how to run servlet

[Dayanand]

HelloServlet.java
package com.lara;

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import java.io.PrintWriter;
import java.io.IOException;
import javax.servlet.ServletException;

class HelloServlet extends HttpServlet
{
public void service(HttpServletRequest req,HttpServletResponse res)throws ServletException,IOException
{
PrintWriter out = res.getWriter();
out.println("Hai Hai WELCOME MAN");
out.close();
}
}
i developed a class file by compiling the above HelloServlet.java in the same directory
web.xml
<web-app>

<servlet>

<servlet-name>hello</servlet-name>
<servlet-class>

com.lara.HelloServlet

</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>hello</servlet-name>
<url-pattern>/callHello</url-pattern>

</servlet-mapping>

</web-app>


web.xml is also in the same directory

but when i type http://localhost:7070/app1/callHello in the IE browser,i got the below errors
HTTP Status 404 - Servlet hello is not available
type Status report
message Servlet hello is not available
description The requested resource (Servlet hello is not available) is not available.
Apache Tomcat/5.5.28


i kept HelloServlet.java,HelloServlet.class,web.xml inside webapps folder of tomcat5.5
whats the mistake in done
Thanks in advance

Why did you put those files there?
Read a tutorial that explains how to correctly package a war file so that you don't have to guess as to what goes where.
