problem in execution

i am preparing for scwcd.I was trying the first servlet example.I made a java file Ch1Servlet.java and DD web.xml.I performed all the steps written in the book.
project1 and tomcat both are in d directory.I compiled the program using command
javac \apache-tomcat-5.5.33\tomcat\common\lib\servlet-api.jar -d classes src/Ch1Servlet.java.then i copied the class file to web-inf/classes and xml file to web-inf.
i did everything perfectly but when i type http://localhost:8080/ch1/Serv1 Http status 404 error is coming.it says requested resource is not available.
Tomcat is running perfectly.when i point my browser to localhost:8080 home page of apahce is coming.
what could be the probelm?It is getting very frustrating.please help me.
BIG BIG Thanks in advance

You can show us your code here.. one question, did you map your servlet in web.xml?

P:S: Writing classes inside default package is discouraged, can you put your servlet class in some package..

I did not put my servlet in any package as it was the very first example in the book and.it was not put in any package.I did map my servlet in web.xml

Don't tell, Show us..
Can you post your code here? Also, web.xml..

Put your servlet in a package. The book is likely old, and not putting the servlet in a package is unlikely to work any longer.

This is web.xml file whose path is project/etc/web.xml

<?xml version="1.0" encoding="ISO-8851-1" ?>
<web-app 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/web-app_2_4.xsd"
version="2.4">

<servlet>
<servlet-name>Chapter1 Servlet</servlet-name>
<servlet-class>Ch1Servlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>Chapter1 Servlet</servlet-name>
<url-pattern>/Serv1</url-pattern>
</servlet-mapping>
</web-app>

This is Ch1Servlet.java whose path is project/src/Ch1Servlet.java

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

public class Ch1Servlet extends HttpServlet

{
public void doGet(HttpServletRequest request,HttpServletResponse response)throws IOException
{
PrintWriter out=response.getWriter();
java.util.Date today=new java.util.Date();
out.println("<html>" +
"<body>" +
"<h1 align=center>please god help me</h1>"
+ "<br>" + today + "</body>" + "</html>");
}
}

As i said i compiled the java file and put the .class file in project/classes
Then i copied web.xml in web-inf and .class file in classes.
Tomcat is running perfectly but when i type localhost:8080/ch1/Serv1 it says
Http Status 404
type status report
message
description The requested resource () is not available.
Apache tomcat /5.5.33

I repeat:

Early editions of Tomcat had a servlet called the Invoker servlet which gave limited execution capabilities to servlets not in packages. I suppose the idea was to make it easy for beginners to execute a first servlet.

This idea turned out to be a

disaster which has caused endless trouble ever since. Just accept the annoyance of learning how to use web.xml and packages - you will be glad you did.
