Hi ,
I am new in hibernate.I am trying deploy a project and getting an error --
"problem parsing configuration/hibernate.cfg.xml
Exception in thread "main" java.lang.NullPointerException
at FirstExample.main(FirstExample.java:31)"


Development steps:-
1> Install mySql at "C:\Program Files\MySQL\MySQL Server 5.0" [provide password "abhra" when installed]
create new database with command mysql> create database hibernatetutorial ;
and use it with mysql> use hibernatetutorial;
2> In eclipse create 2 .class and 2 xml files under src directory
3> Contact.java--
public class Contact {
private String firstName;
private String lastName;
private String email;
private long id;

public String getEmail() {
return email;
}
public String getFirstName() {
return firstName;
}
public String getLastName() {
return lastName;
}
public void setEmail(String string) {
email = string;
}
public void setFirstName(String string) {
firstName = string;
}
public void setLastName(String string) {
lastName = string;
}
public long getId() {
return id;
}
public void setId(long l) {
id = l;
}
}


FirstExample.java

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class FirstExample {
public static void main(String[] args){
Session session = null;
try{
SessionFactory sessionFactory = new
Configuration().configure().buildSessionFactory();

session=sessionFactory.openSession();
System.out.println("Inserting Record");

Contact contact = new Contact();
contact.setId(3);
contact.setFirstName("Abhra");
contact.setLastName("Kar");
contact.setEmail("karabhra83@gmail.com");
session.save(contact);
System.out.println("Done");
}catch(Exception e){
System.out.println(e.getMessage());
}finally{
session.flush();
session.close();
}
}
}


contact.hbm.xml---
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

</property>

<property name="lastName">
<column name="LASTNAME" />
</property>

<property name="email">

</property>

</class>
</hibernate-mapping>


hibernate.cfg.xml ---
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC

<property name="show_sql">true</property>
<property name="hbm2ddl.auto">update</property>

<mapping resource="contact.hbm.xml"/>

</session-factory>
</hibernate-configuration>


the <session-factory> tab is showing error--
" The content of session-factory must match (property*,mapping*,(class-cache|collection-cache)*,event*,listener*)"
I am not getting any idea what is happening here.
Please help me to solve the error.

Thanks
