[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Mapping exception

[gailcassar85]

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
