NullPointerException in TilesAccess.getContainer when accessing app

[Andrey Botalov]

I build web app using Servlets, JSP and I think Tiles will be a good 
idea to use. I use Servlets 3.0, Tiles 3.0.1

Currently when I run app and go to "/products", I get the following 
stack trace in Eclipse console:
https://gist.github.com/3314105
Fragments of app that may be relevant are:
https://gist.github.com/3314068 (gist.github allows only \, not / in 
filenames)

How do I solve it?
