servlets and myjavaserver

[Alan]

I have a problem and not I don´t know where I have the mistake.
I have a count in myjavaserver and I am trying to test a servlet but I don´t obtain good results the page always returns me "404 not found".

in the root of my directory I have this:
/WEB-INF/classes/com/bloodredsun/servlet/

inside of this I have this file:
ExampleServlet.class
this servlet has that:
response.getWriter().println("<b>hello</b>world!!!")"

in web.xml I have this:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!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>ExampleServlet</servlet-name>
    <servlet-class>com.bloodredsun.servlet.ExampleServlet</servlet-class>
  </servlet> 
  <servlet-mapping>
    <servlet-name>ExampleServlet</servlet-name>
    <url-pattern>/ExampleServlet.do</url-pattern>
  </servlet-mapping> 
<session-config>
    <session-timeout>
            30
        </session-timeout>
  </session-config>
  <welcome-file-list>
    <welcome-file>
            index.jsp
        </welcome-file>
    <welcome-file>
            index.html
        </welcome-file>
    <welcome-file>
            index.htm
        </welcome-file>
  </welcome-file-list>
</web-app>

When I write this link:

http://www.myjavaserver.com/~afluben...mpleServlet.do

this message appear:
The requested URL /~aflubenov/ExampleServlet.do was not found on this server.
Do you know what is happening?

<servlet-mapping>
<servlet-name>ExampleServlet</servlet-name>
<url-pattern>/ExampleServlet.do</url-pattern>
</servlet-mapping>

i n place of this mapping u try
<servlet-mapping>
<servlet-name>ExampleServlet</servlet-name>
<url-pattern>/servlet/ExampleServlet</url-pattern>
</servlet-mapping>

it will work
