Deploying a simple servlet on Tomcat.

Edit: Thanks, solved.

Hi, I'm having problems deploying a very simple servlet on Tomcat 5.5. When I direct my browser to the expected URL, Tomcat just spits back a blank "Directory Listing for /" page, and I'm not seeing anything helpful in the logs.

I'm wondering if the problem is that I have not included any .html files in my webapp ... but I don't understand why I would need to, or what I would have to put in it.


Compiles fine.
Servlet Code:
public class HelloWorldExample extends HttpServlet {


public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
{
   response.setContentType("text/html");
   PrintWriter out = response.getWriter();
   out.println("");
   out.println("");
   out.println("");
   out.println("See my first demo work!");
   out.println("");
   out.println("");
}
}

The URL I type into my browser is
http://localhost:8080/Hello. No dice :(

Web.xml config:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE web-app (View Source for full doctype...)>
<web-app>
 <display-name>Hello v2</display-name>
 <description>Hello Demo</description>
 <servlet>
  <servlet-name>Hello</servlet-name>
  <servlet-class>HelloWorldExample</servlet-class>
 </servlet>
 <servlet-mapping>
  <servlet-name>Hello</servlet-name>
  <url-pattern>/Hello</url-pattern>
</servlet-mapping>
</web-app>

As I understand it, this configuration should allow me to access my servlet by http://localhost:8080/Hello

.war layout:
demo/
WEB-INF/web.xml
WEB-INF/classes/HelloWorldExample.class
WEB-INF/classes/HelloWorldExample.java


I've read the tomcat docs and "Tomcat - The Definitive Guide" (O'Reilly). Many thanks if anyone could offer me some pointers.
