Hibernate Maping error

[trupti nigam]

I am very new to hibernate and going through some exercise tutorials.
I am following each step in the tutorials and I tried to run my first hibernate app but I get below error.

[java] Initial SessionFactory creation failed.org.hibernate.InvalidMappingE
xception: Could not parse mapping document from resource events/Event.hbm.xml
[java] Exception in thread "main" java.lang.ExceptionInInitializerError
[java] at util.HibernateUtil.<clinit>(Unknown Source)
[java] at events.EventManager.createAndStoreEvent(Unknown Source)

[java] Caused by: org.hibernate.InvalidMappingException: Could not parse ma
pping document from resource events/Event.hbm.xml
[java] at org.hibernate.cfg.Configuration.addResource(Configuration.jav
a:575)

My directory structure is as follows:

hibernateTutorial
+ src
+events
event.java
eventManager.java
event.hbm.xml
+util
HibernateUtil.java
Hibernate.cfg.xml

The event.hbm.xml looks like below:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

    <class name="events.Event" table="EVENTS">
        <id name="Id" column="EVENT_ID">
            <generator class="native"/>
        </id>
        <property name="date" type="timestamp" column="EVENT_DATE"/>
        <property name="title"/>
    </class>

</hibernate-mapping>

The hibernate.cfg.xml looks like below:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

    <session-factory>

        <!-- Database connection settings -->

        <!-- Drop and re-create the database schema on startup -->
        <property name="hbm2ddl.auto">create</property>

        <mapping resource="events/Event.hbm.xml"/>

    </session-factory>

</hibernate-configuration>

I am using hsqldb.

EventManager class looks like below:

package events;

import org.hibernate.Session;
import util.*;
import java.util.Date;

public class EventManager {
	
	public static void main(String[] args) {
        EventManager mgr = new EventManager();

        if (args[0].equals("store")) {
            mgr.createAndStoreEvent("My Event", new Date());
        }

        HibernateUtil.getSessionFactory().close();
    }

    private void createAndStoreEvent(String title, Date theDate) {

        Session session = HibernateUtil.getSessionFactory().getCurrentSession();

        session.beginTransaction();

        Event theEvent = new Event();
        theEvent.setTitle(title);
        theEvent.setDate(theDate);

can someone plese let me know what is wrong with the mapping file.

thanks

Is Event.hbm.xml in your classpath?

[trupti nigam]

Thanks a lot.
The issue is resolved.
You are right, the xml mapping file was not in calsspath due to which I was getting the error message.
I could run the example.

thanks
