ah, and i've forgot to mention that in the meantime i've written a little class
to emulate the PortletPreferences stuff;
with the help of a littlte wrapper (that check if PortletServlet.
isPortletRequest (request) ) i use the real preferences or the "emuleted" one
so my still remain compatible whenever i0m in a portlet or in a web
application;
attached you can find the class that i'm using to simulate the preferences.

I guess you're talking about the Struts Bridge?
For the Struts Bridge, it currently provides only "transparent" Struts
features, meaning those that will work both
inside a standard web container and a portlet container.
Portlet specific features are easily accessible but will require to make use of
the portlet api itself as described in
Chapter PLT.16 of the Portlet API specification, see:
http://www.jcp.org/en/jsr/detail?id=168
Within an Struts Action, you can retrieve the PortletRequest as request
attribute with name: "javax.portlet.request"
And once you have the PortletRequest your can simple invoke
PortletRequest.getPreferences().

Well, having a similar/parallel feature available (for Struts) in a standard
web container would be very interesting,
something I've been thinking of myself before providing (and thereby having a
transparent solution for the Struts
Bridge), but never found time (nor actual demand) doing so.
FYI: the same "issue" is coming up for the Wicket framework for which I wrote
the Portlet support as well.
Chances are, we'll add something like the PortletPreferences for Wicket soon,
and maybe that'll be transferable to the
Struts Bridge too. But so far nothing has been written yet so time will tell...
