If you follow these instructions, but checkout 2.1.3-ga4 instead, you will find portlets in the demos directory such as the jsf1-portlet and many others:
demos/bridge/jsf1-portlet/target/jsf1-portlet-2.1.3-ga4.war
All of the portlets you will find in the demos directory are working examples which use jsf 1.2. You can then deploy those to your favorite Liferay Portal, version 6.1, add one of those portlets to a page and try it out.
All of the demo portlets come with their source code in the git repo.
Hope that helps.
