[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - jboss 4.2 Hibernate 3.2 entity mapping problem

[cgrahamatip]

I am trying to get a test jsf application to work on the standard jboss 4.2.0 AS server.  I am using eclipse as the IDE. I set the build path in my eclipse project to point to jboss/default/lib jar files for hibernate and other required jars. 

when I deployed the application everythings works as it should until I make a call from a backing bean to query or load a hibernate class.  I get the following error:  "org.hibernate.MappingException: Unknown entity: com.ipi.jsfapp.model.People".

Any information would be greatly appreciated..

The configuration snippets are:
