Export your Facelets pages into PDF, PNG and SVG
Jacobus Steenkamp has an interesting article on java.net: Combine JSF Facelets and the Flying Saucer XHTML Renderer. In this article, Jacobus shows how you can use a filter and the Flying Saucer project to export a Facelets page to PDF, PNG or SVG. Pretty cool stuff if you ask me. I don't know if I'll ever have a need for it, but it's nice to know that this functionality exists.
Shameless plug: Equinox 1.7 and AppFuse 1.9.4 both include Facelets for their JSF options.
