hi,

i'm trying to set up a simple hibernate application, where i have two tables in my database, represented by two POJOs (Group.java and Story.java). I am using PostgreSQL as my database.

My problem is that I am getting the following exception when this line of code executes:

sessionFactory = new Configuration().configure().buildSessionFactory();

Initial SessionFactory creation failed.org.hibernate.InvalidMappingException: Could not parse mapping document from resource Group.hbm.xml
Exception in thread "main" java.lang.ExceptionInInitializerError

The Group.hbm.xml file is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping
PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">

<hibernate-mapping>
<class name="Group" table="grouptable">
<id name="id" unsaved-value="0">
<generator class="increment"/>
</id>

<set name="stories" cascade="all" inverse="true">
<key column="parent_id"/>
<one-to-many class="Story"/>
</set>

<property name="name" type="string"/>
</class>
</hibernate-mapping>

My hibernate.cfg.xml file is as follows:

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">org.postgresql.Driver</property>
<property name="connection.url">jdbc:postgresql://localhost:5432/hibernateTutorial</property>
<property name="connection.username">postgres</property>
<property name="connection.password">mypassword</property>

<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>

<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>

<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>

<!-- Mapping files -->
<mapping resource="Group.hbm.xml"/>
<mapping resource="Story.hbm.xml"/>
</session-factory>
</hibernate-configuration>


I can't figure out why I'm getting the error for "could not parse mapping document from resource Group.hbm.xml".

Any guidance as to where I may be going wrong will be very helpful.

Thanks!
