Deploying EJB3.0 entity bean

Hi,
I am deploying EJB3.0 Entity bean on JBoss 4.0.1sp1.
I am having ejb-jar.xml and persistence.xml in my META-INF and
Entity bean is not using any Remote Interface; as another Stateless SessionBean is instantiating the POJO Entitbean FileDetailsServiceBO and using EntityManager for persistence.

I get following error , Pls help.
