running a servlet from a new web application

[gaurav abbi]

hi all,
i'm trying to run a servlet from my own web application
but its giving me following error

HTTP Status 404 - /myLearning/servlet/HelloServlet

--------------------------------------------------------------------------------

type Status report

message /myLearning/servlet/HelloServlet

description The requested resource (/myLearning/servlet/HelloServlet) is not available

i'm giving the following path
http://localhost:8080/myLearning/servlet/HelloServlet

and my class file for servlet is placed in this dir structure
E:\gaurav\j2ee\apache-tomcat-5.5.20\webapps\myLearning\WEB-INF\classes

i've made the corresponding enteries in web.xml file placed here
E:\gaurav\j2ee\apache-tomcat-5.5.20\webapps\myLearning\WEB-INF

and the file is:
<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app

"http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"

</servlet>
<servlet-mapping>
<servlet-name>HelloServlet</servlet-name>
<url-pattern>/HelloServlet</url-pattern>
</servlet-mapping>
</web-app>


but if i put my class file in ROOT structure
E:\gaurav\j2ee\apache-tomcat-5.5.20\webapps\ROOT\WEB-INF\classes
and make the corresponding enteries in web.xml file, it runs fine

i'm not able to figure out whats going wrong.

please reply.

I am guessing you are using an old text or tutorial that depends on the dreaded Invoker servlet being configured on your system.

Your web.xml shows that your HelloServlet is not in a package - to avoid future hard to diagnose problems, put ALL classes involved in servlets or JSP in packages and place compiled class files accordingly.
