configuring servlets on tomcat4

hi,
Can anybody guide me in configuring servlets in a new context other than the examples context ,
on tomcat4.
when i try to invoke a servlet, file not found
exception is occurring.
the structure of the web.xml is like this
<servlet>
<servlet-name>
UpdateLicense
</servlet-name>
<servlet-class>
UpdateLicense
</servlet-class>
</servlet>

--prasad

have you configured the url pattern for servlets
in web.xml??

yes i have mapped it
as
<servlet-mapping>
<servlet-name>
UpdateLicense
</servlet-name>
<url-pattern>
/ UpdateLicense </url-pattern>
</servlet-mapping>
even then iam not able to invoke it
it still gives me the file not found exception

should i be editing the web.xml or the server.xml
of the D:\jakarta-tomcat-4.0.6\conf in this case.
if yes then what should i edit ?

yes,
suppose you want to call ur servlets like:
http://servername/myapp/servlet/mypackage.myservlet
then you should uncomment the servlet maaping for "invoker" servlet in web.xml in tomcat/conf directory

Don't bother uncommenting that servlet/* mapping. It's not a 'best practice' way of invoking servlets!

the servlet mappings for each application should be in that application's web.xml. p.s. - if you tried to put a servlet mapping in server.xml, it would throw a parsing exception. They're not allowed in this file.

Is there a space between your '/' and UpdateLicense? (there shouldn't be).

Also... moving this from Servlets -> Apache/Tomcat

below is the structure of the web.xml of the application,iam trying to deploy

<?xml version="1.0" encoding="ISO-8859-1"?>
<!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>HelloWorldExample</servlet-name>
<servlet-class>test.HelloWorldExample</servlet-class>
</servlet>
</web-app>
while invoking iam using the url
http://localhost:8080/test/servlet/HelloWorldExample
the context tag in server.xml is
<Context path="/test" docBase="test" debug="0"
reloadable="true" crossContext="true"/>
i still am getting
The requested resource (/test/servlet/HelloWorldExample) is not available.

i am using tomcat4.0.6 on win nt,
heys guys help me out.

Look in your logs. Looking at your web.xml I see that some elements namely description and name are missing. I'm not sure of their order(It matters!!). I'm guessing the xml parser has thrown a parser exception during validation. If thats the case, try adding those elements in as they are mandatory and they should be in the correct order.
