Simple Apache Coyote Tomcat Java-app architecture diagram

view story

http://superuser.com – After a hour(!) googling i don't find any IMAGE what shows the architecture of the next "components". apache coyote tomcat java-app (in my case Liferay, but this is probably doesn't matter) I know nothing about tomcat/java/servlets and so on... Need only an SIMPLE (really SIMPLE) image, where is shown ALL above compoments and their relationships. (Best, what shows how requests/responses are handles). The best image what i find, is the next from: http://www.akadia.com/download/soug/tomcat/html/tomcat_apache.html but doesn't shows the "coyote". Really need read 100+ pages to understand (HowTos)
