Only jar you need is jsf-portlet.jar and of course your app specific jar. I have never used myface in the JSF, but is it already in JBoss? so the jBoss-face is actually myface? Because I know pretty much for sure that the jsf-lib in the web deployer directory is the sun implementation. Am I wrong? Please reply because I really want to know what's going on.
