between "core j2ee pattern" and "petstore pattern"

[zb cong]

hello
i am now studying the petstore1.3 and the WAF architecture that is packaged in the weblogic7,i found both the web tier and the ejb tier use the similar logic structure:
in web tier:
RequestProcessor-->xxxHTMLAction-->WebClientController(that call
EjbClientController)
in ejb tier:
EjbClientController-->StsteMachine-->xxxEJBAction
but i don't know which design pattern these classes belong to?
otherwise,where can i find the article or book that can help me to map the petstore instance to pattern from the "core j2ee pattern" book.
who can help me?
thank you!
