Can't get servlets to work in Tomcat 6

I am a Java beginner and trying to make my first example work.

I have installed Tomcat6.0 and using Eclipse on Windows.

I have placed HelloWorld folder in webapps. In WEB-INF have placed classes folder and web.xml.

When I place this as the URL: http://localhost:8080/HelloWorld/HelloWorld

I get the following error:

HTTP Status 404: The requested resource () is not available.

When I try http://localhost:8080 it works fine and gives access to Tomcat's home page and I can execute the example from there.

My web.xml is:

<?xml version="1.0" encoding="ISO-8859-1"?>
<!-- <!DOCTYPE web-app
 PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd"> -->

<web-app>
    <servlet>
        <servlet-name>Hello</servlet-name>
        <servlet-class>HelloWorld</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>Hello</servlet-name>
        <url-pattern>/HelloWorld</url-pattern>
    </servlet-mapping>
</web-app>

My HelloWorld.java is :

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class HelloWorld extends HttpServlet { 
    public void doGet(HttpServletRequest request, HttpServletResponse response)
                throws ServletException,IOException {

        response.setContentType("text/html");

        PrintWriter pw = response.getWriter();
        pw.println("<html>");
        pw.println("<head><title>Hello World</title></title>");
        pw.println("<body>");
        pw.println("<h1>Hello World</h1>");
        pw.println("</body></html>");
    }
}

Please help. I am stuck on this from two days. EDIT: Solved the problem. Thanks. I added HelloWorld in web.xml and it worked. Thanks for the help.

What you need to have for this to work is the following:

1) Create a folder HellowWorld inside $CATALINA_HOME/webapps directory

2) Create a folder named WEB-INF inside the HellowWorld directory and place in the web.xml exactly as you have given it to us.

3) Place HellowWorld.class (not the .java) inside WEB-INF/classes (exactly as you have given it to us)

4) Then Start your tomcat server that listens on port 8080 (preferable a clean installation).

5) Call http://localhost:8080/HelloWorld/HelloWorld (directly from browser's url or from a form with action=get)

6) Now it should work fine (works on my tomcat7)

If you have anything different in your configuration then that is what causes the problem.

Please put HelloWorld folder outside the webapps folder.
