat Dec 15 08:19:46 GMT 2012 WEB-INF/tutorial-template.tld
0 Sat Dec 15 22:00:12 GMT 2012 WEB-INF/classes/...
The JSP file (main.jsp) that causes this problem is:
<f:view>
<h:form>
<jsp:include page="/template/template.jsp"/>
<center>
<h3><h:outputText value="#{bundle.Welcome}"/></h3>
</center>
</h:form>
</f:view>
The template file it includes:
<%@ taglib uri="/WEB-INF/tutorial-template.tld" prefix="tt" %>
<%@ page errorPage="/template/errorpage.jsp" %>
<%@ include file="/template/screendefinitions.jspf" %>
<html>
<head>
<title>
<tt:insert definition="bank" parameter="title"/>
</title>
<link rel="stylesheet" type="text/css" href="stylesheet.css">
</head>
<body bgcolor="#ffffff">
<tt:insert definition="bank" parameter="banner"/>
<tt:insert definition="bank" parameter="links"/>
</body>
</html>
I will refrain from coping any more files because, as I said at the start I haven't altered any of the files I have used.
Many thanks for your help, Steve
