portlet spring web flow and jsf and richfaces

Hello,
I was using spring web flow in my web project, there was no problem at all.
Now i want to use portlets, basic portlets no problems again.
I intended to have a nicest user interface and i want to use richfaces components. Whatever i do impossible to have SWF+JSF+richfaces working in my portlet project, is it possble?
At the moment i always have this trace:

Whatever i do i cant have any helloworld portlet sample project working? Does it exists? I also tried the booking-portlet-faces also impossible to get it rendering anything.
I use pluto 2.0, is it a problem?

I've read some problems with jars...

The big part of my pom: http://pastebin.com/f31948230

I'am stuck on this since a period, any help apreciate...

Thanks all.


Any link to a downloadable functional portlet (out of the box) using SWF, JSF would be apreciate too :-)
