[jboss-user] [Beginners Corner] - Re: Unable to Run an EAR or WAR File

The reason why you are seeing a directory listing when you specify http://localhost:8080/HelloJSF/ is because you dont have a welcome file in your application. By default the server searches for index.jsp or index.html in the application. If it does not find this then it wil display the directory listing. If you want to disable this, you have 2 options:

1) There's a xml file where you can disable the directory listing

or 2) You can specify your welcome file in the web.xml:

<?xml version="1.0" encoding="UTF-8"?>
  | <web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
  | 	<servlet>
  | 		...
  | 		
  | 	</servlet>
  | 	<servlet-mapping>
  | 	...
  | 	</servlet-mapping>
  | 	<welcome-file-list>
  | 		<welcome-file>hello.jsp</welcome-file>
  | 	</welcome-file-list>
  | </web-app>

The other error that you are seeing (NullPointerException) when you access the hello.jsp is related to the code in your jsp. You will have to debug from the logs in server.log to figure out why thats occuring
