Hey, everyone! I truly hope you can help.

I am well aware there have been many, many related questions asked already about this, as well as even more answers. Unfortunately, having tried all this advice I still cannot resolve this problem.

I am trying to launch a simple Java servlet in the browser, following instructions from the textbook:

Java Programming: Comprehensive Concepts and Techniques, Shelly Cashman Series, ISBN: 9781418859855.

I am aware of the advice given here to other people with this/similar problems, that servlets should preferably be written under a package, and not packageless, but I am following the textbook's guidance with this, and of course being a textbook, its method must work. I seek help with doing it in THIS method.

I have a Java servlet, called HTMLBank.java which I successfully compiled with no compilation errors. Now, according to the textbook:

1) Place the .class file into C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\ROOT\WEB-INF\classes folder. Yes, the textbook uses the default package for this and the ROOT directory of Tomcat.

2) Run the Tomcat service - it is running (shown as a green "play" arrow in right-bottom of the screen).

3) In the browser, type URL: http://localhost:8080/servlet/HTMLBank and enter it. After doing this, the following error results:

HTTP Status 404 - /servlet/HTMLBank
type Status report
message /servlet/HTMLBank
description The requested resource (/servlet/HTMLBank) is not available.

Now, I might mention that I did succeed in launching a servlet once before, but that was only if I used a package, say com.example and mapped it in the web.xml file, but as stated before, this deviates from the textbook and I need to get it to work using the default package and ROOT directory.

Here is the code of the HTMLBank.java servlet file:

import javax.servlet.*;
import javax.servlet.http.*;

import java.io.; import java.util.;

public class HTMLBank extends HttpServlet { public void init() throws ServletException {


public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
    PrintWriter out = response.getWriter();

    response.setHeader("Expires", "Tues, 01 Jan 1980 00:00:00 GMT");

        out.println("<title>Online Bank ATM Simulator</title>");
        out.println("<h1>Tester Text.</h1>");
        out.println("<body>This serves to test functioning of the servlet in browser.</body>");

public void destroy()

Here is the code of the web.xml file:

Welcome to Tomcat Welcome to Tomcat


<-- added the following for invoker servlet --> invoker org.apache.catalina.servlets.InvokerServlet

The web.xml file was modified per book guide to allow locating anonymous servlets in the default directory.

Here is the context.xml file:

<!-- The contents of this file will be loaded for each web application -->
<!-- Default set of monitored resources -->

<!-- Uncomment this to disable session persistence across Tomcat restarts -->
<Manager pathname="" />
This file was edited to enable servlet reloading, also as per book guide.

The following are paths to all the files/folders involved in this discussion:

C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\ROOT\WEB-INF\classes --> I created the "classes" folder, per book guide.

C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\ROOT\WEB-INF\classes\HTMLBank.class --> I placed the .class file into here.

C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\ROOT\WEB-INF\web.xml --> This is the location of web.xml file which was edited.

C:\Program Files\Apache Software Foundation\Tomcat 5.5\conf\context.xml is the location of the context.xml file which was edited.

So, as I said, I NEED to work the servlet without a package and from ROOT.

Please can somebody help? I greatly appreciate it!
