Tutorial for Tomcat Beginners!!

[David]

Hi guys,
I am a complete newbie to hosting a webserver.
I just installed the tomcat and would very much want to learn more about
it.
 
I cannot find any tutorials links on tomcat from the Tomcat main site at
all.
 
Does anyone know of any online tutorial website where I can learn how to
use Tomcat as my webserver ?
 
P/S: I am a competent Java programmer but have no XML know-how. Is this
going to be a problem ?
 
Regards
David
