I am using Hibernate Core 3.2.2 with Jboss Application Server 4.0.5GA. I managed to map my entities using myEntity.hbm.xml file for each. However, now I would like to use Hibernate Annotations to facilitate mapping especially when having attribute ovverrides in an embeddable class.

I have replaced the myEntity.hbm.xml files with hibernate.cfg.xml file which includes a list of mapping classes as follows. I have placed the config file in the root of my source code outside any package.

<?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>
jdbc:mysql://localhost/myDB

guest
password
com.mysql.jdbc.Driver
org.hibernate.dialect.MySQLDialect
org.hibernate.transaction.JTATransactionFactory
thread
true
create
<!-- mapping files -->

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

However when I run my application and arrive at the point of saving one of my entities, the following exception is thrown:

org.hibernate.MappingException: Unknown entity: com.company.test.ejb.entity.TestEntity
at org.hibernate.impl.SessionFactoryImpl.getEntityPersister (SessionFactoryImpl.java:548)

at org.hibernate.impl.SessionImpl.save (SessionImpl.java:519)
at com.company.test.ejb.session.myTestApp.method1(TestThread.java:70)

So I'm assuming that during deployment the hibernate.cfg.xml is not being considered. Am I placing the file in the wrong place or do I have to add some configuration settings to Jboss?

Thanks
Gail
