White screen for jspx files

Question

Hello,
I'm trying to deploy a basic Hello World ADF Faces Rich Client application.
Any .html files are being served up fine, but any jspx files are just giving me a white screen in the browser. For example:
http://server1/TestApp/index.html - works fine.
http://server1/TestApp/faces/testPage.jspx - gives white screen.
I'm sure I'm missing something ridiculous, but any help gratefully received.
Running JDeveloper 11.1.1.6 on WLS 11.1.1.6 using either integrated WLS or standalone managed server.
Thanks

Timo,
Many thanks, that seems to have fixed Hello World for me, although I'm unclear from your blog as to why having the bindings set should be causing me a problem, other than potentially memory utilisation.
The reason I wrote Hello World was because I couldn't get my original demo to work - specifically the one from http://www.oracle.com/webfolder/technetwork/tutorials/obe/jdev/obe11jdev/ps1/ria_application/developriaapplication_long.htm
