Getting org.hibernate.InvalidMappingException: Unable to read XML

Question

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.

log4j:WARN No appenders could be found for logger (org.jboss.logging). log4j:WARN Please initialize the log4j system properly.

The error shows

The element type "hibernate-mapping" must be terminated by the matching end-tag

Therefore add a matching closing tag for this element in Department.hbm.xml as expected by the XML parser

</hibernate-mapping>

Similarly add a closing hibernate-configuration element in hibernate.cfg.xml

</hibernate-configuration>

Sometimes is because you have a break line in the start of XML file.

<!--Sure that no exists break line here.-->
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping> 
    <class name="hibernate.Person" table="PEOPLES">
        <id name="id" column="ID">
            <generator class="foreign"> 
            <param name="property">adress</param> 
        </generator>
        </id>

        <property name="name" /> 

        <one-to-one name="adress" cascade="persist, delete"/> 
    </class> 
</hibernate-mapping>
