tomcat7 404 error when deploying

Question

I'm trying to reproduce the solution given in this question but I'm still getting the same error.

Tomcat 7 keeps giving me a 404. What am I doing wrong?

This is the servlet code:

edu@ubuntu:~/ch1$ cat ch1servlet.java
package com.example;

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>HF\'s Chapter1 Servlet</h1>" +" " + "<br>" + today + "</body>" + "</html>");
    }
}

Which was compiled with:

edu@ubuntu:~/ch1/WEB-INF$ javac -classpath /usr/share/tomcat7/lib/servlet-api.jar -d classes ../ch1servlet.java
edu@ubuntu:~/ch1/WEB-INF$ ls classes/com/example/ch1servlet.class
classes/com/example/ch1servlet.class

This is the content of web.xml

edu@ubuntu:~/ch1/WEB-INF$ cat web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0"
>
    <servlet>
        <servlet-name>Chapter1 Servlet</servlet-name>
        <servlet-class>com.example.ch1servlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>Chapter1 Servlet</servlet-name>
        <url-pattern>/Serv1</url-pattern>
    </servlet-mapping>
</web-app>

Then I copied the ch1 directory to $CATALINA_HOME/webapps

edu@ubuntu:~/ch1$ cd ..
edu@ubuntu:~$ ps -aux | grep tomcat

edu@ubuntu:~$ sudo cp -rf ch1/ /usr/share/tomcat7/webapps/
edu@ubuntu:~$ ls /usr/share/tomcat7/webapps/
ch1
edu@ubuntu:~$

When I try to access 192.168.1.45:8080/ch1/Serv1

I get the infamous 404 "The requested resource (/ch1/Serv1/) is not available"

This is the version of java I'm using:

edu@ubuntu:~$ java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

I repeated quite the same process from different tutorials about a dozen of times and I always get stuck in the same point.

After copying your file and modifying web.xml you have to restart the tomcat to load the new web.xml file.

I restarted the whole server and still getting the same error. – javanoob Apr 21 '14 at 16:50

Ok this is kind of anoying.

I copied the directory in CATALINA_BASE/webapps instead of CATALINA_HOME/webapps where every single tutorial I found told me to.

It worked. I just would like to know why.

I was wondering why there was no webapps directory in CATALINA_HOME and I had to create it.
