web.xml tags

[Shweta R Dhaneshwar]

Hi,
I am new to web programing.Can anyone tell me difference between these two in the web.xml

 In the <servlet> element, 
        <servlet-name>
            status
        </servlet-name>
        <servlet-class>
    org.apache.tomcat.servlets.StatusServlet
        </servlet-class>
 
and in <servlet-mapping> element, 
        <servlet-name>
            status
        </servlet-name>
        <url-pattern>
            /org.apache.jserv.JServ
        </url-pattern>

It defines the mapping between the name client uses ( /org.apache.jserv.JServ ) and the actual servlet class (org.apache.tomcat.servlets.StatusServlet )

<servlet-name> tag : You will use the name (status in your case) defined here within other parts of the DD

So when a request comes in,
1.the container finds <url-pattern> that has /org.apache.jserv.JServ.
2.then container gets the <servlet-name> ( status )
3.container looks in the <servlet> tag for <servlet-name> ( status )
4. then it uses the actual <servlet-class>

hope this helps
