    jboss 4.2 Hibernate 3.2 entity mapping problem

    Clair Graham Newbie

      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:
