Thanks for all the info.
I can't see anything obviously wrong in what you posted. I'd fire up a
debugger and step through the StandardRoot.getResource() call and check:
- You see the StandardRoot instance you expect to see
- The DirResourceSet is present
- Follow the code to see why the resource isn't looked up in your
DirResourceSet
