After some minor prodding in ##wicket on irc.freenode.org, Daniel Kaplan just posted a short tutorial on writing a Wicket based Facebook applications - and when I say short, I mean really short - 4 classes and less than a printed page.
Whilst the facebook-java-api library handles all the "hard work" of authenticating and interacting with the Facebook REST API, Daniel's example shows how simple and clean it is to do the "application" side of things.
Most excellent.
Update: Whilst it was only 3 classes, one was missing. Daniel has now updated the wiki.
Hello !
Robert - I just mentioned it to Daniel and he's updating the wiki page with
the missing class.
