An important addition is to be added here: in the web.xml we must have 2 tags inside the < web-app> tag, those are <servlet> and <servlet-mapping> so when the article says : <servlet> <servlet-name>login</servlet-name> <servlet-class>com.onjava.login</servlet-class> </servlet> another block should be added: <servlet-mapping> <servlet-name>login</servlet-name> <url-pattern>/login</url-pattern> < !-- note it is /login not login --> </servlet-mapping> this will make it work

  I have tried this suggestion and I still could not get it to work. I am running Tomcat 4.1.24 under Windows 2000 (Professional).
  
  My web.xml file looks as follows:
  
  <?xml version="1.0" encoding="ISO-8859-1"?>
  
  <!DOCTYPE web-app
  PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
  "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
  
  <web-app>
  
  <servlet>
  <servlet-name>login</servlet-name>
  <servlet-class>com.onjava.login</servlet-class>
  </servlet>
  
  <servlet-mapping>
  <servlet-name>login</servlet-name>
  <url-pattern>/login</url-pattern>
  </servlet-mapping>
  
  </web-app>
  
  My directory structure looks as follows:
  <TOMCAT_HOME>\webapps\onjava
  =====> images (directory)
  =====> login.jsp
  =====> welcome.jsp
  =====> WEB-INF
  ==========> web.xml
  ==========> classes
  ===============> com
  ====================> onjava
  ==========================> login.class
  ==========================> login.java
  
  I have set the ServletContext in Tomcat's server.xml. My XML statement looks as follows:
  <Context path="/onjava" docBase="onjava"
  debug="1" reloadable="true"/>
  
  I was successfull in deploying an HTML and JSP application using Tomcat's administration tool and ant. I am always getting the HTTP 404 error when I am deploying servlets.
  
  Any help is highly appreciated.
  
  Thank you.
