Need help

Hi all
I am getting the following error while running the servlet in the url
http://localhost:8080/servlet/HelloServlet
I am using Tomcat 4.1.24
HTTP Status 404 - /servlet/HelloServlet
type Status report message /servlet/HelloServlet
description The requested resource (/servlet/HelloServlet) is not available.
Apache Tomcat/4.1.24
-----------------------------
HelloServlet.java
=============
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloServlet extends HttpServlet
{
public void doGet(HttpServletRequest request,HttpServletResponse response)
throws ServletException, IOException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String docType = "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 " +
"Transitional//EN\">\n";
out.println(docType +
"<HTML>\n" +
"<HEAD><TITLE>Hello</TITLE></HEAD>\n" +
"<BODY BGCOLOR=\"#FDF5E6\">\n" +
"<H1>Hello</H1>\n" +
"</BODY></HTML>");
}
}
I have put the HelloServlet.class file inside Tomcat 4
F:\Program Files\Apache Group\Tomcat 4.1\webapps\ROOT\WEB-INF\classes directory
Please guide me where am I going wrong.
Thanks in advance

I had the same problem and was able to resolve it by uncommenting the following section in the web.xml file in the conf directory of your Tomcat installation. I am using the same version: 4.1.24

This is talked about at this website Configure Tomcat. Look at step 3 "Enable the Invoker Servlet".
