All the tags in these XMLs are supposed to be in lowercase, and hence is not a tag as per the DTD. It should be used in lowercase as .

Other tags too should be in lowercase.
It should solve the issues like
SEVERE: Error parsing XML: hibernate.cfg.xml(3) Document is invalid: no grammar found.

I too had the same error but I could solve it. The tutorial misses doctype tag in both hbm and config files. To solve the above problem, add the following,

In hibernate.cfg.xml:

In Customer.hbm.xml:

Hope that helps!!
