Hibernate Tutorial - Fix 4 of 6 - Maven Unable to Find the Hibernate Mapping File

Preface:
I tried to follow the Hibernate Tutorial posted on official Hibernate site. Here is the link to the tutorial. I was using Apache Maven version 2.2.1 and I had to make a lot of modifications to the tutorial code (specially in pom.xml) to make it work. I want to post these fixes/code updates and maybe it might help someone who is having problems walking through the tutorial.

There were so many issues and the post was getting big so I am splitting it into different posts. you can skip reading the 'preface' section of the other posts in this series.

Problem 4 of 6:

mvn exec:java -Dexec.mainClass="org.hibernate.tutorial.EventFactory" -Dexec.args="store"

And I was getting the following error:
I was getting the following error:

I moved the hibernate mapping files in to the 'resources' folder, saving the package directory structure.
C:\Users\Krishna\workspace\hibernate\src\main\resources\org\hibernate\tutorial\domain\Event.hbm.xml
Note: C:\Users\Krishna\workspace\hibernate is my project root.
