"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-configuration>
<session-factory>

<property name="connection.driver_class">org.hsqldb.jdbcDriver </property>
<property name="connection.url">jdbc:hsqldb:data/music</property>
<property name="connection.username">sa</property>
<property name="connection.password"></property>


<property name="connection.pool_size">1</property>


<property name="dialect">org.hibernate.dialect.HSQLDialect</property>
<property name="show_sql">true</property>


<property name="hdm2ddl.auto">create </property>
<mapping resource="Event.hbm.xml" />
</session-factory>

</hibernate-configuration>

my ant target is having this info

<target name ="run" depends="compile" >
<java fork="true" classname="EventManager" classpathref="project.class.path">
<classpath path="${class.root}" />
<arg value="${action}"/>
</java>

try to find out what the complete stack trace is. It seems to be some bug in your cfg.xml file.

I´m having the same problem creating a hibernate session factory using the Hibernate Tools plugin 3.0.0.alpha4a through 'Hibernate Console Perspective'.

Here is the complete stack trace:

you added the mapping file twice probably.

one in cfg.xml and in the list of mapping files.
