no sir. i can see my servlet-apo executable jar file in /common/lib
how do you know my web.xml is not configured properly? i am following the book example and i dont see any difference between their example and my example.

As soon as I saw the error message, I thought that could be the issue. But it looks like some other problem. May be try with .do url-pattern. Again just a suggestion. It might not be the solution.

this is like a worst nightmare

Aliright here is how your war structure should look like
%CATLINA_HOME%/WEBAPPS/CH02<WEBAPP_NAME>
- helloworldservlet
(Place your JSPs,HTML & public resources into that folder)
- WEB-INF
(Place web.xml and nessary classes in classes folder & libraries in lib folder)
therefore if the following is you descripbed structure & you want your URL to be following http://localhost:8080/CH02/HelloWorldServlet/helloworld/hello
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<display-name>Hello World</display-name>
<description>A Hello World Web Application</description>
<servlet>
<servlet-name>HelloWorld</servlet-name>
<servlet-class>HelloWorldServlet.HelloWorldServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
<url-pattern>/HelloWorldServlet/hello</url-pattern>
</servlet-mapping>
</web-app>
and don't forget to place the HelloWorld.class under %CATLINA_HOME%/WEBAPPS/CH02<WEBAPP_NAME>/WEB_INF/classes/HelloWorldServlet folder as you have metioned it to be under HelloWorldServlet pacakage(Going by an assumption that you have already mentioned package name on the servlet source).
Hope this might help :)

WOw what in the world is that
%CATLINA_HOME%/WEBAPPS/CH02<WEBAPP_NAME>
- helloworldservlet
do i type this in the dos? if i place my class file directly in tomcat common/classes/HelloWorldServlet/ then i type in my url
http://localhost:8080/servlet/HelloWorldServlet.HelloWorldServlet
it worked but this is not an efficient way to do it.
so now let me try your example. thanks for posting but can you explain what is %catline_home?
# 7
%CATILINA_HOME% is nothing but home directory of TOMCAT server...
say something like C:\program file\tomcat 5.0\ could be the path of it
and i beg your pardon the path
%CATLINA_HOME%/WEBAPPS/CH02<WEBAPP_NAME>
is
%CATLINA_HOME%/WEBAPPS/CH02 where ch02 can be replaced by another application name
%CATLINA_HOME%/WEBAPPS/CH02<WEBAPP_NAME>
- helloworldservlet
is nothing but
%CATLINA_HOME%/WEBAPPS/CH02/helloworldservlet/
place all your JSP's & other public resources in the following folder
%CATLINA_HOME%/WEBAPPS/CH02/WEB-INF
place web.xml under this folder
%CATLINA_HOME%/WEBAPPS/CH02/WEB-INF/lib
place all your jars in the following folder
%CATLINA_HOME%/WEBAPPS/CH02/WEB-INF/classes/HelloWorldServlet
Place your HelloWorldServlet.class in the following folder.
and change your web.xml as the thing i've metioned earlier.
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<display-name>Hello World</display-name>
<description>A Hello World Web Application</description>
<servlet>
<servlet-name>HelloWorld</servlet-name>
<servlet-class>HelloWorldServlet.HelloWorldServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
<url-pattern>/HelloWorldServlet/hello</url-pattern>
</servlet-mapping>
</web-app>
Hope this doesn't confuse you further.

I guess U r not listening to what i've said....%CATLINA_HOME%\webapps\ch02\WEB-INFthis is where your folder had to be...If u r not instersted in reading posts properly...better don't post any queries as such....
# 10
i have that classes folder and lib folder under ch02/web-inf
i am listening to you rahul. i have done exatcly what you told me.
create a folder ch02
/webapps/root/ch02
create a folder for web-inf
/webapps/root/ch02/HelloWorldServlet/web-inf
put all your classes file in the classes folder in web-inf(HelloWorldServlet.class)
/webapps/root/ch02/HelloWorldServlet/web-inf/classes/HelloWorldServlet
put all your jsp files in ch02 folder
/webapps/root/ch02
put all your web.xml file under web-inf folder
/webapps/root/ch02/HelloWorldServlet/web-inf
everything i did like you said mr rahul.
# 11
ok mr rahul so i now understand what you were trying to say. you want me to make the web-inf folder in ch02. which i did. and still not working
type Status report
message /CH02/HelloWorldServlet/helloworld/hello
description The requested resource (/CH02/HelloWorldServlet/helloworld/hello) is not available.
# 12
its not
/webapps/root/ch02/HelloWorldServlet/web-inf
C:\program file\tomcat 5.0\webapps\ch02\WEB-INF
make sure you place WEB-INF folder under the application context which you are working on.
have you changed web.xml mappings to
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<display-name>Hello World</display-name>
<description>A Hello World Web Application</description>
<servlet>
<servlet-name>HelloWorld</servlet-name>
<servlet-class>HelloWorldServlet.HelloWorldServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
<url-pattern>/HelloWorldServlet/helloworld/hello</url-pattern>
</servlet-mapping>
</web-app>
as you are requesting for a pattern
http:/ /hostname:ApplicationPort /CH02/HelloWorldServlet/helloworld/hello
always make sure if you are requesting for a pattern of
http://localhost:8080/webapplicationname/XXYX..../...
your servlet mapping should be
<servlet-mapping>
<servlet-name>ServletName</servlet-name>
<url-pattern>/XXYX..../...</url-pattern>
</servlet-mapping>
