getting org.hibernate.InvalidMappingException: Unable to read XML

I am using NetbeansIDE 7.2. and pgAdmin III PostgreSQL 9.2 with Database name "StudentReports". I know a little of Hibernate and generating JasperReports using native SQL through JDBC Connection. But I am new to generating JasperReports connecting thru Hibernate Connection which this tutorial shows.

I am getting org.hibernate.InvalidMappingException: Unable to read XML Error and NEVER made a successful Hibernate Connection test, an error pops up saying "Could not parse mapping document from resource com/report/mappings/Department.hbm.xml", after following this tutorial "JasperReports with Hibernate - Module 1" and JasperReports with Hibernate - Module 2. It has 2 Modules. But I did a little modifications on its data access object (DAO) files and I just wanted to have a Department Records. Also, I used a different version of Hibernate and Jasper Reports Package and iReport Plugin for Netbeans which are Hibernate Release 4.1.9 and Jasper Reports 5.0.1 and iReport-4.5.0. I have added all of the jar files of it to my project's Library.

This is my first time handling hibernate mapping xml files and data access object files. These may sound easy for others but I really tried my part too on solving these on my own but seems I don't get it. So, Please help me figuring out these problems. I will really appreciate any help.

Thanks!
