Spring-jsf: "wiring datasource"-code looks correct, yet not working...why?

Question

The "applicationContext.xml" appears to be correctly configured to "wire" the datasource to the bean...
But, unfortunately, this simple app does not work...Error message reports "dataSource is required"...
The code/configuration I'm using reflects -- to the best of my knowledge -- the examples I've seen in books and online...
Its apparent that I am misunderstanding some fundamental concept....
Any help pointing out the critical flaw would be much appreciated!
Thanks in advance!

Answer 1

Ok, I got this fixed. Turns out it didn't like being inside a <rich:columnGroup>. Removed that and it's working.
