I have searched jsf2 + ejb3 tutorial in google for a while, but I couldn't found an example or tutorial base on JBOSS.
I'd be very appreciated if anyone can tell me a link and example on this.
pick any EE 6 tutorial (e.g. http://netbeans.dzone.com/articles/develop-java-ee-6-app-jsf2)
Once you get as far as a deployment archive (EAR or WAR) the appserver really doesn't matter that much. For JBoss, just drop it in JBOSS_HOME\server\default\deploy and start it up.
